closes#9832
The API _should_ be returning absolute URLs for everything, 3rd party applications require absolute urls to read and display ghost data correctly. Currently they have to concat the blog url and the resource url, which is very uncomfortable.
Changing the public api like this would be considered a breaking change however so we've opted to put it behind a query parameter named `absolute_urls`.
no issue
- we have to explicitly reset the previous `updated_at` field, because Bookshelf auto-updates this field on each update
- we have to extend the condition to avoid updating the `updated_by` field
- detect and respect `options.migrating`
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)

### 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
refs https://github.com/TryGhost/Ghost/pull/9592
- 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: [...]})
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
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
- 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`.
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
- 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)
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
- 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`.
refs #9127
- permission checks can happen everywhere in the code base
- we would like to create a context class
- global access to `options.context.is(...)`
- please read more about the access plugin in #9127 section "Model layer and the access plugin".
- removed the plugin and use direct context checks
closes#8717
- this is now required, because we run import queries sequentiell
- this code protects two cases:
- you have duplicate slugs in the JSON file (the first get's inserted, the second get's ignored)
- you have an existing slug in the database and you try to import the same slug, get's ignored
no issue
> Deprecation warning: value provided is not in a recognized ISO format. moment construction falls back to js Date(), which is not reliable across all browsers and versions.

- this logic belongs to a static model helper
- the visibility property is a model property, the knowledge about the visibility values belongs to the model
- rename the functions, so they make more sense
refs #9178
- we have to take care that we don't end up in circular dependencies
- e.g. API requires UrlService and UrlService needs to require the API (for requesting data)
- update the references
- we would like to get rid of the utils folder, this is/was the most complicated change
no issue
- added https://github.com/TryGhost/bookshelf-relations as dependency
- remove existing tag handling
---
* Important: Ensure we trigger parent initialize function
- otherwise the plugin is unable to listen on model events
- important: event order for listeners is Ghost -> Plugin
- Ghost should be able to listen on the events as first instance
- e.g. be able to modify/validate relationships
* Fix tag validation
- we detect lower/update case slugs for tags manually
- this can't be taken over from the plugin obviously
- ensure we update the target model e.g. this.set('tags', ...)
* override base fn: `permittedAttributes`
- ensure we call the base
- put relations on top
- each relation is allowed to be passed
- the plugin will auto-unset any relations to it does not reach the database
* Ensure we run add/edit/delete within a transaction
- updating nested relationships requires sql queries
- all sql statements have to run in a single transaction to ensure we rollback everything if an error occurs
- use es6
closes#8143
Fixed a potential issue (edge-case), where our generated and validated (in terms of check for existance and add a counter) would return a slug, that will exceed the maximum length of the slug fields (191 chars).
This is mostly possible for the post title, which can be 255 chars long and would generate a slug with the same length. This would prevent the user from actually saving a post.
I tried first to determine the expected length for a slug that already exists, but decided that the **easier** and simplyfied implementation is to always cut a slug to **185 chars** (+ counter). This makes it easier to find duplicates and includes a possible high number of counts (edge-edge-case).
The slug will not be cut down to 185 chars if it's an import.
closes#9089
- use the current date any time a post is fetched if the database contains an invalid date
- raise an error any time an attempt is made to save an invalidate date via the API
no issue
- it's not allowed to change/add these attributes via the API
- created_at = is only once set on adding the resource
- created_by = is only once set on adding the resource
- updated_by = is set on the server side when updating the model (based on who is logged in)
- updated_at = is set on the server side when updating the model
* Revert the usage of the access rules plugin
no issue
- we store dates without milliseconds in the database
- our test environment does not use our model layer to insert data, this is related to https://github.com/TryGhost/Ghost/issues/7196
- so it can happen that the test env inserts unix timestamps instead of a formatted string
- e.g. adding data via the model layer (e.g. via the API) the format is always normalised to `YYYY-MM-DD HH:mm:ss`
- if we fetch the date from the database, we have a hook which sorts out knex returning different formats for dates
- this hook wraps the returned date into a UTC moment date, but adds the current milliseconds on top
- which can collide in tests when you have specific assertions
- use `startOf` to ignore milliseconds
- furthermore: remove the mentionings of `pg` (postgres)
no issue
- this bug fix affects all endpoints for the public user access
- we allowed fetching `roles` via the public api by accident
- see our docs: https://api.ghost.org/docs/users)
- we only allow `count.posts`
- returning roles via the public api exposes too many details
- this was never intentional

