How to get two distinct objects from the same view function in django according to the requirements?
I have 3 models in Django which are like: class Category(models.Model): name = models.CharField(max_length=100, unique=True) slug = models.SlugField(max_length=100, unique=True) class Subcategory(models.Model): name = models.CharField(max_length=100) slug = models.SlugField(max_length=100, unique=True) class Product(models.Model): name = models.CharField(max_length=200, unique=True) category = models.ForeignKey(Subcategory, on_delete=models.CASCADE, related_name='products') slug = models.SlugField(max_length=150, unique=True) The view function which I want to modify currently looks like this: def product_list(request, category_name): subcategory = get_object_or_404(Subcategory, slug=category_name) subcategory_name = subcategory.name product_list = subcategory.products.all() context = { 'name':subcategory_name, 'product_list':product_list, } return render(request, 'products/product_list.html', context) In one of my html templates each category is displayed along with the subcategories under it. If anyone clicks on the category name instead of the subcategory under that category name, I want the views function to display all the products which come under that category and not just one subcategory under that given category. I can create a separate view to do that but I want to know if there's a way to do that in the same view function. -

No ID assigned to objects when created in Django
I have a Class in my models.py named Order class Order(models.Model): customer_name = models.ForeignKey( settings.AUTH_USER_MODEL, on_delete=models.CASCADE, related_name='customer_name', ) order_individual_price = models.IntegerField(default=1) order_name = models.CharField(max_length=200) order_quantity = models.IntegerField(default=1) order_total_price = models.IntegerField(default=1) def __str__(self): return self.order_name In my views.py I create a new instance of order when a button is pressed def ordering(request): latest_order = Order.objects.all() menu = Menu.objects.all() if request.method == 'POST': if request.user.is_authenticated: menu_instance = request.POST.get('add') if menu_instance: get_order = Menu.objects.get(id=menu_instance) get_price = get_order.Menu_price new_order = Order.objects.create(customer_name=request.user, order_name=get_order, order_individual_price=get_price) return redirect('shop-ordering') order_instance = request.POST.get('delete') else: messages.info(request, f'Please Sign In First') return redirect('login') return render(request, 'shop/ordering.html', {'title':'Ordering', 'latest_order': latest_order, 'menu':menu}) However, when I try to get the ID of the object it throws this error Traceback (most recent call last): File "<console>", line 1, in <module> File "/Users/alan/Desktop/FRIENDS_CAFE_DJANGO/venv/lib/python3.8/site-packages/django/db/models/manager.py", line 82, in manager_method return getattr(self.get_queryset(), name)(*args, **kwargs) File "/Users/alan/Desktop/FRIENDS_CAFE_DJANGO/venv/lib/python3.8/site-packages/django/db/models/query.py", line 415, in get raise self.model.DoesNotExist( shop.models.Order.DoesNotExist: Order matching query does not exist.

Django query based on another query results
I have 4 models in my simplified design class modelA(models.Model): name = models.CharField() class modelsUser(model.Model): username = models.CharField() class bridge(models.Model): user = models.ForeignKey(modelUser, on_delete=models.CASCADE, related_name='bridges') modelA = models.ForeignKey(modelA, on_delete=models.CASCADE, related_name='bridges') class subModelA(models.Model): modelA = models.ForeignKey(modelA, on_delete=models.CASCADE, related_name='subModelAs') value = models.IntegerField() class subModelB(models.Model): modelA = models.ForeignKey(modelA, on_delete=models.CASCADE, related_name='subModelBs') text = models.TextField() What I am trying to to is to get all subModelBs and subModelAs that are for modelAs for which given modelUser have bridge. I've started with this: user = modelUser.objects.get(pk=1) bridges = user.bridges.all() What I've been thinking is something like this: subModelBs = modelB.objects.filter(modelA__in=bridges__modelA) but unfortunately it doesn't work because of error that __modelA is not defined. Is there any proper way to do this? -
How exactly does CASCADE work with ManyToMany Fields in Django
Im Wondering how exactly does CASCADE work with ManyToMany Fields in Django. A short example: class Project(Model): name = TextField(null=False) class Job(Model): projects = ManyToManyField(Project, on_delete=CASCADE, null=False) name = TextField(null=False) As you can see I have a ManyToManyField here. So basically a Project can have mutiple Jobs and a Job can belong to Multiple different Projects. What I want is that a Job is automatically deleted only when all Projects it belongs to are deleted. Does CASCADE work like that in this scenario? -

