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)

- 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.
refs #9178
- 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

- when the ownership get's transferred, the id of the new owner is not '1' anymore
- we previously added a database rule, which signalises if the blog is setup or not, see 827aa15757 (diff-7a2fe80302d7d6bf67f97cdccef1f71fR542)
- this database rule is based on the owner id being '1', which is wrong when you transfer ownership
- we should keep in mind, that the owner id being '1' is only the default Ghost setup, but it can change
- 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
no issue
- i don't know if this never worked or has worked and something changed in bookshelf
- but this fixes: saving the content (no change for published_at) of a scheduled post within the 2minutes window
- add `beforeWrite` option to hasDateChanged helper, see comment
- use previous for `beforeWrite` operations
- add a test and fix some other small issues in the scheduler tests
* 🛠 bookshelf tarball, bson-objectid
* 🎨 schema changes
- change increment type to string
- add a default fallback for string length 191 (to avoid adding this logic to every single column which uses an ID)
- remove uuid, because ID now represents a global resource identifier
- keep uuid for post, because we are using this as preview id
- keep uuid for clients for now - we are using this param for Ghost-Auth
* ✨ base model: generate ObjectId on creating event
- each new resource get's a auto generate ObjectId
- this logic won't work for attached models, this commit comes later
* 🎨 centralised attach method
When attaching models there are two things important two know
1. To be able to attach an ObjectId, we need to register the `onCreating` event the fetched model!This is caused by the Bookshelf design in general. On this target model we are attaching the new model.
2. We need to manually fetch the target model, because Bookshelf has a weird behaviour (which is known as a bug, see see https://github.com/tgriesser/bookshelf/issues/629). The most important property when attaching a model is `parentFk`, which is the foreign key. This can be null when fetching the model with the option `withRelated`. To ensure quality and consistency, the custom attach wrapper always fetches the target model manual. By fetching the target model (again) is a little performance decrease, but it also has advantages: we can register the event, and directly unregister the event again. So very clean code.
Important: please only use the custom attach wrapper in the future.
* 🎨 token model had overriden the onCreating function because of the created_at field
- we need to ensure that the base onCreating hook get's triggered for ALL models
- if not, they don't get an ObjectId assigned
- in this case: be smart and check if the target model has a created_at field
* 🎨 we don't have a uuid field anymore, remove the usages
- no default uuid creation in models
- i am pretty sure we have some more definitions in our tests (for example in the export json files), but that is too much work to delete them all
* 🎨 do not parse ID to Number
- we had various occurances of parsing all ID's to numbers
- we don't need this behaviour anymore
- ID is string
- i will adapt the ID validation in the next commit
* 🎨 change ID regex for validation
- we only allow: ID as ObjectId, ID as 1 and ID as me
- we need to keep ID 1, because our whole software relies on ID 1 (permissions etc)
* 🎨 owner fixture
- roles: [4] does not work anymore
- 4 means -> static id 4
- this worked in an auto increment system (not even in a system with distributed writes)
- with ObjectId we generate each ID automatically (for static and dynamic resources)
- it is possible to define all id's for static resources still, but that means we need to know which ID is already used and for consistency we have to define ObjectId's for these static resources
- so no static id's anymore, except of: id 1 for owner and id 0 for external usage (because this is required from our permission system)
- NOTE: please read through the comment in the user model
* 🎨 tests: DataGenerator and test utils
First of all: we need to ensure using ObjectId's in the tests. When don't, we can't ensure that ObjectId's work properly.
This commit brings lot's of dynamic into all the static defined id's.
In one of the next commits, i will adapt all the tests.
* 🚨 remove counter in Notification API
- no need to add a counter
- we simply generate ObjectId's (they are auto incremental as well)
- our id validator does only allow ObjectId as id,1 and me
* 🎨 extend contextUser in Base Model
- remove isNumber check, because id's are no longer numbers, except of id 0/1
- use existing isExternalUser
- support id 0/1 as string or number
* ✨ Ghost Owner has id 1
- ensure we define this id in the fixtures.json
- doesn't matter if number or string
* 🎨 functional tests adaptions
- use dynamic id's
* 🎨 fix unit tests
* 🎨 integration tests adaptions
* 🎨 change importer utils
- all our export examples (test/fixtures/exports) contain id's as numbers
- fact: but we ignore them anyway when inserting into the database, see https://github.com/TryGhost/Ghost/blob/master/core/server/data/import/utils.js#L249
- in 0e6ed957cd (diff-70f514a06347c048648be464819503c4L67) i removed parsing id's to integers
- i realised that this ^ check just existed, because the userIdToMap was an object key and object keys are always strings!
- i think this logic is a little bit complicated, but i don't want to refactor this now
- this commit ensures when trying to find the user, the id comparison works again
- i've added more documentation to understand this logic ;)
