- migrate all old editor posts to new editor format
- ensure we protect the code against mobiledoc or html field being null
- ensure we create a blank mobiledoc structure if mobiledoc field is null (model layer)
- ensure you can fully rollback 2.0 to 1.0
- keep mobiledoc/markdown version 1 logic to be able to rollback (deprecated code)

- go over code base again and double check that all docs links are correct
- 2.0 will become the latest version on our readme pages
refs 9742
- when we've introduced Ghost 1.0, we have noticed that we broke Disqus comments
- Disqus comments use a unique identifier, which is the post id
- that means if you have exported your LTS content and imported it into 1.0, all resource identifiers are regenerated
- but the Disqus must use the original post resource id
- that's why we have imported the old post id and remembered it in the `amp` field 🤠
- that was the only field which was available and un-used
- now in Ghost 2.0, we would like to rename the `amp` field to `comment_id`
- string length: 50 (i thought it might be safer to not use 24 characters, because who knows if support other comment id's in the future)
no issue
- discovered while testing
- SQLite3 has a restriction that you cannot query more than 999 SQL variables (e.g. fetch all tag relations for all posts)
- if you have more than 999 posts in your database, Ghost wasn't able to finish the bootstrap
- the url service tried to fetch all posts & relations, but could not complete, because SQlite3 has thrown
-> "too many SQL variables"
- i have added a recursive query strategy only for SQLite3
- use offset/limit
no issue
- add a new migration for 1.25 to insert the draft demo post for existing blogs
- ensure new blogs get the draft demo post as well
- tested on sqlite3 + mysql
- added handling if Ghost Author user doesn't exist anymore (fallback to owner user)
refs #9742
- Ghost 2.0 is coming
- all doc links in 1.0 must use concrete links e.g. docs.ghost.org/v1 or themes.ghost.org/v1.23.0/
- if we release Ghost 2.0, docs.ghost.org will show 2.0 docs
no issue
- reported in the forum: https://forum.ghost.org/t/publishing-with-a-single-post-request-to-posts/1648
- the defaults are defined in two places
1. on the schema level (defaults for the database)
2. on the ORM (model layer)
- the defaults on the db layer are set correctly when inserting a new resource
- but if we don't apply all defaults on the model layer, it will happen that model events are emitted without the correct defaults
- see comment in code base
- it's caused by the fact that knex only returns the inserted resource id (probably caused by the fact knex has to support x databases)
- components/modules are listening on model events and expect:
1. a complete set of attributes
2. a complete set of defaults
3. sanitized values e.g. bool, date
- this commit fixes:
1. added missing defaults for user & post model
2. sanitize booleans (0|1 => false|true)
3. added tests to ensure this works as expected
4. clarfies the usage of `defaults`
Regarding https://forum.ghost.org/t/publishing-with-a-single-post-request-to-posts/1648:
- the post event was emitted with the following values {page: undefined, featured: undefined}
- the urlservice receives this event and won't match the resource against collection filters correctly
- NOTE: the post data in the db were correct
refs #9601
- the home.hbs behaviour for the index collection (`/`) is hardcoded in Ghost
- we would like to migrate all existing routes.yaml files
- we only replace the file if the contents of the routes.yaml file equals the old routes.yaml format (with home.hbs as template)
- updated README of settings folder
- if we don't remove the home.hbs template from the default routes.yaml file, home.hbs will be rendered for any page of the index collection
- the backwards compatible behaviour was different
- only render home.hbs for page 1
- remember: the default routes.yaml file reflects how Ghost was working without dynamic routing
refs #9601
### Dynamic Routing
This is the beta version of dynamic routing.