Visualize link has been clicked or not
I'm currently working on a web app in which I would like to display to the user whether they have visited the link already or not. The code that displays the links is fairly simple, as seen below. <ul> <li><a href="http://google.com">google</a></li> <li><a href="http://facebook.com">facebook</a></li> <li><a href="http://amazon.com">amazon</a></li> </ul> What I would like is to visualize that a link has been clicked by just adding a checkmark, or something along those lines, to the right of the link. How would I go about doing that? I'm working with Django for this project so a Django-specific solution would be great. -
npx create-react-app command does not work, returns ES module error instead
Here is the command that I ran to try to create a React app and the resulting error log. I have been able to successfully run it three times before with the command $ npx create-react-app, but now every time that I run it, it does not work and instead returns an error related to ES modules. I have been experimenting with many ways to integrate React with Django, but I don't think that I edited any core files in doing so that would have caused this error. I am completely new to React and Node.js so any advice would be greatly appreciated. npx: installed 99 in 7.591s Must use import to load ES Module: /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/index.js require() of ES modules is not supported. require() of /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/index.js from /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/run-async/index.js is an ES module file as it is a .js file whose nearest parent package.json contains "type": "module" which defines all .js files in that package scope as ES modules. Instead rename /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/index.js to end in .cjs, change the requiring code to use import(), or remove "type": "module" from /Users/(username)/.npm/_npx/27993/lib/node_modules/create-react-app/node_modules/is-promise/package.json.``` -

Efficient way of avoiding adding duplicate entries to Django model
I've read quite a few posts on how to make a Database/Model unique in Django and it all seems to work. However, I do not see any posts discussing an efficient way of avoiding adding duplicate entries to a database. My model looks like this: # from app.models class TestModel(models.Model): text = models.TextField(unique=True, null=True) fixed_field = models.TextField() The way I currently avoid adding duplicate entries without getting an error is as follows. # from app.views posts = ["one", "two", "three"] fixed_field = "test" for post in posts: try: TestModel(text=post, fixed_field = fixed_field).save() except IntegrityError: pass If I would not do this I would get an IntegrityError. Is there any way I could make this more efficient? -

Filtering in Django ModelViewSet
I don't think I'm doing this correctly. What I'm trying to do is prevent data from being returned if it doesn't match my criteria. Here are the criteria: User should be able to see the project if: If the object is private and they are the owner -- OR -- The project is not private If the user is the owner, or they are a member of the assigned group As far as I can tell, it's not getting the data into the is_private and owner variables I set. Every tutorial I read online though seems to do it in this way. So I'm pretty lost right now. class ProjectListViewSet(viewsets.ModelViewSet): queryset = Project.objects.all().order_by('name') serializer_class = ProjectLightSerializer authentication_classes = [TokenAuthentication, ] permission_classes = [IsAuthenticated, ] def get_queryset(self): queryset = super().get_queryset() is_private = self.request.data.get('is_private') owner = self.request.data.get('owner') print(is_private) print(owner) if is_private: if owner == self.request.user.id: queryset = queryset.filter(owner__exact=self.request.user) else: if owner == self.request.user.id: queryset = queryset.filter(owner__exact=self.request.user) else: queryset = queryset.filter(groups__in=self.request.user.groups.all()) return queryset Any assistance would be greatly appreciated.

How to work with external API from Django admin
I have a problem to solve with Django. I need in some way from the admin area to be able to use an external API to do some HTTP requests, GET and POST. I'm not sure how a good approach would be to solve this. I have only handled this on the frontend before. I should be able to get a list of orders from the API, update an order, get a specific order with details, post a new order etc. I'm thinking such as when you register a model and then registering it with ModelAdmin, would that be possible to use the API to load it in similar way there and handle the API? Should I store the API data in a model to a database? Should I create create a custom made Django admin page? Other ideas? -

Djoser return access and refresh token when registering user
I am trying to get access and refresh tokens when the user registers using the /auth/users/ endpoint. I have already extended the serializer and it is showing all custom fields. It registers the user successfully and returns the result as follows: { "mobile": "12345", "driving_id": "478161839", "full_name": "John Doe", } This is where I would want to have an access and refresh token. I read that djoser uses django simple jwt library to provide access and refresh tokens. This is the function to create the tokens manually which I am able to do but the only thing I am not understanding is where to return the data with other details. from rest_framework_simplejwt.tokens import RefreshToken def get_tokens_for_user(user): refresh = RefreshToken.for_user(user) return { 'refresh': str(refresh), 'access': str(refresh.access_token), } -
