What's the most efficient way to increase a PositiveIntegerField in a view in Django?
I have a model with this field in models.py: vote_submissions = models.PositiveIntegerField() In the view, I originally just did a basic object.vote_submissions += 1 object.save() return HttpResponseRedirect(reverse('index')) as I am still learning the in's and out's of Django. From what I understand I should use F() expression? I have this in my views.py and it works (not tested yet). from django.db.models import F Category.objects.filter(id=object.id).update( vote_submissions=F('vote_submissions') + 1) return HttpResponseRedirect(reverse('index')) Is this the most efficient and safest way to do these kind of updates? Thank you. -
How to pass data to a serializer using Requests module in Django?
I want to create a registration form that allows me sign up. Instead of saving the form usually (by using Django forms), I have created an API that obtains all the data from the form and save it to the model. I have tried this method but I am not getting any results: models.py: from django.contrib.auth.models import User class Profile(models.Model): user = models.OneToOneField(User, on_delete = models.CASCADE, primary_key=True, related_name = 'profile') address = models.TextField() phoneno = models.IntegerField() views.py: def signup(request): if request.method == 'POST': user_form = UserForm(request.POST) register_form = RegisterForm(request.POST) if user_form.is_valid() and register_form.is_valid(): username = request.POST.get("username", ""), first_name = request.POST.get("first_name",""), last_name=request.POST.get("last_name",""), email=request.POST.get("email",""), password=request.POST.get("password2",""), address=request.POST.get("address",""), phoneno=request.POST.get("phoneno","") payload = { 'username': username, 'first_name': first_name, 'last_name': last_name, 'email':email, 'password':password, "profile" : { 'address': address, 'phoneno': phoneno, } } response = requests.post('http://127.0.0.1:8000/sign_api/',data=payload) serializer = UserSerializer(data=payload) if serializer.is_valid(): serializer.save() return redirect("login") else: user_form = UserForm() register_form = RegisterForm() return render(request, 'users/register.html', {'user_form': user_form, 'register_form': register_form}) class RAPI(APIView): permission_classes = [AllowAny] def post(self, request, format=None): serializer = UserSerializer(data=request.data) if serializer.is_valid(): serializer.save() content = {'status': 'You are registered'} return Response(content, status=status.HTTP_201_CREATED) return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST) serializers.py: class RegisterSerializer(serializers.ModelSerializer): class Meta: model = Profile fields = ('address','phoneno','department', 'salary') class UserSerializer(serializers.ModelSerializer): profile = RegisterSerializer() class Meta: model = User fields … -

How does django know which registered model to look through when displaying custom headings using list_display?
Take the following example class Adult (models.Model): age = models.IntegerField() class Minor (models.Model): age = models.IntegerField() Now I register both of them @admin.register(Adult,Minor) class AdultAdmin(admin.AdminModel): list_display = ('age') class MinorAdmin(admin.AdminModel): list_display = ('age') Now when viewing the entries via the admin page, will the distinction be made according to the class names, or will django go through all models in a specific order to see if that model has the mentioned field. If it's the former, then does that mean that the class name has to be in a specific format - the model name followed by the word 'Admin' ? -

Django Creating constraints on serializers
I'm trying to extend Django's Poll app. Each poll will have 2 choices and either an image for each choice or a color for each choice, but not both. My models look like this: class Question(models.Model): question = models.CharField() created_at = models.DateTimeField(auto_now_add=True) class Choice(models.Model): question = models.ForeignKey(Question, on_delete=models.CASCADE) choice = models.CharField(max_length=120) vote_count = models.IntegerField(default=0) class ChoiceImage(models.Model): choice = models.OneToOneField(Choice, on_delete=models.CASCADE) img = models.ImageField() class ChoiceColor(models.Model): choice = models.OneToOneField(Choice, on_delete=models.CASCADE) color = models.CharField(max_length=7) I have a View that looks like this: class CreateQuestionView(CreateAPIView): serializer_class = CreateQuestionSerializer With the following serializers: class ChoiceImageSerializer(serializers.ModelSerializer): class Meta: model = ChoiceImage fields = ('image',) class ChoiceColorSerializer(serializers.ModelSerializer): class Meta: model = ChoiceColor fields = ('color',) class ChoiceSerializer(serializers.ModelSerializer): choice_image = ChoiceImageSerializer(many=False) choice_color = ChoiceColorSerializer(many=False) class Meta: model = Choice fields = ('choice', 'choice_image', 'choice_color') class CreateQuestionSerializer(serializers.ModelSerializer): choices = ChoiceSerializer(many=True) class Meta: model = Question fields = ('question', 'choices') How do I create this constraint on my serializers? Also Am I designing this efficiently or is there a better way to do this? -

Automatically render None as null in template?
I am rendering a template with message bundled in the context. Sometimes the message will be None: def context_test(request): context = { 'message': None, } return render(request, 'testapp/context_test.html', context) I want to alert the message on front-end only if it is not None. So far I am doing it like this: <!DOCTYPE HTML> <html> <head> </head> <body> </body> <script> let message = "{{ message }}" {% if message %} alert(message) {% endif %} </script> </html> However, I would like to replace the Django's if clause with pure Javascript, like so: <!DOCTYPE HTML> <html> <head> <style> </style> </head> <body> </body> <script> let message = "{{ message }}" // or {{ message }} ? if (message) { alert(message) } </script> </html> In order for this to work, I would need message equal to null (or other falsy value) in the script. Can it be done in a clean way, without an additional conversion in the script like if {message === 'None'} message = null? In other words, can I somehow tell Django to automatically render context's None as null in the template? -

What is wrong with my Gulp Watch task with Docker?
I'm trying to run a gulp watch task in my dockerfile and gulp isn't catching when my files are getting changed. Quick Notes: This set up works when I use it for my locally hosted wordpress installs The file changes reflect in my docker container according to pycharm's docker service Running the "styles" gulp task works, it's just the file watching that does not It's clear to me that there's some sort of disconnect between how gulp watches for changes, and how Docker is letting that happen.

Show a drop down in django form
I am creating a django form which consists of a field that is related with another model via Foreign Key. Originally it is showing a dropdown of all the instances from the related model but I want to show only those fields which are connected with the user for that I am using this code.
