Serializer for Players and their associated sessions
I have a model that keeps track of sessions for each player class PlayerSession(models.Model): player = models.ForeignKey(Player, on_delete=CASCADE) session = models.ForeignKey(Session, on_delete=CASCADE) Where the player model is class Player(models.Model): name = models.CharField(max_length=1024) email = models.EmailField(max_length=1024) and Session model is from from django.contrib.sessions.models import Session How can I create a serializer for PlayerSession?

How to inherit from another view in Django
I am trying to make a simple website where user can order someting to eat. So I've got a view with lots of methods - 'pizza_sizes' is only one of them: class PizzaOrderView(TemplateView): template_name = 'pizza/pizza_order.html' pizza_type = ProductType.objects.filter(name='Regular Pizza').values_list('id', flat=True)[0] def post(self, request): to_return = add_to_cart(request) return to_return def pizza_sizes(self): sizes = Product.objects.filter(type=self.pizza_type).values_list('size__name', flat=True).distinct() return sizes I also have a ListView displaying all products that user has in cart. class CartView(ListView): template_name = 'orders/cart.html' From this page user can either delete or update product. So I am using UpdateView to let him update it, but then again I need all those methods (that I use in PizzaOrderView). I could rewrite those methods to this view, but it doesn't make much sens, I tried to inherit it like this: class ProductUpdateView(UpdateView, PizzaOrderView): model = CartItem fields = '__all__' pizza_type = list(ProductType.objects.filter(name__contains='Pizza').values_list('id', flat=True)) def post(self, request, **kwargs): cart_id = self.kwargs.get('pk') to_return = update_user_cart(request, cart_id) return to_return def get_template_names(self): product_type = CartItem.objects.filter(id=self.kwargs.get('pk')).values_list('product__type', flat=True)[0] if product_type in self.pizza_type: self.template_name_suffix = '_pizza_update' else: self.template_name_suffix = '_form' return super().get_template_names() And then use it in my template, but then it throws an AttributeError: 'ProductUpdateView' object has no attribute 'object' As if it somehow lost its 'object' … -
Database configuration in Django
How do I use a database connection URL in setting up database config in Django as opposed to using a dictionary?

How to create an input field to change the parameters of the yelp fusion api?
I cannot create a POST request without interrupting how my entire page is rendered when I want to change my parameters.

Python / Django - Mypy: expression has type "Type[ModelInstance]", variable has type "ModelInstance"
I'm working on a Django app that provides a GraphQL api for the frontend. I'm using mypy for typechecking and when running mypy I'm encountering errors that I do not understand When running I get the following errors: api/schema.py:50: error: Incompatible types in assignment (expression has type "Type[Academy]", variable has type "Academy") api/schema.py:57: error: Incompatible types in assignment (expression has type "Type[School]", variable has type "School") api/schema.py:64: error: Incompatible types in assignment (expression has type "Type[AcademyGroup]", variable has type "AcademyGroup") This is the code that mypy is checking class AcademyType(DjangoObjectType): class Meta: model: Academy = Academy filter_fields: List[str] = ['name', 'domain', 'slug'] interfaces: Tuple = (relay.Node,) class SchoolType(DjangoObjectType): class Meta: model: School = School filter_fields: List[str] = ['name', 'academy'] interfaces: Tuple = (relay.Node,) class AcademyGroupType(DjangoObjectType): class Meta: model: AcademyGroup = AcademyGroup filter_fields: List[str] = ['name', 'academy'] interfaces: Tuple = (relay.Node,) So the lines that keep failing are variants on model: AcademyGroup = AcademyGroup, but that is just a 'Django model as type' definition that is happening all over my code (and does not seem to be generating errors) As such I'm not really sure what I am doing wrong here, so any help would be greatly appreciated. -

django: Ajax POST response not loading in template
In my django template, An AJAX call is being made for a POST Request (to create an object instance).

Using different content object passed from Views to Template depending on what button user presses
I currently have one model called Comments. After entering in a youtube Channel in a form, the user is taken to the index template that shows all the comments on that youtube channels videos that includes one of three key words (Keyword A, Keyword b , Keyword C). I would like to add a feature so there are three links/buttons on the top of the page (each for one of the keywords). The user can press that link and (without page reload (does this mean I will for sure need ajax?))just see the comments with that keyword instead of all comments with any of the three keywords. I am currently sending four content variable objects from views to the template (one with all the comments, and three other objects each that just contain the comment objects for that keyword). So the template has access to the data I need, I just need to make it so that when one of the links/buttons are clicked it only shows that content. Views def addTodo(request): new_item =Channel(channel=request.POST['channel']) #if channel exists render page with comments if Channel.objects.filter(channel=new_item.channel).exists(): channel_obj=Channel.objects.get(channel=request.POST['channel']) comments_object=Comments.objects.filter(channel=channel_obj) comments_objectA=Comments.objects.filter(channel=channel_obj, key="keywordA") comments_objectB=Comments.objects.filter(channel=channel_obj, key="keywordB") comments_objectC=Comments.objects.filter(channel=channel_obj, key="keywordC") return render(request, 'todo/index.html', {'comments_all': comments_object, 'commentsa': comments_objectA,'commentsb': comments_objectB,'commentsc': comments_objectC}) … -

Does Django create useless migrations?
When I change the verbose_name attribute of a Django Model, Django will generate a related migration (running make migrations command). However, without applying the migration (migrate command), the change seems to be applied all over the Django project. I think this is because verbose_name is something used at Django level rather than at database level. This makes me wonder: what is the purpose of this migration file? -
