I am a beginner in Django. Right now, I am doing a simple app, called GameReview. It will allow the users to add the reviews of their favorite games. Right now, I am facing a 404 error.

Best practice to insure the connection and response from external API results
I have this code in python (using django firmware) that connects to an external API and update some values in that service. Each step depends on the previous step (for step 2 to work step 1 must return True and so forth that include a valid connection to the API). How can I insure that all of these steps takes place at the same time and if a single step fails how can I rollback and run all them at once in another try. here is the code. note that each class method do something in that external service. # 1. add new value to account if cls.add_balance(subscription_code, increase_amount): # 2. set new base balance if cls.set_topup_reset_action( subscription_code, new_base_balance, ): # 3. renew filters new_base_balance_20_percent = math.floor((Decimal( new_base_balance) * Decimal(20)) / Decimal(100)) if cls.set_filter_80_percent( subscription_code, new_base_balance_20_percent, ) and cls.set_filter_100_percent( subscription_code, ): # 4. renew thresholds if cls.set_threshold_profile_80_percent( subscription_code, ) and cls.set_threshold_profile_100_percent( subscription_code, ): return True return False -
creating custom or modified url using router for retrive method of ModelViewSet
I want to create a custom or modified url using router for ModelViewSet. Current scenario: /models.py class BlogPost(models.Model): title = models.CharField(max_length=300) description = models.TextField() slug = models.SlugField(max_length=300, unique=True) /serializers.py class BlogListSerializer(serializers.ModelSerializer): class Meta: model = BlogPost exclude = ('id',) /views.py class BlogViewSet(ModelViewSet): queryset = BlogPost.objects.all() serializer_class = BlogListSerializer /urls.py router = DefaultRouter() router.register(r'blog', BlogViewSet, basename='blog') urlpatterns = router.urls Now, I can access the url as below: list https://localhost:8000/blog retrieve https://localhost:8000/blog/1 As You can see that the retrieve url can be called using the pk or id. But I have created a model field called slug and its unique. My question is that how do I modify the retrieve url so that I can call the retrieve url using the slug field. For example: https://localhost:8000/blog/test-slug Note: Why do I want to create a url using slug? Answer: I want to use the urls for sitemap. -

Django: What is the escape() function used for?
I am trying to make a calendar in Django, and in one of the tutorials I am reading there is the following line of code: from django.utils.html import conditional_escape as esc In the Django documentation it says that conditional_escape() is ' Similar to escape(), except that it doesn't operate on pre-escaped strings'. The documentation for escape() says: 'Returns the given text with ampersands, quotes and angle brackets encoded for use in HTML'. I have found an example usage of escape(): from django.utils.html import escape escape("<strong style='font-size: 12px'>escaped html</strong>") Output: '&lt;strong style=&#39;font-size: 12px&#39;&gt;escaped html&lt;/strong&gt;' What is the purpose of the escape() function? I have searched online but all the sites just talk about what it does. I am not sure why one would want to use this function. Any insights are appreciated. -

Django Prevent Customers From Buying A Different Paid Membership If They Currently Have One
I am having trouble figuring out the logic of my code to be able to prevent customers from buying another membership if they currently have one already (see image links below). For example, if they are paying for a Professional Membership, I do not want them to be able to click the Select button for Enterprise. If they are an Enterprise paying customer, I do not want them to be able to pay for a Professional Membership.

Django: apply validator at model level instead of column level
Let's say I have the following Django model: class PersonClub(models.Model): person = models.ForeignKey(Person, on_delete=models.CASCADE) club = models.ForeignKey(Club, on_delete=models.CASCADE) year = models.PositiveSmallIntegerField() class Meta: unique_together = ("person", "club", "year") I need to apply a validator at the model level that enforces this rule: A person can belong to only 3 different clubs in a given year.

Serialize ManyToManyFields with different serializers in ViewSets
I have a model with ManyToMany relations which I call containers. In my API I want to get the entry that match a certain ID in this container. For example, I want to have the container with the ID "2" in the beer_container. But of course only the container which is available in the TotalOrder. My model looks like this: class TotalOrder(models.Model): beer_container = models.ManyToManyField(BeerContainer, blank=True) foreign_beer_container = models.ManyToManyField(ForeignBeerContainer, blank=True) ..... My serializer: class TotalOrderSerializer(serializers.ModelSerializer): beer_container = BeerContainerSerializer(many=True) soft_drink_container = SoftDrinkContainerSerializer(many=True) .... class Meta: model = TotalOrder fields = '__all__' In the views.py I have my TotalOrderListCreate class, which returns the whole total order with its containers. And this works very well. class TotalOrderList(generics.ListAPIView): serializer_class = TotalOrderSerializer def get_queryset(self): table_number = 'table_number' try: table = Table.objects.filter(number=self.kwargs.get(table_number)) queryset = TotalOrder.objects.filter(table__in=table) except (Table.DoesNotExist, TotalOrder.DoesNotExist): return [] return queryset But now, I want to get one container with its ID from that TotalOrder. For example: api/total-order/1/beer_container/2. I have tried this way, but I don't know how to return my queryset into the TotalOrderSerializer because now I have for example the data of an BeerContainerSerializer. I've tried this, but without any luck. class TotalOrderDetail(generics.ListAPIView): serializer_class = TotalOrderSerializer def get_queryset(self): table_number = self.kwargs.get('table_number') order_id = … -

