allauth Reverse for 'login' not found. 'login' is not a valid view function or pattern name
I am using allauth and have my login/logout functionality working properly on the site (I can login/logout/register successfully in Selenium functional tests aswell). My problem is when I try to do unit tests to check the correct templates are being used for any view with the @login_required decorator. For example: View: @login_required def profile(request): return render(request, 'users/profile.html') Unit test: class ProfileTest(TestCase): def test_uses_profile_template(self): # it makes no difference if this is commented out or not #class MockUser: # is_authenticated = True response = self.client.get('/users/profile') #response.user = MockUser() self.assertTemplateUsed(response, 'profile.html') My urls: path('accounts/', include('allauth.urls')), And the error msg: NoReverseMatch: Reverse for 'login' not found. 'login' is not a valid view function or pattern name My biggest confusion comes from the fact everything works fine in functional tests and when using the site normally. Thank you. -

Data Dissapearing in Django on validation

Share class instance between two clients (python)
I'm building a very simple multiplayer web game. It's tron lightcycles, but to turn, the user must solve an arithmetic problem.

I have tried another method to create a like button for posts, I have reached to the phase where button directs me to an error of This page isn’t working Not sure where the problem relies on. I am following a tutorial but the only difference is that the tutorial created a function for the post with context in the views while I created a class for the post. I don't know if this is the reason for some deviations and the error appearing Here is the Model: class Post(models.Model): designer = models.ForeignKey(User, on_delete=models.CASCADE) title = models.CharField(max_length=100) likes = models.ManyToManyField(User, blank=True, related_name='liked') def __str__(self): return self.title def get_absolute_url(self): return reverse("score:post-detail", kwargs={'pk': self.pk}) @property def num_likes(self): return self.liked.all().count() LIKE_CHOICES = ( ('Like', 'Like'), ('Unlike', 'Unlike'), ) class Like(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE) post = models.ForeignKey(Post, on_delete=models.CASCADE) value = models.CharField(choices=LIKE_CHOICES, default='Like', max_length=10) def __str__(self): return str(self.post) here is the views class PostListView(ListView): model = Post template_name = "score.html" ordering = ['-date_posted'] context_object_name = 'posts' queryset = Post.objects.filter(admin_approved=True) paginate_by = 5 def like_post(request): user = request.user if request.method == 'Post': post_id = request.POST.get('post_id') post_obj = Post.objects.get(id=post_id) if user in post_obj.liked.all(): post.obj.liked.remove(user) else: post_obj.liked.add(user) like, created = Like.objects.get_or_create(user=user, post_id=post_id) if not created: if like.value … -
What is the best data schema for “like, dislike, inappropriate-content-report” in Django
I have a project for a forum. The forum has limitless posts and comments. I want to make “like, dislike, report inappropriate content” model. I am a meticulous person and I have 3 options. These 3 options are: 1- create three different models as follow: class Like(models.Model): ''' like comment ''' comment = models.OneToOneField(Comment, related_name="likes", on_delete=models.CASCADE) users = models.ManyToManyField(User, related_name='requirement_comment_likes') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return str(self.comment.comment)[:30] class DisLike(models.Model): ''' Dislike comment ''' comment = models.OneToOneField(Comment, related_name="dis_likes", on_delete=models.CASCADE) users = models.ManyToManyField(User, related_name='requirement_comment_dis_likes') created_at = models.DateTimeField(auto_now_add=True) updated_at = models.DateTimeField(auto_now=True) def __str__(self): return str(self.comment.comment)[:30] Please look at this thread This is easy to implement.

This will result in bigger table. class Post(models.Model): user = models.ForeignKey(User, on_delete=models.CASCADE, verbose_name="Пользователь", related_name='author') title = models.CharField(max_length=80, verbose_name="Название") body = models.TextField(verbose_name="Текст публикации") created = models.DateTimeField(auto_now_add=True, verbose_name="Дата создания") modified = models.DateTimeField(auto_now=True, verbose_name="Дата обновления") description = models.CharField(max_length=400,verbose_name = "Описание") reading_time = models.PositiveSmallIntegerField(verbose_name="Время для чтения в минутах") likes = models.PositiveIntegerField(default=0) dislikes = models.PositiveIntegerField(default=0) users_reaction = models.ManyToManyField(User, blank=True, verbose_name='Реакция юзеров', related_name='react') Please note that in here they …