- we had a initial implementation of "channels" available in the codebase
- we have removed and moved this implementation
- there is now a centralised place for dynamic routing - server/services/routing
- each routing component is represented by a router type e.g. collections, routes, static pages, taxonomies, rss, preview of posts
- keep as much as possible logic of routing helpers, middlewares and controllers
- ensure test coverage
- connect all the things together
- yaml file + validation
- routing + routers
- url service
- sitemaps
- url access
- deeper implementation of yaml validations
- e.g. hard require slashes
- ensure routing hierarchy/order
- e.g. you enable the subscriber app
- you have a custom static page, which lives under the same slug /subscribe
- static pages are stronger than apps
- e.g. the first collection owns the post it has filtered
- a post cannot live in two collections
- ensure apps are still working and hook into the routers layer (or better said: and register in the routing service)
- put as much as possible comments to the code base for better understanding
- ensure a clean debug log
- ensure we can unmount routes
- e.g. you have a collection permalink of /:slug/ represented by {globals.permalink}
- and you change the permalink in the admin to dated permalink
- the express route get's refreshed from /:slug/ to /:year/:month/:day/:slug/
- unmount without server restart, yey
- ensure we are backwards compatible
- e.g. render home.hbs for collection index if collection route is /
- ensure you can access your configured permalink from the settings table with {globals.permalink}
### Render 503 if url service did not finish
- return 503 if the url service has not finished generating the resource urls
### Rewrite sitemaps
- we have rewritten the sitemaps "service", because the url generator does no longer happen on runtime
- we generate all urls on bootstrap
- the sitemaps service will consume created resource and router urls
- these urls will be shown on the xml pages
- we listen on url events
- we listen on router events
- we no longer have to fetch the resources, which is nice
- the urlservice pre-fetches resources and emits their urls
- the urlservice is the only component who knows which urls are valid
- i made some ES6 adaptions
- we keep the caching logic -> only regenerate xml if there is a change
- updated tests
- checked test coverage (100%)
### Re-work usage of Url utility
- replace all usages of `urlService.utils.urlFor` by `urlService.getByResourceId`
- only for resources e.g. post, author, tag
- this is important, because with dynamic routing we no longer create static urls based on the settings permalink on runtime
- adapt url utility
- adapt tests

- we add bookshelf-relations step by step if we need it
- with https://github.com/TryGhost/Ghost/pull/9592 we have rewritten the test env to use Bookshelf
- this is important for our new url service
- because the service is listening on model updates and updates the urls based on the model events
- so with moving to Bookshelf, we need any easy way to add relations
- the test env inserts test fixtures
- it adds permissions and each permission get's roles attached
- `models.Permission.add({roles: [...]})
no issue
- replaced token creation by `lib.common.security`
- added unit tests for adding invites
- allow a different invite status for internal access
refs https://github.com/TryGhost/Team/issues/65
We are currently work on dynamic routing (aka channels).
An important piece of this feature is the url service, which always knows the url of a resource at any time.
Resources can belong to collections or taxonomies, which can be defined in a [routing yaml file](https://github.com/TryGhost/Ghost/issues/9528). We are currently shipping portions, which will at end form the full dynamic routing feature.
### Key Notes
- each routing type (collections, taxonomies, static pages) is registered in order - depending on the yaml routes file configuration
- static pages are an internal concept - they sit at the end of the subscriber queue
- we make use of a temporary [`Channels2`](https://github.com/TryGhost/Ghost/pull/9550/files#diff-9e7251409844521470c9829013cd1563) file, which simulates the current static routing in Ghost (this file will be modified, removed or whatever - this is one of the next steps)
- two way binding: you can ask for a resource url based on the resource id, you can ask for the resource based on the url
- in theory it's possible that multiple resources generate the same url: we don't handle this with collision (because this is error prone), we handle this with the order of serving content. if you ask the service for a resource, which lives behind e.g. /test/, you will get the resource which is served
- loose error handling -> log errors and handle instead of throw error and do nothing (we log the errors with a specific code, so we can react in case there is a bug)
- the url services fetches all resources on bootstrap. we only fetch and keep a reduced set of attributes (basically the main body of a resource)
- the bootstrap time will decrease a very little (depending on the amount of resources you have in your database)
- we still offer the option to disable url preloading (in your config `disableUrlPreload: true`) - this option will be removed as soon as the url service is connected. You can disable the service in case you encounter a problem
- **the url service is not yet connected, we will connect the service step by step. The first version should be released to pre-catch bugs. The next version will add 503 handling if the url service is not ready and it will consume urls for resources.**
----
- the url service generates urls based on resources (posts, pages, users, tags)
- the url service keeps track of resource changes
- the url service keeps track of resource removal/insert
- the architecture:
- each routing type is represented by a url generator
- a routing type is a collection, a taxonomiy or static pages
- a queue which ensures that urls are unique and can be owned by one url generator
- the hierarchy of registration defines that
- we query knex, because bookshelf is too slow
- removed old url service files + logic
- added temp channels alternative (Channels2) -> this file will look different soon, it's for now the temporary connector to the url service. Also the name of the file is not optimal, but that is not really important right now.
