Description
I need to be able to add links to read-only resources into the relationships-object of a resource as easily as adding a non-link field with SerializerMethodField. (Generating the link with SerializerMethodField is trivially easy, but they are links.) In all cases so far I can generate the link from data in the object.
Is this supposed to be possible at all or is it just poorly documented?
I've tried non-model serializers, ResourceRelatedField, HyperlinkedRelatedField, and I'm now at the stage where the code is running under pdb in an attempt to figure out how things are supposed to work. It seems such a straightforward, obvious thing to do.
I'm talking about things like this:
class Some(Model):
data = models.CharField()
class SomeSerializer(serializers.ModelSerializer):
extra = serializers.SomethingMagicField()
class Meta:
model = Some
fields = ['data','extra']
def extra(self, obj):
return 'other_url/{}/'.format(obj.pk)
leading to
{
"data": {
"type": "Some",
"id": "1",
"attributes": {
"data": "foo",
},
"relationships": {
"extra": {
"links": {
"related": "other_url/1/"
}
}
}
}
}
instead of
{
"data": {
"type": "Some",
"id": "1",
"attributes": {
"data": "foo",
"extra": "other_url/1/"
}
}
}
