Schemas & client libraries. #4179

tomchristie · 2016-06-08T13:30:07Z

Support for schema generation & dynamic client libraries.

See the new tutorial section, schema documentation, and api client documentation.

Needed to complete tutorial 7:

Graceful behavior with or without Core API installed.
Add --auth basic support to Core API.
Check permissions on schema generation.
Include pagination parameters in automatic schemas.

Other work as part of this, prior to 3.4.0 release.

Include filter parameters in automatic schemas.
Schema documentation.
Handle Document, Error and Link in JSON renderer?
Handle ListSerializer and other non-form.
Handle multipart vs json and/or other encodings.
Tests.
Handle text downloads.
Client library documentation.
Add coreapi to list of optional packages on homepage.

Moved to separate tickets:

Easier overrides on SchemaGenerator
Document using OpenAPI and other schema formats.
Move alternate formats in coreapi into separate packages. (HTML, OpenAPI, HyperSchema, HAL...)

Deferred:

~~Handle binary downloads.~~ Not strictly required for 3.4
~~Use id not pk in schema representations or change serializer representations?~~ Not strictly required for 3.4
~~Add to quickstart~~ Not strictly required for 3.4

…stalled.

Is there any reason why this couldn't be brought into the CoreJSONRenderer?

The problem is less what to do with CoreJSONRenderer and more about making sure that we preserve the behavior of that view for anything that isn't a schema renderer.

(Also I'd consider that part still slightly in flux - clearly needs refinement)

making sure that we preserve the behavior of that view for anything that isn't a schema renderer

Right, my main concern with that line (which I'm sure will probably change another few times before this is merged) is that it's hard-coding corejson as the only renderer with schema support.

Also I'd consider that part still slightly in flux - clearly needs refinement

Definitely understandable.

There was a move in 3.1 to remove features which had third-party dependencies from the core and put them into third-party packages that were still highly visible. See django-rest-framework-xml, django-rest-framework-yaml, and django-rest-framework-oauth for examples.

Is that still something we are pushing for?

Kinda. I see coreapi as a foundational thing here, so it's a bit different.

The various types of schema and docs that you can use it to generate will be third party, yup.
So eg we can have third party packages for schema formats: Swagger / API Blueprint / JSON Hyperschema, for docs templates driven by a coreapi.Document object, and for various hypermedia styles.

Using coreapi ensures that we're able to provide a common interface for all of those, so I don't have any great issues with pulling it in. If it's in core, then we're making the promise that it's an interface that is available to third-party devs, which should help drive folks making schema renderers / hypermedia renderers and docs renderers. Having said that, we could push for it to be third-party, if we wanted to, so I might be open to discussion.

"included in by" seems confusing. Maybe take out the "by"?

Good catch, that's a typo.

tomchristie · 2016-07-04T15:49:04Z

Remaining issues have now been split out into individual tickets.
Plan is to prepare up a 3.4.0 release, then resolve as many remaining tickets in the time remaining before Thursday 14th July, with a release planned on or before that date.

(Ensure it will be released prior to DjangoCon US, and give at least one clear working day to resolve any ciritical issues, post-release)

Yeah. Indeed.

Wouldn't it make more sense to use self.get_filter_class here?

Possibly, tho we don't actually have a queryset/model available to us at this point, so couldn't dynamically generate the filter class if none was set explicitly.

What are the problems with just calling view.get_queryset()?

Sure, that'd probably work okay.

DRF 3.4.7 is the same version run by edx/credentials. Release notes are at http://www.django-rest-framework.org/topics/release-notes/#34x-series. Highlights include: support for Django 1.10 (encode/django-rest-framework#4158 - sigh), support for schema generation (encode/django-rest-framework#4179 - required for newer versions of django-rest-swagger), and a change that prevents paginated views from re-running queries when count queries return 0 (encode/django-rest-framework#4201 - this explains the expected query count changes made in tests).
