Django rest framework non_atomic_requests based on HTTP method
I am using Django Rest Framework and its class-based view, with database connection set to ATOMIC_REQUESTS=True. To optimize the application, I would like to have it so that only PUT and POST requests are under transaction, but not GET. Since I have ATOMIC_REQUESTS on, the documentation says to use the decorator on the dispatch() method in the view. So this is what I tried: class MyView(APIView): def get(): print("I am in a transaction:", not transaction.get_autocommit()) return Response({}) def post(): print("I am in a transaction:", not transaction.get_autocommit()) return Response({}) def put(): print("I am in a transaction:", not transaction.get_autocommit()) return Response({}) def dispatch(self, request, *args, **kwargs): """Override dispatch method and selectively apply non_atomic_requests""" if request.method.lower() == "get": return self.non_atomic_dispatch(request, *args, **kwargs) else: return super().dispatch(request, *args, **kwargs) @transaction.non_atomic_requests def non_atomic_dispatch(self, request, *args, **kwargs): """Special dispatch method decorated with non_atomic_requests""" return super().dispatch(request, *args, **kwargs) This does not work, since the get method still reports itself as under transaction, however, if I switch the decorator to look like this: ... @transaction.non_atomic_requests def dispatch(self, request, *args, **kwargs): if request.method.lower() == "get": return self.non_atomic_dispatch(request, *args, **kwargs) else: return super().dispatch(request, *args, **kwargs) def non_atomic_dispatch(self, request, *args, **kwargs): return super().dispatch(request, *args, **kwargs) ...

Notion type table save to database
As some of you may be aware, notion has the ability for users to create their own table with speicific fields. With the project that I am interested in doing, I am finding it hard to find a tutorial or for somebody to have the same question as me. What I am asking is: How would I go about creating a table that the end-user can create and add different dynamic colums to a table and for that to save on the database??? I have tried using a chrome web extension to show me the technologies that notion used to maybe get some idea but to be honest, I have none. Anyone with any answer will be much appreciated.

What is the correct way to post images on django-rest-framework server using javascript?
I have a POST API view that accepts an image and a style sting and returns a styled image. It works on postman just fine but I cannot get it to work using fetch API.

display data in multiple columns with for loop
I'm sure this is a simple answer but for the life of me I cant figure / find out how to go about this. I want to display blog posts from my data base in three equal columns. When I start looking into the bootstrap docs this is the code given. <div class="container"> <div class="row"> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> <div class="col-sm"> One of three columns </div> </div> </div> However If I go to implement it I dont understand how i would be able to put the for loop on it without it repeating everything 3 times. IE: {% for post in posts.all %} <div class="row"> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> <div class="col-sm"> <img class="post-image" src="{{ post.image.url }}" /> </div> </div> {% endfor %} If you could please point me in the right direction on how to go about this it would be very much appreciated bootstrap is not a requirement. -