For now on I have in my template a paragraph like this <p class="...">{{ post.content }}</p> and if this Post's content contains a link or #hashtag it is rendered as a normal text with the rest of the post. How can I customize it? For example change text-color and add tag around it? -
Django - Annotate with count across ManytoMany relationships (refrase)
Django - Annotate with count across ManytoMany relationships I am not able to find the way to annotate a queryset with a count of how many times an element is used in a many-to-many relationship. class Profile(models.Model): [...] # Profile can have multiple roles roles = models.ManyToManyField('Role', blank=True) [...] class Role(models.Model): company = models.ForeignKey(Company, on_delete=models.CASCADE) name = models.CharField(blank=True, max_length=30) description = models.CharField(blank=True, max_length=300) [...] For example I would have 5 roles: Role1 Role2 Role3 Role4 Role5 And 2 profiles with following roles assigned: Profile1 Role 1 Role 2 Profile2 Role 1 Role 3 Role 4 I need to have the oposite than @ha-duy: Profile: name, role_count=2 Profile: name, role_count=3 Any ideas? Thanks! -
Django request.body always printing nonsense result (b'')
I am new to django , I started working on an existing Vuejs/Django project to easily understand how things are working . I wrote a new specific view in views.js def hello(request): print(req.body) return HttpResponse('hello') Then in urls.py I added the following: path('hello/',views.hello,name='hello') At first I tried sending a plain/text , but the print function shows the following b'' I tried printing request.data but it says WSGIRequest' object has no attribute 'data' I tried sending a JSON and using the following : body_string = request.body.decode("utf-8", "ignore") data = json.loads(body_string) Result : Expecting value: line 1 column 1 (char 0)Expecting value: or: data = json.loads(request.data.get('_content')) Result: 'WSGIRequest' object has no attribute 'data' none of that seems to be working . The app I am working on seems to be working fine but it has no specific URL that's way I am stuck as I have no example , even here I couldn't find anything that helps. -
Django DRF: How to make a todo item dependent to another item
Hi I am building an todo app according to a tutorial and I want to improve it a bit. I want a todo item dependent to another. For example if todo1 has dependency to todo2, it shouldn't allow me to check todo1 before complete todo2. Here is my models.py from django.db import models from datetime import datetime from django.contrib.auth.models import User class TodoList(models.Model): name = models.CharField(max_length=200, default="blank title") is_completed = models.BooleanField(default=False) completed_at = models.DateTimeField(default=datetime.now(), null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) owner = models.ForeignKey(User, on_delete=models.CASCADE, null=True) class Meta: verbose_name = "Todo List" verbose_name_plural = "Todo Lists" ordering = ["name","created_at", "is_completed", ] def __str__(self): return self.name class TodoItem(models.Model): name = models.CharField(max_length=200, default="blank title") todo_list = models.ForeignKey(TodoList, on_delete=models.CASCADE, null=False) description = models.TextField(max_length=200, default="Blank text") is_completed = models.BooleanField(default=False) completed_at = models.DateTimeField(default=datetime.now(), null=True, blank=True) created_at = models.DateTimeField(auto_now_add=True) deadline = models.DateTimeField(default=datetime.now(), null=True, blank=True) owner = models.ForeignKey(User, on_delete=models.CASCADE, null=True) previous_item = models.IntegerField(default=0) class Meta: verbose_name = "Todo Item" verbose_name_plural = "Todo Item" ordering = ["id","created_at", "is_completed","deadline","name" ] def __str__(self): return self.name Views.py from django.shortcuts import render from rest_framework.views import APIView from django.http import HttpResponseRedirect from django.contrib.auth.models import User from django.contrib.auth.forms import UserCreationForm from rest_framework import viewsets, permissions, status from rest_framework.decorators import action, api_view from rest_framework.response import Response from …
