model field named url and django rest framework url

model field named url and django rest framework url

I started to use the great django-rest-framework days ago. I'm not able to
solve this simple issue.
My model contains a models.URLField named url.
My serializers.py file:
class ModelSerializer(serializers.HyperlinkedModelSerializer):
owner = serializers.Field(source='owner.username')
class Meta:
model = Model
fields = ('url', 'owner', 'title', 'abstract', 'category',
'position', 'param1')
Checking the API result the field 'url' is populated with model.URLField.
"results": [
{
"url": "http://www.web.com",
"owner": "me",
"title": "title of the stuff"
}
Instead I would like to have
"results": [
{
"url": "http://localhost:8000/en/apiv1/maps/4/",
"url_in_model": "http://www.web.com",
"owner": "me",
"title": "Forest fire"
}
How can I solve? Thanks
