Django add a product to the user automatically
I want to add a product to the user profile, but I can only do it by using a form, and on the template choosing the user from a dropdown menu. What I want to do, is, go to add product ('Añadir vehiculo' in this case), and select the features of said product on the fields, and then I want that product to be automatically added to my profile. As you can see in this image, where it says "Propietario" it's the user(client). https://imgur.com/hWZntVQ And I want to make this: https://imgur.com/VGWUYiv Select every single field but not the "Propietario"(client) one, so It's automatically added to the user who is adding it. But I get these two errors when I change a couple of things, and I can't think of a way to make this work.

How can I show a dropdown in my form with the title of the objects in the table? Django ModelForm
Hi I've been trying to create a simple app for workflows or binary protocols (yes or no instructions, very helpful sometimes) I have created a simple form with ModelForm: class BlocForm(forms.ModelForm): class Meta: model = Bloc fields = [ 'description', 'loop_child' ] and my model looks like this: class Loopeable(models.Model): protocol = models.ForeignKey(Protocol, on_delete=models.CASCADE, null=True) description = models.TextField() pointing_at = models.IntegerField() class Bloc(models.Model): description = models.TextField() protocol = models.ForeignKey(Protocol, on_delete=models.CASCADE) parent = models.ForeignKey('self',on_delete=models.CASCADE, null=True, blank=True) loop_child = models.ForeignKey(Loopeable, on_delete=models.CASCADE, null=True, blank=True) question = models.BooleanField(default=False) end_bloc = models.BooleanField(default=False) And my problem is that instead of having this loop_chile dropdown list of ugly objects I would like to get the description in the Loopeable Model, is there a way to get some data that is not just "Loopeable Object (id_number)". I didn't add my views.py in order to keep the post short, but I implemented the for by simply doing something like: form = BlocForm(request.POST or None) if form.is_valid(): ...rest of the code If anyone has some ideas I will be grateful!! Thanks... -
Creating dropdown like Django Admin

Cannot change django auth urls namespace
I'm including all Django auth urls in one go, like this: app_name = "main" urlpatterns = [ ... path("accounts/", include("django.contrib.auth.urls")), ... ] However, if I go to /accounts/password_reset/ and add my email, the email gets sent but it can't resolve the "reset done" url. Error: NoReverseMatch at /accounts/password_reset/ Reverse for 'password_reset_done' not found. 'password_reset_done' is not a valid view function or pattern name. I assume the reason is that it is resolvable at "main:password_reset_done". Then I add a namespace in my url include like this: app_name = "main" urlpatterns = [ ... path("accounts/", include("django.contrib.auth.urls", namespace="main")), ... ] But then I get another error: django.core.exceptions.ImproperlyConfigured: Specifying a namespace in include() without providing an app_name is not supported. Set the app_name attribute in the included module, or pass a 2-tuple containing the list of patterns and app_name instead. Which doesn't make sense, as I already have app_name set. -

PasswordChangeForm from Django doesnt show on template
I'm tying to make a ChangePasswordForm but it isn't showing on template. The section only prints the description but it doesnt show the form. By the way, Ive been reading about that specific form, and most websites claim it to be implemented by Django, thats why i hadn't put it on forms. I think that might be the mistake. views.py def change_password_view(request): if request.method == 'POST': form = PasswordChangeForm(request.user, request.POST) if form.is_valid(): user = form.save() update_session_auth_hash(request, user) # Important! messages.success(request, 'Contraseña cambiada con éxito') return redirect('profileedit') else: messages.error(request, 'Ha ocurrido un error.') else: form = PasswordChangeForm(request.user) context = { 'form2': form } return render(request, 'profileedit.html', context) template (in case of) <form method="POST" action="#" id="contraForm" name="form2"> {% csrf_token %} <p>Por favor, llena los siguientes campos para cambiar tu contraseña. {{ form2.as_ul }} <button class="btn btn-primary py-1 px-2" type="submit" > Save </button> </p> </form> -
Base64ImageField for Django Nested Serializer
I have a model that looks like this: class ChoiceImage(models.Model): choice = models.OneToOneField(Choice, on_delete=models.CASCADE, null=True) img = models.ImageField(upload_to='some-path/') That points to: class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice = models.CharField(max_length=120) vote_count = models.IntegerField(default=0) When a user submits a Question, it goes through this serializer: class CreateQuestionSerializer(serializers.ModelSerializer): choice_set = CreateChoiceSerializer(many=True) class Meta: model = Question fields = ('user', 'choice_set') def create(self, validated_data): choices_validated_data = validated_data.pop('choice_set') question = Question.objects.create(**validated_data) choices_serializer = self.fields['choice_set'] for choice in choices_validated_data: choice['question'] = question choices_serializer.create(choices_validated_data) return question Then this: class CreateChoiceSerializer(serializers.ModelSerializer): choiceimage = ChoiceImageSerializer(many=False, required=False) class Meta: model = Choice fields = ('choice', 'choiceimage') def create(self, validated_data): image_uploaded = validated_data.get("choiceimage") image_validated_data = validated_data.pop('choiceimage') choice = Choice.objects.create(**validated_data) image_serializer = self.fields['choiceimage'] image_validated_data['choice'] = choice image_serializer.create(image_validated_data) class ChoiceImageSerializer(serializers.ModelSerializer): img = Base64ImageField() class Meta: model = ChoiceImage fields = ('img',) Notice how I have Base64ImageField() as my img. Whenever I submit data in my form, it complains saying no file was submitted. However, I'm submitting a Base64Image I'm not sure why it's complaining about a file when I'm specifying that it'll be a Base64ImageField What am I doing wrong? -

