Generate fake WSGIRequest objects for use in Django views

fake_request.py

def fake_request(method=None, fake_user=False):
    '''Returns a fake `WSGIRequest` object that can be passed to viewss.

    If `fake_user` is `True`, we attach a random staff member to the request.
    Even if not set, you can still do this manually by setting the `user`
    attribute on the returned object.

    The `GET` and `POST` `QueryDict` objects are mutable::

        req = fake_request(mutable=True)
        req.GET['q'] = 'abc'
        my_view(req)

    '''
    request = WSGIRequest({
        'REQUEST_METHOD': method or 'GET',
        'wsgi.input': StringIO(),
    })

    if fake_user:
        # Any staff member will do
        request.user = User.objects.filter(
            is_staff=True, is_active=True
        )[0]

    request.GET = QueryDict('', mutable=True)
    request.POST = QueryDict('', mutable=True)

    return request

better write from where to import StringIO()

from django.core.handlers.wsgi import WSGIRequest
from io import StringIO
from django.http import QueryDict
