Django rest Framework Endpoint - django

Question

I need to get this endpoint /comments/int:post_id/
I can GET and POST comments and posts but I need to show all comments to specific post. I don´t know how to connect it. My code look like
comment urls
urlpatterns = [
path('', views.CommentsView.as_view()),
path('<int:post_id>/', views.CreateCommentsView.as_view()),
]
comment view.py
# I get all comments/
class CommentsView(ListCreateAPIView):
queryset = Comment.objects.all()
serializer_class = CommentSerializer
# Comments to specific post
class CreateCommentsView(ListCreateAPIView):
queryset = Comment.objects.all()
serializer_class = CommentSerializer
lookup_url_kwarg = 'post_id'
def perform_create(self,serializer):
post = self.kwargs.get('post_id')
post =set.get_queryset().filter(id = 'post_id')
post.comments.add(comment)
post = Post.objects.filter(id=self.kwargs.get('post_id'))
serializer.save(user=self.request.user, post=post)
comment serializer
from rest_framework import serializers
from .models import Comment
from django.contrib.auth import get_user_model
User = get_user_model()
class CommentSerializer(serializers.ModelSerializer):
class Meta:
model = Comment
fields = ['id', 'user', 'post', 'content', 'created']
class UserSimpleSerializer(serializers.ModelSerializer):
class Meta:
model = User
fields = ['username']
class CommentSimpleSerializer(serializers.ModelSerializer):
user = UserSimpleSerializer()
class Meta:
model = Comment
fields = ['user', 'content', 'created']
post.view.py
class PostList(generics.ListCreateAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
class PostDetail(generics.RetrieveUpdateDestroyAPIView):
queryset = Post.objects.all()
serializer_class = PostSerializer
class LikePost(generics.UpdateAPIView):
permission_classes = [IsNotPostUser]
queryset = Post.objects.all()
serializer_class = PostSerializer

Answer 1

you can pass the post_id in url parameters for /comments/ endpoint and call HTTP GET method. Then in CommentsView you need to override the get_queryset method. Your implementation will be like
class CommentsView(ListCreateAPIView):
serializer_class = CommentSerializer
def get_queryset(self):
query = self.request.query_params.get('post_id', None)
if query is not None:
queryset = Comment.objects.filter(post_id=post_id)
else:
queryset = Comment.objects.all()
return queryset
This /comments/ endpoint will return all the comments and this one /comments/?post_id=1 will return comments only related to specified post.
