django-rest-framework http put failing with 415 on django 1.5

You're absolutely on the right track - the breaking test in that case is certainly due to Django's change in PUT behavior for the test client.

Your fix looks right to me, too. 415 is the "Unsupported Media Type" response, which means that the request content type wasn't something that could be handled by any of the parsers configured for the view.

Normally in case like this, that'd be due to forgetting to set the content type of the request, but it looks like you've got that correctly set to multipart/form-data; boundary=...

Things to double check:

• Exactly what does response.data display as the error details?
• What do you have configured in you DEFAULT_PARSER_CLASSES setting, if you have one, or what do you have set on the view attribute parser_classes if it has one?
• Make sure there's not a typo in content_type in the test (even though it's correct here).

Edit:

Thanks for your comments - that clears everything up. You've only got the JSON parser installed, but you're trying to send Form encoded data. You should either:

• Add FormParser and MultiPartParser to your settings/view, so that it supports form encodings. (Note also that the default DEFAULT_PARSER_CLASSES setting does include them, so if you don't set anything at all it'll work as expected)

Or

• Encode the request using json encoding, not form encoding... data=json.dumps(prepare_dict(self.account)), content_type='application/json' in your test case.

Got a 415 error because I used an instance of django.test import Client instead of rest_framework.test import APIClient. APIClient will encode the data automatically in it's right way.

Pure json request:

client = APIClient()
client.post(url, format='json', data=json, headers=headers)
client.put(url, format='json', data=json, headers=headers)

Create/Update including file(s):

client = APIClient()
client.post(url, format='multipart', data=data, headers=headers)
client.put(url, format='multipart', data=data, headers=headers)

I spent a lot of time with this 415 error, so I hope this helps anyone else.
