python - Django rest framework: override create() in ModelSerializer passing an extra parameter -

i looking way ovverride default .create() method of modelserializer serializer in django rest framework dealing parameter.

in original django model have overridden default.save() method managing extra param. .save() can called in way: .save(extra = 'foo').

i have create modelserializer mapping on original django model:

from originalmodels.models import originalmodel rest_framework import serializers  class originalmodelserializer(serializers.modelserializer):      # model fields     class meta:         model = originalmodel 

but in way can't pass extra param model .save() method.

how can override .create() method of originalmodelserializer class take (eventually) extra param account?

hmm. might not perfect answer given don't know how want pass "extra" in (ie. field in form normally, etc)

what you'd want represent foo field on serializer. present in validated_data in create, can make create following

def create(self, validated_data):     obj = originalmodel.objects.create(**validated_data)     obj.save(foo=validated_data['foo'])     return obj 

you'd want @ default implementation of create of other things though (like remove many-to-many relationships, etc.).