- this database rule is based on the owner id being '1', which is wrong when you transfer ownership

- blog is setup if the owner is locked
refs #5422
- we can support null titles after this PR if we want
- user model: fix getAuthorRole
- user model: support adding roles by name
- we support this for roles as well, this makes it easier when importing related user roles (because usually roles already exists in the database and the related id's are wrong e.g. roles_users)
- base model: support for null created_at or updated_at values
- post or tag slugs are always safe strings
- enable an import of a null slug, no need to crash or to cover this on import layer
- add new DataImporter logic
- uses a class inheritance mechanism to achieve an easier readability and maintenance
- schema validation (happens on model layer) was ignored
- allow to import unknown user id's (see https://github.com/TryGhost/Ghost/issues/8365)
- most of the duplication handling happens on model layer (we can use the power of unique fields and errors from the database)
- the import is splitted into three steps:
- beforeImport
--> prepares the data to import, sorts out relations (roles, tags), detects fields (for LTS)
- doImport
--> does the actual import
- afterImport
--> updates the data after successful import e.g. update all user reference fields e.g. published_by (compares the imported data with the current state of the database)
- import images: markdown can be null
- show error message when json handler can't parse file
- do not request gravatar if email is null
- return problems/warnings after successful import
- optimise warnings in importer
- do not return warnings for role duplications, no helpful information
- error handler: return context information of error
- we show the affected json entries as one line in the UI
- show warning for: detected duplicated tag
- schema validation: fix valueMustBeBoolean translation
- remove context property from json parse error
closes#5599
If two users edit the same post, it can happen that they override each others content or post settings. With this change this won't happen anymore.
✨ Update collision for posts
- add a new bookshelf plugin to detect these changes
- use the `changed` object of bookshelf -> we don't have to create our own diff
- compare client and server updated_at field
- run editing posts in a transaction (see comments in code base)
🙀 update collision for tags
- `updateTags` for adding posts on `onCreated` - happens after the post was inserted
--> it's "okay" to attach the tags afterwards on insert
--> there is no need to add collision for inserting data
--> it's very hard to move the updateTags call to `onCreating`, because the `updateTags` function queries the database to look up the affected post
- `updateTags` while editing posts on `onSaving` - all operations run in a transactions and are rolled back if something get's rejected
- Post model edit: if we push a transaction from outside, take this one
✨ introduce options.forUpdate
- if two queries happening in a transaction we have to signalise knex/mysql that we select for an update
- otherwise the following case happens:
>> you fetch posts for an update
>> a user requests comes in and updates the post (e.g. sets title to "X")
>> you update the fetched posts, title would get overriden to the old one
use options.forUpdate and protect internal post updates: model listeners
- use a transaction for listener updates
- signalise forUpdate
- write a complex test
use options.forUpdate and protect internal post updates: scheduling
- publish endpoint runs in a transaction
- add complex test
- @TODO: right now scheduling api uses posts api, therefor we had to extend the options for api's
>> allowed to pass transactions through it
>> but these are only allowed if defined from outside {opts: [...]}
>> so i think this is fine and not dirty
>> will wait for opinions
>> alternatively we have to re-write the scheduling endpoint to use the models directly
no issue
- client dates are sent as ISO format (moment(..).format())
- server dates are in JS Date format
>> when bookshelf fetches data from the database, all dates are transformed into JS dates
>> see `parse` helper function
- Bookshelf updates the model with the client data via Bookshelf's `set` function
- therefor Bookshelf uses a simple `isEqual` function from lodash to detect changes
- .previous(attr) and .get(attr) return false
- that has the concequence that dates are always marked as "changed"
- internally we use our `hasDateChanged` if we have to compare previous/updated dates
- but Bookshelf is not in our control for this case
