RequestFactory does not have a trace method.

When testing for views, RequestFactory is very useful to get, post, put, patch, delete, head, options a view.

However trace is missing from RequestFactory even if it's allowed by django.views.generic.View.

A simple fix would be to add trace to RequestFactory.

Example (taken from the doc):

rf = RequestFactory()
get_request = rf.get('/hello/')
post_request ='/submit/', {'foo': 'bar'})

I have one case where I'm extending django.views.generic.View and where I'm only allowing dispatch
to only use get and I've written a test to check this condition.


My view:

from django.views.generics import View

class CustomView(View):
    http_method_names = ('get',)

My test:

from django.test import RequestFactory, TestCase

class TestCustomView(TestCase):
    method_not_allowed = (

    def test_method_not_allowed(self):
        url = '/'
        for method in method_not_allowed:
            with self.subTest(method=method):
                request = getattr(RequestFactory(), method)(url)
                self.assert(status_code, 405)

The previous test when hit return the following error:

Traceback (most recent call last):
  File "", line 85, in test_method_not_allowed
    request = getattr(RequestFactory(), method)(url)
AttributeError: 'RequestFactory' object has no attribute 'trace'

The trace() method was not implemented in RequestFactory, and the RequestFactoryTests suite was testing just the GET requests.

I have submitted , that implements the trace() method, extends the scope of the existing test suite for the RequestFactory, and adds a test for the new method.

The patch looks good (I just made a minor comment about using del ... instead of del(...)).

It just needs a mention in the release notes for 1.8 and we're good to go.

While I was adding the notes in the docs, I noticed that the django.test.Client, that subtypes the RequestFactory, does not implemenent the trace() method either. We would probably need to implement this method in the test client also.

What is the suggested course of action?
