Async view with serializer Django 3.1
I'm trying to create an async view to solve an endpoint with Django 3.1. I have my AsyncView and within this view I have the next code lines : try: db_result= await sync_to_async(list)(Plan.objects.filter()) serializer = MySerializer(db_results, many=True) return serializer.data except Exception: # Handle Exception Code Within my serializer I have a custom field. Its data is retrieved doing other queries to the Database using its obj property. This is where I am having some problems since this is an async context. Serializer Code: MySerializer(serializers.ModelSerializer): custom_field = serializers.SerializerMethodField(required=False) def get_custom_field(self, obj): try: # This is failing, is not retrieving data from DB since it's async context related_stuff = obj.related_stuff.filter(filter_condition=filter_condition) # More code after this . . . . return custom_field_object except Exception: return None I've tried to put an await before the Serializer in my View Code and add async property to get_custom_field method (with the sync_to_async operator in the db query). Got nothing. Anyone know how to solve this specific problem? -

Video converter with python Issue
I am creating video converter using django. I came across this module (https://travis-ci.org/senko/python-video-converter.png?branch=master)](https://travis-ci.org/senko/python-video-converter) and I have used it in my program. My problem is i want the script to run forever and I also have a function that checks for new videos added so that the conversion can be done automatically. The code is not working as i expected.