Traverse multiple foreign keys in Django DetailView
I'm working on a project to record all scores shot at a bunch of archery events. They are shot by many people at many events and many different archery rounds. (A "round" in archery is a particular type of competition. For the sake of simplicity let's say there are two: indoor and outdoor.) Here's a basic ER diagram of the relevant part of my database model: ┌───────────┐ ┌───────────┐ ┌────────────────┐ ┌───────────┐ │ │ ╱│ │╲ │ │╲ │ │ │ Person │──────┼──│ Score │──┼────│ EventRound │──┼─────│ Event │ │ │ ╲│ │╱ │ │╱ │ │ └───────────┘ └───────────┘ └────────────────┘ └───────────┘ ╲│╱ ┼ │ ┌───────────┐ │ │ │ Round │ │ │ └───────────┘ You can see that there are two ManyToMany relationships at work here resolved with two junction tables (EventRound and Score).

This is my post_create view: @login_required def post_create(request): data = dict() if request.method == 'POST': form = PostForm(request.POST) if form.is_valid(): post = form.save(False) post.author = request.user #post.likes = None post.save() data['form_is_valid'] = True posts = Post.objects.all() data['posts'] = render_to_string('home/posts/home_post.html',{'posts':posts}) else: data['form_is_valid'] = False else: form = PostForm context = { 'form':form } data['html_form'] = render_to_string('home/posts/post_create.html',context,request=request) return JsonResponse(data) This is my post.js for handling Ajax: $(document).ready(function(){ var ShowForm = function(){ var btn = $(this); $.ajax({ url: btn.attr("data-url"), type: 'get', dataType:'json', beforeSend: function(){ $('#modal-post').modal('show'); }, success: function(data){ $('#modal-post .modal-content').html(data.html_form); } }); return false; }; var SaveForm = function(e){ e.preventDefault(); var form = $(this); $.ajax({ url: form.attr('data-url'), data: form.serialize(), type: form.attr('method'), dataType: 'json', success: function(data){ if(data.form_is_valid){ $('#post-list div').html(data.posts); $('#modal-post').modal('hide'); } else { $('#modal-post .modal-content').html(data.html_form) } } }) return false; } //create $('.create-post-btn').click(ShowForm); $('#modal-post').on("submit",".post-create-form",SaveForm) //update $('#post-list').on("click",".show-form-update",ShowForm); $('#modal-post').on("submit",".update-form",SaveForm) //delete $('#post-list').on("click",".show-form-delete",ShowForm); $('#modal-post').on("submit",".delete-form",SaveForm) }); And this is my post model: class Post(models.Model): title = models.CharField(max_length=100) content = models.TextField(validators=[MaxLengthValidator(250)]) author = models.ForeignKey(Profile, on_delete=models.CASCADE) date_posted = models.DateTimeField(auto_now_add=True) last_edited= … -
No module named 'registration' in django 2.2.5
I am using django 2.2.5 with python 3.6 i have installed django-registration by adding it to my project's installed apps and then doing a pip install django-registration. All this worked fine but now when i am trying to perform a python mange.py makemigrations am getting this error. I read a lot of solutions online and they don't seem to work, i tried downgrading the django-registration version to 2.4 but then it uninstall django 2.2.5 because it works with django 1, which will cause some other serious problems. here is my installed app section: INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'registration', 'wewriteapp', 'crispy_forms', ] Traceback (most recent call last): File "manage.py", line 21, in <module> main() File "manage.py", line 17, in main execute_from_command_line(sys.argv) File "C:\Users\Ahmed\Anaconda3\lib\site-packages\django\core\management\__init__.py", line 381, in execute_from_command_line utility.execute() File "C:\Users\Ahmed\Anaconda3\lib\site-packages\django\core\management\__init__.py", line 357, in execute django.setup() File "C:\Users\Ahmed\Anaconda3\lib\site-packages\django\__init__.py", line 24, in setup apps.populate(settings.INSTALLED_APPS) File "C:\Users\Ahmed\Anaconda3\lib\site-packages\django\apps\registry.py", line 91, in populate app_config = AppConfig.create(entry) File "C:\Users\Ahmed\Anaconda3\lib\site-packages\django\apps\config.py", line 90, in create module = import_module(entry) File "C:\Users\Ahmed\Anaconda3\lib\importlib\__init__.py", line 127, in import_module return _bootstrap._gcd_import(name[level:], package, level) File "<frozen importlib._bootstrap>", line 1006, in _gcd_import File "<frozen importlib._bootstrap>", line 983, in _find_and_load File "<frozen importlib._bootstrap>", line 965, in _find_and_load_unlocked ModuleNotFoundError: No module named 'registration' -
Django request.user modification not happening in test
I have a view that is changing a field of request.user: def test(request): request.user.is_provider = False request.user.save() print(request.user.is_provider) return HttpResponse(status=200) Now I am testing the function and I have the following test: class RoleSwitchTests(TestCase): def test_switch_to_customer(self): User = get_user_model() user = User.objects.create_user( username='test', email='test', password='test', first_name='test', last_name='test', is_provider=True, is_admin=False, ) self.client.login(username='test', password='test') response = self.client.post('/test/', follow=True) print(user.is_provider) self.assertEqual(response.status_code, 200) self.assertFalse(user.is_provider) self.assertFalse(user.is_provider) fails here. For some reason, request.user.is_provider is False in test, but in test_switch_to_customer, user.is_provider is True. I know these refer to the same user because they have the same id, so why is the modification not being preserved here?
