Django Rest Framework APIRequestFactory request object does not have attribute 'query_params'

Question

Suppose I have this APIView

class Dummy(APIView): def get(self, request): return Response(data=request.query_params.get('uuid')) 

To test it, I need to create a request object to go to the get function

 def test_dummy(self): from rest_framework.test import APIRequestFactory factory = APIRequestFactory() request = factory.get('/?uuid=abcd') DummyView().get(request) 

He complains about AttributeError: 'WSGIRequest' object has no attribute 'query_params'

Looking in more detail, the factory creates an instance of WSGIRequest instead of the DRF version <class 'rest_framework.request.Request'> .

 >>> from rest_framework.test import APIRequestFactory >>> factory = APIRequestFactory() >>> request = factory.get('/') >>> request.__class__ <class 'django.core.handlers.wsgi.WSGIRequest'> 

Answer 1

It is right. Currently, APIRequestFactory returns an HttpRequest object that only updates to the REST framework Request object when it reaches the presentation level.

This reflects the behavior that you see in a real request, and what it does is, for example, a matter. rendering JSON, XML, or any other type of content that you customized for your test requests.

However, I agree that this is an amazing behavior, and at some point it will probably return a Request object, and presenting the REST structure will ensure that it will perform a Request update on requests for HttpRequest instances.

What you need to do in your case is actually to call the view, and not invoke the .get() method ...

 factory = APIRequestFactory() request = factory.get('/?uuid=abcd') view = DummyView.as_view() response = view(request) # Calling the view, not calling `.get()` 

Answer 2

Refer to Tom's solution, DummyView()(request) will DummyView()(request) error:

 TypeError: 'DummyView' object is not callable 

Instead, use as_view just like you do in urls.py :

 DummyView.as_view()(request) 

DRF as_view uses the initialize_request method to convert a Django Request object to a DRF version. You can try:

 from rest_framework.views import APIView APIView().initialize_request(request) >>> <rest_framework.request.Request object at 0xad9850c> 

You can also use APIClient to run the test. It also checks for URL submissions.

 from rest_framework.test import APIClient client = APIClient() client.post('/notes/', {'title': 'new idea'}, format='json')

I understand that this answer is some time after the question was asked, but it solved this problem for me. Just override the APIRequestFactory class as APIRequestFactory below.

 # Override APIRequestFactory to add the query_params attribute. class MyAPIRequestFactory(APIRequestFactory): def generic(self, method, path, data='', content_type='application/octet-stream', secure=False, **extra): # Include the CONTENT_TYPE, regardless of whether or not data is empty. if content_type is not None: extra['CONTENT_TYPE'] = str(content_type) request = super(MyAPIRequestFactory, self).generic( method, path, data, content_type, secure, **extra) request.query_params = request.GET return request