no issue
- required for model events
- otherwise you won't receive a full data set
- in worst case you have to re-fetch the post
- required for the url service
- the url service always needs relations (authors,tags) to be able to generate the url properly
@IMPORTANT
- no API change, we still return what you are asking for
- we first edit/add the resource
- then we fetch the data with the API options
- @TODO: this can be optimised and will improve performance
picking/selecting it from the insert/update response
- this is an internal change
closes#9547
- you setup a blog with the following owner:
- email: test@ghost.org
- name: test
- slug: test
- now you import a JSON db file, which holds the exact same owner
- this owner won't be imported, because it's a duplicate
- but the slug is different (!)
- the importer tries to find a matching existing user, but won't find anything
- the importer then send an empty authors array `post.authors=[]` into the model layer
- this is not allowed -> this would mean, you are actively trying to unset all authors
no issue
- if multiple queries run in a transaction, the model events are triggered before the txn finished
- if the txn rolls back, the events are anyway emitted
- the events are triggered too early
- solution:
- `emitChange` needs to detect that a transaction is happening
- it listens on a txn event to determine if events should be triggered
no issue
- add a big comment
- describe:
- how this works
- why this is in place
- what does currently not work
- and why it will work with channels
- @TODO:
- figure out how to disallow:
- `models.Post.findAll({columns: id})`
- `post.save(data)`
- this will trigger bookshelf events and model events
- url generation currently needs a set of attributes (e.g. slug, published_at)
- will be auto-fixed with channels, because you can call `urlService.getUrl(post.id)`
- but what doesn't get solved is our model events
- e.g. `emitChange` needs `post.get('page')` to determine if it's a page
no issue
- this is no longer needed for now
- it was anyway a little bit ugly to modify bookshelf's `changed` object
- if we want to change something about figuring out if a model has changed (including relations)
-> we probably need to override bookshelf
refs #9548
- we always receive date strings from the client in ISO format
- we ensure that we transform these strings into JS dates for comparison
- when the client sends relations, we need to ensure that relations are checked as well
- will only work for the post model for now, because this is the only model which uses `bookshelf-relations`
- added unit tests
- removed some model tests, which do the same
no issue
This PR adds the server side logic for multiple authors. This adds the ability to add multiple authors per post. We keep and support single authors (maybe till the next major - this is still in discussion)
### key notes
- `authors` are not fetched by default, only if we need them
- the migration script iterates over all posts and figures out if an author_id is valid and exists (in master we can add invalid author_id's) and then adds the relation (falls back to owner if invalid)
- ~~i had to push a fork of bookshelf to npm because we currently can't bump bookshelf + the two bugs i discovered are anyway not yet merged (https://github.com/kirrg001/bookshelf/commits/master)~~ replaced by new bookshelf release
- the implementation of single & multiple authors lives in a single place (introduction of a new concept: model relation)
- if you destroy an author, we keep the behaviour for now -> remove all posts where the primary author id matches. furthermore, remove all relations in posts_authors (e.g. secondary author)
- we make re-use of the `excludeAttrs` concept which was invented in the contributors PR (to protect editing authors as author/contributor role) -> i've added a clear todo that we need a logic to make a diff of the target relation -> both for tags and authors
- `authors` helper available (same as `tags` helper)
- `primary_author` computed field available
- `primary_author` functionality available (same as `primary_tag` e.g. permalinks, prev/next helper etc)
closes#9520
- it contains a dependency bump of the latest Bookshelf release
- Bookshelf introduced a bug in the last release
- see https://github.com/bookshelf/bookshelf/pull/1583
- see https://github.com/bookshelf/bookshelf/pull/1798
- this has caused trouble in Ghost
- the `updated_at` attribute was not automatically set anymore
---
The bookshelf added one breaking change: it's allow to pass custom `updated_at` and `created_at`.
