python - Django REST Framework nested serializer having no effect -

i attempting set nested serializer in django rest framework, after following short guide in documentation, http://www.django-rest-framework.org/api-guide/relations/#nested-relationships, have had no change in serialized data.

models.py

class franchise(models.model):     id = models.autofield(primary_key=true)     name = models.charfield(max_length=255)   class item(models.model):     id = models.autofield(primary_key=true)     franchise = models.foreignkey(franchise, on_delete=none)     title = models.charfield(max_length=255) 

initial serializers.py

class itemlistserializer(serializers.modelserializer):     class meta:         model = item         fields = ('id', 'franchise', 'title')   class franshisedetailserializer(serializers.modelserializer):     class meta:         model = franchise         fields = ('id', 'name', 'items') 

when query itemlistserializer query set expected:

[     {         "id": 1,         "franchise": 1,         "title": "item 1",     },     {         "id": 2,         "franchise": 1,         "title": "item 2"     },     {         "id": 3,         "franchise": 2,         "title": "item 3",     } ] 

and expected result when query franchisedetailserializer pre-existing franchise object.

{     "id": 1,     "name": "franchise 1" } 

now, when change franchisedetailserializer, per drf guide on nested relations:

class franshisedetailserializer(serializers.modelserializer):     items = itemlistserializer(many=true, read_only=true)      class meta:         model = franchise         fields = ('id', 'name', 'items') 

i expect following result:

{     "id": 1,     "name": "franchise 1"     "items": [        {"id": 1, "title": "item 1", "franchise": 1},        {"id": 2, "title": "item 2", "franchise": 1}     ] } 

but instead, no change, though hadn't updated franchisedetailserializer @ all:

{     "id": 1,     "name": "franchise 1" } 

the worst part me not getting kind of error, i'm not seeing results.

any , appreciated, thanks.

actually missed tiny part of docs :)

album = models.foreignkey(album, related_name='tracks')

define related_name in foreignkey

franchise = models.foreignkey(franchise, on_delete=none, related_name='items') 

after stuff started working me.
