UUID fails unit pytest due to formatting?
I am returning a user's UUID in my serializier and this works fine. However, when writing a unit test to test this return the test fails despite them being called the same way. Below is a simplified version of my code. My serializers.py: class UserSerializer(serializers.ModelSerializer): user_sso = serializers.SerializerMethodField("get_user_sso") class Meta: model = get_user_model() fields = ( "user_sso", ) def get_user_sso(self, user): return user.profile.sso_id My unit test in test_views.py class TestUserAPIView(BaseAPIViewTest): factory = factories.UserFactory def expected_response(self, user): return { "user_sso": user.profile.sso_id, } The failed test message (the user generated from a factory is the top one): E - 'user_sso': UUID('f696d740-bdd5-43a3-8f58-406b7a1e117d')}, E ? ----- - E + 'user_sso': 'f696d740-bdd5-43a3-8f58-406b7a1e117d'}, How do I make this test pass? I do not have the word 'UUID(' at the begining of my current output which looks to be the problem but I'm not sure how to remove this without everything a string? Many thanks. -

Combining DetailView and CreateView in Django 3.2/4.0, as explained in the docs
I'm building a generic blog and trying to enable users to make comments directly on the article page. I am trying to implement this by combining DetailView with CreateView. The docs present 3 different solutions to this issue: FormMixin + DetailView: this is the answer that Django docs advise against, but that is advised by most answers on SO that I could find DetailView only + write the post method: "a better solution" according to Django docs DetailView + FormView: "an alternative better solution", and the one I'm trying to implement. The "alternative better" solution consists in making a DetailView for articles and a FormView for comments, but the docs state that "This approach can also be used with any other generic class-based views", which means that DetailView + CreateView should be possible. I've gone through a number of SO items that reference this solution, but I am unable to implement any of them. This SO question suggests mixing DetailView and CreateView. However, the explanation in that answer is incomplete. Another SO question, among advice to use FormMixins, has this answer that is close, but different. Other questions (1, 2, etc.) only address the FormMixin and DetailView + post methods. … -

Creating Multible IDs for multible Buttons in one <Input> Tag
I'm working on a TicTacToe game using Django/Djangotemplates, Python and a bit Javascript. I've come across a problem tho. i only have one Button which is for-looped 9 times. its ID is its index. Now I'm not certain how to add the {{index}} which i defined in the for loop in the javascript onclick function. here the html template <div class="grid-container"> {% for index in object.board %} <div class="grid-item"> <input onclick="change(button.id)" class="buttonsize btn-outline-purple" type="submit" value="" name="button" id="{{index}}"> </div> {% endfor %} </div> </div> </article> </form> <script> function change(inputid){ console.log("test") var elem = document.getElementById(inputid); if (elem.value=="") elem.value = "X" } </script> here the models.py class TicTacToe(models.Model): player1 = models.ForeignKey(User, on_delete=models.CASCADE, default="X", related_name="tictactoe_as_player1") player2 = models.ForeignKey(User, on_delete=models.CASCADE, default="O", related_name="tictactoe_as_player2") current_player = models.ForeignKey(User, on_delete=models.CASCADE, related_name="tictactoe_current_player") title = models.CharField(max_length=100) board = models.CharField(max_length=9, default="012345678") def __str__(self): return self.title def get_absolute_url(self): return reverse('tictactoe-detail', kwargs={'pk': self.pk}) and here the views.py class TicTacToeCreateView(LoginRequiredMixin, CreateView): model = TicTacToe template_name = 'website/newgame_form.html' fields = ['player1', 'player2', 'current_player', 'title', 'board'] def form_valid(self, form): form.instance.author = self.request.user return super().form_valid(form) class TicTacToeDetailView(UpdateView): model = TicTacToe fields = ['player1', 'player2', 'current_player', 'title', 'board'] def clean(self): if 'button0' in self.data: print('button0') i also got a database but there is really not much in there except … -
File Uploading in deployed Django applications
Where to store the images when a Django application is deployed through "Heroku" if I need to upload images using the same application after deployment ?