We already have a protection for not being able to override the `created_at` date on update.
We had to add another protection to now allow to only change the `updated_at` property.
You can only change `updated_at` if you actually change something else e.g. the title of a post.
To be able to implement this check i discovered that Bookshelfs `model.changed` object has a tricky behaviour.
It remembers **all** attributes, which where changed, doesn't matter if they are valid or invalid model properties.
We had to add a line of code to avoid remembering none valid model attributes in this object.
e.g. you change `tag.parent` (no valid model attribute). The valid property is `tag.parent_id`.
If you pass `tag.parent` but the value has **not** changed (`tag.parent` === `tag.parent_id`), it will output you `tag.changed.parent`. But this is wrong.
Bookshelf detects `changed` attributes too early. Or if you think the other way around, Ghost detects valid attributes too late.
But the current earliest possible stage is the `onSaving` event, there is no earlier way to pick valid attributes (except of `.forge`, but we don't use this fn ATM).
Later: the API should transform `tag.parent` into `tag.parent_id`, but we are not using it ATM, so no need to pre-optimise.
The API already transforms `post.author` into `post.author_id`.
refs #9519
- `errors.models.posts.postNotFound` -> wrong
- `errors.models.post.postNotFound` -> correct
- the i18n lib just logs the error and falls back to a valid error key
- wrong i18n keys will never break Ghost
closes#9085
Fixes an issue, where the client sets image properties to `""` after deleting the image. This causes problems with the query filter (see https://github.com/TryGhost/GQL/issues/24), as they have to be `null`.
Added a check in the model layer saving method to set value to `null`, when the property is empty.
Affected models and properties:
- `posts`:
- `feature_image`
- `og_image`
- `twitter_image`
- `users`:
- `profile_image`
- `cover_image`
- `tags`:
- `feature_image`
no issue
- currently if you would like to edit a resource (e.g. post) and you pass an invalid model id, the following happens
- permission check calls `Post.permissible`
- the Post could not find the post, but ignored it and returned `userPermissions:true`
- then the model layer is queried again and figured out that the post does not exist
- A: there is no need to query the model twice
- B: we needed proper error handling for post and role model
no issue
- replace logic for preparing nested tags
- if you have nested tags in your file, we won't update or update the target tag
- we simply would like to add the relationship to the database
- use same approach as base class
- add `posts_tags` to target post model
- update identifiers
- insert relation by foreign key `tag_id`
- bump bookshelf-relations to 0.1.10
no issue
- change behaviour from updating user references after the actual import to update the user reference before the actual import
- updating user references after the import is way less case intense
- that was the initial decision for updating the references afterwards
- but that does not play well with adding nested relations by identifier
- the refactoring is required for multiple authors
- if we e.g. store invalid author id's, we won't be able to add a belongs-to-many relation for multiple authors
- bookshelf-relations is generic and always tries to find a matching target before attching a model
- invalid user references won't work anymore
- this change has a very good side affect
- 17mb takes on master ~1,5seconds
- on this branch it takes ~45seconds
- also the memory usage is way lower and stabler
- 40mb takes 1,6s (times out on master)
no issue
- otherwise we will have trouble in the future fetching relations by foreign key
- e.g. `tag_id: {id}`
- this won't work if we don't explicitly define the name of the keys
- bookshelf can't fulfil the request
- this does not change any behaviour, it just makes use of the ability to define the names of your foreign keys
refs https://github.com/TryGhost/Ghost/issues/3658
- the `validateSchema` helper was a bit broken
- if you add a user without email, you will receive a database error
- but the validation error should catch that email is passed with null
- it was broken, because:
- A: it called `toJSON` -> this can remove properties from the output (e.g. password)
- B: we only validated fields, which were part of the JSON data (model.hasOwnProperty)
- we now differentiate between schema validation for update and insert
- fixed one broken import test
- if you import a post without a status, it should not error
- it falls back to the default value
- removed user model `onValidate`
- the user model added a custom implementation of `onValidate`, because of a bug which we experienced (see https://github.com/TryGhost/Ghost/issues/3638)
- with the refactoring this is no longer required - we only validate fields which have changed when updating resources
