Question

How do I serialize a many-to-many field into list of something, and return them through rest framework? In my example below, I try to return the post together with a list of

Answer 1

In the serializer on init method you can pass the queryset to the field and rest_framework valide the ids on that queryset

1) first extend your serializer from serializers.ModelSerializer

class YourSerializer(serializers.ModelSerializer):

2) include the field on the meta class

class YourSerializer(serializers.ModelSerializer):
  class Meta:
        fields = (..., 'your_field',)

3) in the init method:

def __init__(self, *args, **kwargs):
    super(YourSerializer, self).__init__(*args, **kwargs)
    self.fields['your_field].queryset = 

You can limit the queryset for that field under any argument using filter or exclude like normally you do. In case that you want include all just use .objects.all()
