from rest_framework import serializers
from django.db import models
class Bar(models.Model):
id = models.IntegerField()
class Meta:
app_label = 'test'
class Foo(models.Model):
bar = models.ForeignKey( Bar, on_delete=models.PROTECT, )
class Meta:
app_label = 'test'
class FooSerializer(serializers.ModelSerializer):
class Meta:
model = Foo
fields = ( 'bar', )
extra_kwargs = { 'bar': { 'source': 'bar.id' } }
I copied this from DRF_Github_issues
<https://github.com/encode/django-rest-framework/issues/7368> .
the source in the extra_kwargs doesn't work more than one depth relation
(bar.id) , but works with one (bar) .
if I defined the field in the serializer class , I'll have to redefine the
validators of the model as well , what's the best workaround without
redefining the validators .
