用于FormView的Django错误405

Question

在测试期间遇到FormView问题。我有以下测试：

def test_reviewform_contact(self):
    data = {
        'user': self.u2.pk,
        'product': self.r1.pk,
        'rating': 5,
        'title': "I turn to see my dream",
        'content': "This reward was joocy as FUARK."
        }
    response = self.client.post(reverse('reviews:reviewreward'), data)
    location = "http://testserver%s?next=%s" % (reverse('affiliates:onboarding_contact'), reverse('reviews:reviewreward'))
    self.assertEqual(response.status_code, 302)
    self.assertEqual(response['Location'], location)

该视图有一个装饰器，用于检查用户是否通过测试，如果没有，则重定向。一个简单的user_passes_test函数，已经过测试，可以在不同的表单/表单视图上工作。表格已经过测试并通过了每项测试。有问题的观点：

class ReviewFormView(FormView):
    template_name = "general/processing.html"
    form_class = ReviewForm
    success_url = reverse_lazy('offers:dashboard')

    def render_to_json_response(self, context, **response_kwargs):
        data = json.dumps(context)
        response_kwargs['content_type'] = 'application/json'
        return HttpResponse(data, **response_kwargs)

    def form_invalid(self, form):
        response = super(ReviewFormView, self).form_invalid(form)
        if self.request.is_ajax():
            t = "We're having some problems saving your review..."
            m = form.errors
            message = render_to_string('reviews/error-alert.html', {'title':t, 'messages':m})
            data = { 'messages': message }
            return self.render_to_json_response(data, status=400)
        else:
            return response

    def form_valid(self, form):
        response = super(ReviewFormView, self).form_valid(form)
        review = form.save()
        if self.request.is_ajax():
            data = {
                'pk': review.id,
                'title': review.title,
            }
            return self.render_to_json_response(data, status=200)
        else:
            return response

    @method_decorator(active_and_login_required)
    def dispatch(self, *args, **kwargs):
        return super(ReviewFormView, self).dispatch(*args, **kwargs)

Urlconf以防万一：

from django.conf.urls import patterns, include, url
from reviews.views import *

urlpatterns = patterns('',
    url(r'^review-opinion/$', ReviewHelpfulView.as_view(), name="reviewlike"),
    url(r'^review-reward/$', ReviewFormView.as_view(), name="reviewreward"),
)

我得到了，标题中描述的错误405。不确定该方法有什么问题。有什么帮助吗？