- also, removed extra safe catch when logging in (no longer needed - unit tested)
- add lot's of unit tests to proof the code change
- always call the base class, except you have a good reason
no issue
- `isNew` does not work in Ghost, because Ghost does not use auto increment id's
- see https://github.com/bookshelf/bookshelf/issues/1265
- see https://github.com/bookshelf/bookshelf/blob/0.10.3/src/base/model.js#L211
- we only had one occurance, which was anyway redundant
- if you add a user, `hasChanged('password') is true
- if you edit a user and the password has changed, `hasChanged('password')` is true as well
NOTE #1:
1. We can't override `isNew` and throw an error, because bookshelf makes use of `isNew` as well, but it's a fallback if `options.method` is not set.
2. It's hard to re-implement `isNew` based on `options.method`, because then we need to ensure that this value is always set (requires a couple of changes)
NOTE #2:
If we need to differentiate if a model is new or edited, we should manually check for `options.method === insert`.
NOTE #3:
The unit tests are much faster compared to the model integration tests.
I did a comparision with the same test assertion:
- unit test takes 70ms
- integration test takes 190ms
no issue
- move password hashing and password comparison to lib/security/password
- added two unit test
- FYI: password hashing takes ~100ms
- we could probably mock password hashing in certain cases when unit testing
no issue
- this commit cleans up the usages of `include` and `withRelated`.
### API layer (`include`)
- as request parameter e.g. `?include=roles,tags`
- as theme API parameter e.g. `{{get .... include="author"}}`
- as internal API access e.g. `api.posts.browse({include: 'author,tags'})`
- the `include` notation is more readable than `withRelated`
- and it allows us to use a different easier format (comma separated list)
- the API utility transforms these more readable properties into model style (or into Ghost style)
### Model access (`withRelated`)
- e.g. `models.Post.findPage({withRelated: ['tags']})`
- driven by bookshelf
---
Commits explained.
* Reorder the usage of `convertOptions`
- 1. validation
- 2. options convertion
- 3. permissions
- the reason is simple, the permission layer access the model layer
- we have to prepare the options before talking to the model layer
- added `convertOptions` where it was missed (not required, but for consistency reasons)
* Use `withRelated` when accessing the model layer and use `include` when accessing the API layer
* Change `convertOptions` API utiliy
- API Usage
- ghost.api(..., {include: 'tags,authors'})
- `include` should only be used when calling the API (either via request or via manual usage)
- `include` is only for readability and easier format
- Ghost (Model Layer Usage)
- models.Post.findOne(..., {withRelated: ['tags', 'authors']})
- should only use `withRelated`
- model layer cannot read 'tags,authors`
- model layer has no idea what `include` means, speaks a different language
- `withRelated` is bookshelf
- internal usage
* include-count plugin: use `withRelated` instead of `include`
- imagine you outsource this plugin to git and publish it to npm
- `include` is an unknown option in bookshelf
* Updated `permittedOptions` in base model
- `include` is no longer a known option
* Remove all occurances of `include` in the model layer
* Extend `filterOptions` base function
- this function should be called as first action
- we clone the unfiltered options
- check if you are using `include` (this is a protection which could help us in the beginning)
- check for permitted and (later on default `withRelated`) options
- the usage is coming in next commit
* Ensure we call `filterOptions` as first action
- use `ghostBookshelf.Model.filterOptions` as first action
- consistent naming pattern for incoming options: `unfilteredOptions`
- re-added allowed options for `toJSON`
- one unsolved architecture problem:
- if you override a function e.g. `edit`
- then you should call `filterOptions` as first action
- the base implementation of e.g. `edit` will call it again
- future improvement
* Removed `findOne` from Invite model
- no longer needed, the base implementation is the same
refs #6103
- simplify `toJSON`
- `baseKey` was not used - have not find a single use case
- all the functionality of our `toJSON` is offered in bookshelf
- `omitPivot` does remove pivot elements from the JSON obj (bookshelf feature)
- `shallow` allows you to not return relations
- make use of `serialize`, see http://bookshelfjs.org/docs/src_base_model.js.html#line260
- fetching nested relations e.g. `users.roles` still works (unrelated to this refactoring)
> pick('shallow', 'baseKey', 'include', 'context')
We will re-add options validation in https://github.com/TryGhost/Ghost/pull/9427, but then with the official way: use `filterOptions`.