- plus i renamed an attribute to improve readability
* 🎨 Data-Generator: add more defaults to createUser
- if i use the function DataGenerator.forKnex.createUser i would like to get a full set of defaults
* 🎨 test utils: change/extend function set for functional tests
- functional tests work a bit different
- they boot Ghost and seed the database
- some functional tests have mis-used the test setup
- the test setup needs two sections: integration/unit and functional tests
- any functional test is allowed to either add more data or change data in the existing Ghost db
- but what it should not do is: add test fixtures like roles or users from our DataGenerator and cross fingers it will work
- this commit adds a clean method for functional tests to add extra users
* 🎨 functional tests adaptions
- use last commit to insert users for functional tests clean
- tidy up usage of testUtils.setup or testUtils.doAuth
* 🐛 test utils: reset database before init
- ensure we don't have any left data from other tests in the database when starting ghost
* 🐛 fix test (unrelated to this PR)
- fixes a random failure
- return statement was missing
* 🎨 make changes for invites
refs #7494, refs #7495
This PR is an extracted clean up feature of #7495.
We are using everywhere static id checks (userId === 0 or userId === 1).
This PR moves the static values into the Base model.
This makes it 1. way more readable and 2. we can change the id's in a central place.
I changed the most important occurrences - no tests are touched (yet!).
The background is: when changing from auto increment id (number) to ObjectId's (string) we still need to support id 1 and 0, because Ghost relies on these two static id's.
I would like to support using both: 0/1 as string and 0/1 as number.
1 === owner/internal
0 === external
Another important change:
User Model does not longer define the contextUser method, because i couldn't find a reason?
I looked in Git history, see 6e48275160
* 🎨 do not call generateSlug twice for User.setup
* 🎨 call generatePasswordHash onSaving only
- now we can add defaults to User Model
- it was not possible before because add User model did the following:
1. validate password length
2. hash password manually
3. call ghostBookshelf.Model.add and THEN bookshelf defaults fn gets triggered
- call generatePasswordHash in onSaving hook for all use case
- add more tests to user model, juhu
refs #7432
- all models implemented it's own initialize fn to register events
- we can register all events in the base model
- important: we only listen on the event, if the model has defined a hook for it
- this is just a small clean up PR
- register more bookshelf events
* 🎨 move heart of fixtures to schema folder and change user model
- add fixtures.json to schema folder
- add fixture utils to schema folder
- keep all the logic!
--> FIXTURE.JSON
- add owner user with roles
--> USER MODEL
- add password as default
- findAll: allow querying inactive users when internal context (defaultFilters)
- findOne: do not remove values from original object!
- add: do not remove values from original object!
* 🔥 remove migrations key from default_settings.json
- this was a temporary invention for an older migration script
- sephiroth keep alls needed information in a migration collection
* 🔥 add code property to errors
- add code property to errors
- IMPORTANT: please share your opinion about that
- this is a copy paste behaviour of how node is doing that (errno, code etc.)
- so code specifies a GhostError
* 🎨 change error handling in versioning
- no need to throw specific database errors anymore (this was just a temporary solution)
- now: we are throwing real DatabaseVersionErrors
- specified by a code
- background: the versioning unit has not idea about seeding and population of the database
- it just throws what it knows --> database version does not exist or settings table does not exist
* 🎨 sephiroth optimisations
- added getPath function to get the path to init scripts and migration scripts
- migrationPath is still hardcoded (see TODO)
- tidy up database naming to transacting
* ✨ migration init scripts are now complete
- 1. add tables
- 2. add fixtures
- 3. add default settings
* 🎨 important: make bootup script smaller!
- remove all TODO'S except of one
- no seeding logic in bootup script anymore 🕵🏻
* ✨ sephiroth: allow params for init command
- param: skip (do not run this script)
- param: only (only run this script)
- very simple way
* 🎨 adapt tests and test env
- do not use migrate.populate anymore
- use sephiroth instead
- jscs/jshint
* 🎨 fix User model status checks

3. error creation (which will be part of PR #7477)
- ✨ add express error handler for html/json
- one true error handler for express responses
- contains still some TODO's, but they are not high priority for first implementation/integration
- this middleware only takes responsibility of either rendering html responses or return json error responses
- 🎨 use new express error handler in middleware/index
- 404 and 500 handling
- 🎨 return error instead of error message in permissions/index.js
- the rule for error handling should be: if you call a unit, this unit should return a custom Ghost error
- 🎨 wrap serve static module
- rule: if you call a module/unit, you should always wrap this error
- it's always the same rule
- so the caller never has to worry about what comes back
- it's always a clear error instance
- in this case: we return our notfounderror if serve static does not find the resource
- this avoid having checks everywhere
- 🎨 replace usages of errors/index.js functions and adapt tests
- use logging.error, logging.warn
- make tests green
- remove some usages of logging and throwing api errors -> because when a request is involved, logging happens automatically
