Json-API in combination of django-rest-framework-jwt

In my unit tests, when I do a post, I get the following error:

======================================================================
ERROR: test_get_one_vehicletype_in_french (masterdata.tests.VehicleTypeTest)
----------------------------------------------------------------------
Traceback (most recent call last):

    view = context.get('view')
AttributeError: 'NoneType' object has no attribute 'get'

If you look at the last three steps in the trace, there is ret = renderer.render(data) which calls rest_framework_json_api.JSONRenderer.render without a renderer_context argument. It then passes None (default value) to rest_framework_json_api.utils.get_resource_name where it tries to call view = context.get('view') on None… which of course can’t work.

My DRF settings:

REST_FRAMEWORK = {
    'PAGINATE_BY': 30,
    'PAGINATE_BY_PARAM': 'page_size',
    'MAX_PAGINATE_BY': 100,

I think I have a content negotiation problem, since the JWT data should be plain json and the api data jsonapi.

Depending on the order of of the parsers and renderers in settings.py (I currently have both, rest_framework.renderers/parsers and rest_framework_json_api.renderers/parsers) and accept headers I can either get

• all of my unit tests working but not the JWT-Auth request (testing with curl) or
• the JWT-Auth-Request but not the unit tests except the get requests

working.

Since you’re saying “I prefer to submit and retrieve jwt related stuff in the application/json format.” I suspect you know the correct combination of configuration and Accept headers (maybe content-type too?) 😃

Sorry for being a bit off topic here.

Sorry, yes!
