How to filter extra context data from one serializer when used in another?
With django rest framework, I have two serializers for two different models. Lets say, the models are Author and Book. Author Model has the fields: name, address, phone, email, description and created_at while the book has the fields: name, publisher_name, genre, description, created_at and author(foreign key to Author model). Now, I have the serializers defined for Author and Book: class BookSerializer(serializers.Serializer): class Meta: model = Book exclude = ['created_at'] class AuthorSerializer(serializers.Serializer): books = BookSerializer(many=True,required=False,null=True) class Meta: model = Author exclude = ['created_at'] The current schema gives the return of Book serializer for instance as: { "id":1, "name":"Book_name", "publisher_name":"Publisher", "genre":"g", "description":"Book description", "author":1 } While the return of authorserializer is: { "id":1, "address":"Address", "phone":9812312312, "email":"email@email.c", "description":"this is description", "books": [ { "id":1, "name":"Book_name", "publisher_name":"Publisher", "genre":"g", "description":"Book description", "author":1 } ] } The thing is that I dont want all the details in the books of the return for Authorserializer, and want to exclude the description and genre. How to do this? -
Django append function result to object item
I am using django-haystack and I am trying to implement a way to append the page number to a pdf link in order to open it in the specific page. My goal is to open the pdf in the page where the first hit is found. I know the position of the hit in my document and the position where the page changes. For example i know that the first hit starts at character 2067 and the second page changes at character 3000, so i have to open the pdf at the second page. My question is: how can i get the result of the function that finds the number of the page where the pdf should open and render it ? I am thinking that the result should be something like that <a href="{% static 'img/sample.pdf#page={{ pageNumber }}' %}"> but i am open to any other suggestions. P.S. I am not asking you to solve my problem. I am asking for suggestions or a constructive discussion as i am new to django. Thank you in advance -

Expire the user activation link and remove from database in django
I have an user signup, where the user's account is activated after link with a token send to their email address is clicked. I want to expire the link and delete their data from the database if the specific link is not clicked within 24 hours. I have read it in one place, that the link is expired after 48 hours, is that correct? Here is my question - How can I automatically remove those users who do not click on the activation link with in 24 hours? (So far I can do that by going to admin panel and by checking email is confirmed or not) Here is my activate function, def activate(request, uidb64, token): try: uid = force_text(urlsafe_base64_decode(uidb64)) user = User.objects.get(pk=uid) except (TypeError, ValueError, OverflowError, ObjectDoesNotExist): user = None if user is not None and account_activation_token.check_token(user, token): user.is_active = True user.email_confirmed = True user.save() login(request, user) return redirect('home') else: return render(request, 'user/account_activation_invalid.html') This is my tokens.py to create token, from django.contrib.auth.tokens import PasswordResetTokenGenerator from django.utils import six class AccountActivationTokenGenerator(PasswordResetTokenGenerator): def _make_hash_value(self, user, timestamp): return ( six.text_type(user.pk) + six.text_type(timestamp) + six.text_type(user.email_confirmed) ) account_activation_token = AccountActivationTokenGenerator() What should I change to achieve that? -
Create modal dynamically from json response
I am dumping a html code of a div in json format at client side.I am using Django Channels Groups to do this.

I know I can use Apache virtualhosts but it's such a hassle and I wonder if there's a better approach. -

When a user creates a post using the CreateView I want it so when a user submits the Post, they then see the post they just made. But for some reason my get_absolute_url() is not working. Prior to this I started to work on slugifying the Post and Category models and haven't been able to see if they work due to the fact get_absolute_url won't work.

Set nginx proxy for react multi-stage build with docker compose
I am - once again - very confused, with nginx, docker and react. Here is what is what I want: 1.) a Django REST api that exposes a port only locally 2.) I want the staticfiles of the REST api handled by nginx 3.) a ReactJS front end that is served via nginx on port 80 (I dont know if it is nessesary to serve react via nginx - but I've heard it reduces image size). The problem: It does not work. All containers can run individually but serving React via nginx as well as the restAPI goes over my head. What I saw is that the image I am layering in reactJS "tiangolo/node-frontend:10" also copies a nginx.conf file that may overwrite mine? Can somebody tell me wether or not I am completely on the wrong path here? Using a million tutorials, I am here: nginx.conf upstream website_rest { server restapi:8000; } upstream website_frontend { server frontend:8080; } server { listen 80; location /rest_call/ { proxy_pass http://website_rest; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location / { proxy_pass http://frontend; proxy_set_header X-Forwarded-For $proxy_add_x_forwarded_for; proxy_set_header Host $host; proxy_redirect off; } location /rest_call/staticfiles/ { alias /usr/src/website-dj/staticfiles/; } } This is the … -

How to handle foreign keys with Django Rest Framework
I'm struggling to make my API work, the tutorials are quite tricky about this part. I want to have a '/comments/' POST request with body {movie_id: 1, content="Some comment") and connect it to some Movie. In serializer I'm getting: {'movie': [ErrorDetail(string='This field is required.', code='required')]} How can I map movie_id to movie? By the way, I can change the name to movie if this would be easier. Models.py: from django.db import models from django.utils import timezone class Movie(models.Model): title = models.CharField(max_length=200) year = models.IntegerField() class Comment(models.Model): content = models.TextField(max_length=300) publish_date = models.DateField(default=timezone.now()) movie = models.ForeignKey(Movie, on_delete=models.CASCADE, related_name='movie_id') serializers.py: class MovieSerializer(serializers.HyperlinkedModelSerializer): class Meta: model = Movie fields = '__all__' class CommentSerializer(serializers.HyperlinkedModelSerializer): movie_id = serializers.PrimaryKeyRelatedField(many=False, read_only=True) class Meta: model = Comment fields = '__all__' views.py (for Comment, Movie works fine): from .models import Movie, Comment from rest_framework import viewsets, status from rest_framework.response import Response from .serializers import MovieSerializer, CommentSerializer class CommentViewSet(viewsets.ModelViewSet): queryset = Comment.objects.all() serializer_class = CommentSerializer def create(self, request, *args, **kwargs): serializer = CommentSerializer(data=request.data, context={'request': request}) if serializer.is_valid(raise_exception=True): serializer.save() return Response(serializer.data, status=status.HTTP_201_CREATED) else: return Response(serializer.errors, status=status.HTTP_400_BAD_REQUEST)