---
We return all fetched relations (pre-defined with `withRelated`) by default.
You can disable it with `shallow:true`.

- Remove hardcoded notification in admin controller
- NOTE: update check notifications are no longer blocking the admin rendering
- this is one of the most import changes
- we remove the hardcoded release message
- we also remove adding a notification manually in here, because this will work differently from now on
-> you receive a notification (release or custom) in the update check module and this module adds the notification as is to our database
- Change default core settings keys
- remove displayUpdateNotification
-> this was used to store the release version number send from the UCS
-> based on this value, Ghost creates a notification container with self defined values
-> not needed anymore
- rename seenNotifications to notifications
-> the new notifications key will hold both
1. the notification from the USC
2. the information about if a notification was seen or not
- this key hold only one release notification
- and n custom notifications
- Update Check Module: Request to the USC depends on the privacy configuration
- useUpdateCheck: true -> does a checkin in the USC (exposes data)
- useUpdateCheck: false -> does only a GET query to the USC (does not expose any data)
- make the request handling dynamic, so it depends on the flag
- add an extra logic to be able to define a custom USC endpoint (helpful for testing)
- add an extra logic to be able to force the request to the service (helpful for testing)
- Update check module: re-work condition when a check should happen
- only if the env is not correct
- remove deprecated config.updateCheck
- remove isPrivacyDisabled check (handled differently now, explained in last commit)
- Update check module: remove `showUpdateNotification` and readability
- showUpdateNotification was used in the admin controller to fetch the latest release version number from the db
- no need to check against semver in general, the USC takes care of that (no need to double check)
- improve readability of `nextUpdateCheck` condition
- Update check module: refactor `updateCheckResponse`
- remove db call to displayUpdateNotification, not used anymore
- support receiving multiple custom notifications
- support custom notification groups
- the default group is `all` - this will always be consumed
- groups can be extended via config e.g. `notificationGroups: ['migration']`
- Update check module: refactor createCustomNotification helper
- get rid of taking over notification duplication handling (this is not the task of the update check module)
- ensure we have good fallback values for non present attributes in a notification
- get rid of semver check (happens in the USC) - could be reconsidered later if LTS is gone
- Refactor notification API
- reason: get rid of in process notification store
-> this was an object hold in process
-> everything get's lost after restart
-> not helpful anymore, because imagine the following case
-> you get a notification
-> you store it in process
-> you mark this notification as seen
-> you restart Ghost, you will receive the same notification on the next check again
-> because we are no longer have a separate seen notifications object
- use database settings key `notification` instead
- refactor all api endpoints to support reading and storing into the `notifications` object
- most important: notification deletion happens via a `seen` property (the notification get's physically deleted 3 month automatically)
-> we have to remember a seen property, because otherwise you don't know which notification was already received/seen
- Add listener to remove seen notifications automatically after 3 month
- i just decided for 3 month (we can decrease?)
- at the end it doesn't really matter, as long as the windows is not tooooo short
- listen on updates for the notifications settings
- check if notification was seen and is older than 3 month
- ignore release notification
- Updated our privacy document
- Updated docs.ghost.org for privacy config behaviour
- contains a migration script to remove old settings keys
