Question

我正在尝试在Django中基于函数的视图上做一个TestCase，我得到了： AssertionError：200！= 302：响应未按预期重定向：响应代码为200（预期为302）错误。该视图就像博客项目中的帖子一样，我认为我的帖子发布方式有误，但我不了解如何以正确的方式进行测试。

This is my related views:

## view where the button like appears
class PostDetailView(FormMixin, generic.DetailView):
    model = Post
    form_class = CreateComments

    def get_success_url(self):
        return reverse('post-detail', kwargs={'pk': self.object.id})

    def get_context_data(self, **kwargs):
        context = super(PostDetailView, self).get_context_data(**kwargs)
        actual_post = get_object_or_404(Post, id=self.kwargs['pk'])
        liked = False
        if actual_post.likes.filter(id=self.request.user.id).exists():
            liked = True

        context['total_likes'] = actual_post.total_likes()
        context['liked'] = liked
        context['form'] = CreateComments()

        return context

    def post(self, request, *args, **kwargs):
        self.object = self.get_object()
        form = self.get_form()
        if form.is_valid():
            return self.form_valid(form)
        else:
            return self.form_invalid(form)

    def form_valid(self, form):
        form.instance.author = self.request.user
        form.instance.blog_post = get_object_or_404(Post, pk=self.kwargs['pk'])
        form.save()
        return super(PostDetailView, self).form_valid(form)

# related model:
class Post(models.Model):

    """Model representing a blog post"""
    title = models.CharField(max_length=200, help_text='Enter a post title')
    description = models.TextField(max_length=1000, help_text='Enter a description for the post')
    date = models.DateTimeField(default=timezone.now)

    author = models.ForeignKey(User, on_delete=models.CASCADE)
    likes = models.ManyToManyField(User, related_name='blog_post')

    def total_likes(self):
        return self.likes.count()

    def __str__(self):
        """String for representing the Model object"""
        return self.title

    def get_absolute_url(self):
        """Returns the url to acces a detail record for this book"""
        return reverse('post-detail', kwargs={'pk': self.pk})


## view of the proper like:

def LikeView(request, pk):
    post = get_object_or_404(Post, id=request.POST.get('post_id'))

    liked = False
    if post.likes.filter(id=request.user.id).exists():
        post.likes.remove(request.user)
        liked = False
    else:
        post.likes.add(request.user)
        liked = True
    return HttpResponseRedirect(reverse('post-detail', args=[str(pk)]))

## urls.py

path('post/like/<int:pk>/', LikeView, name='like-post'),

## test with error:

    def test_likes(self):
        login = self.client.login(username='user1', password='user1senha')
        post = self.client.get(reverse('post-detail', kwargs={'pk': '1'}))
        response = self.client.post(reverse('post-detail', kwargs={'pk': '1'}), post.context['object'].likes.add(post.context['user']))
        self.assertEqual(response.context['total_likes'], 1)

    def test_likes_redirects_to_correct_template(self):
        login = self.client.login(username='user1', password='user1senha')
        post = self.client.get(reverse('post-detail', kwargs={'pk': '1'}))
        response = self.client.post(reverse('post-detail', kwargs={'pk': '1'}), post.context['object'].likes.add(post.context['user']))
        self.assertRedirects(response, reverse('post-detail', kwargs={'pk': '1'}))

在这些测试中，我要添加类似内容，但assertRedirects失败，请帮助我！

Answer 1

我认为您的帖子没有返回您的期望。我建议在调试器中查看响应（或只在assertRedirects语句前面使用print（response））。帖子发布期间可能有错误。

好消息是该测试可能会按设计工作。

如何测试基于功能的视图？
