You can use the class FooSerializer(serializers.ModelSerializer):
class Meta:
model = Foo
fields = ['id', 'some_field', 'bar_field']
extra_kwargs = {'bar_field': {'source': 'bar.bar_field'}} |

I just realized that when using a
ModelSerializerand adding additional fields from related models directly as fields by specifying thesourceargument on a field, the field does not inherit the field properties as regular fields for models do.For example
The serializer field for
some_fieldhasmax_length=100whereasbar_fielddoes not "inherit" the properties fromBar.bar_field.I understand that the intended way is to use a nested serializer. I am wondering though if there is a way to achieve this with fields specifying the
sourceargument.Beta Was this translation helpful? Give feedback.
