Django in one serialize pull out child objects - django

Question

This my models
class Dictionary(models.Model):
id = models.UUIDField(primary_key=True, default=uuid.uuid4, editable=False)
parentId = models.UUIDField(editable=True, null=True)
name = models.CharField(max_length=100)
date_create = models.DateTimeField(auto_now=True)
date_end = models.DateTimeField(auto_now=False, null=True)
class Teacher(models.Model):
name = models.CharField(max_length=100)
message = models.CharField(max_length=300)
status = models.OneToOneField(Dictionary, on_delete=models.CASCADE)
this is my urls
from django.urls import path
from . import views
urlpatterns = [
path('get', views.GetViewSet.as_view({'get': 'list'})),
]
This is ViewSet
class GetViewSet(viewsets.ModelViewSet):
MyApiObj = null
#property
def api_object(self):
return namedtuple("ApiObject", self.request.data.keys())(*self.request.data.values())
def get_serializer_class(self):
GeneralSerializer.Meta.model = apps.get_model(app_label=self.MyApiObj.app, model_name=self.MyApiObj.object)
return GeneralSerializer
def post(self, request):
self.MyApiObj = self.api_object
return self.select_api()
def select_api(self):
queryset = QueryHelper.select(self.MyApiObj)
serializer = self.get_serializer(queryset, many=True)
return Response(serializer.data)
Serializer
class GeneralSerializer(serializers.ModelSerializer):
class Meta:
model = None
fields = '__all__'
My post parameters to django
{
"app":"leads",
"object":"Teacher",
"settings":{
},
"data":{
}
}
answer:
[
{
"id": 1,
"name": "John",
"message": "Hi everyone",
"status": "e3b86ed4-8794-413b-994c-b1ec0a43eebe"
}
]
Problem is Dictionary(status) model give me id(uuid) but i need whole object without creating new serializer for Dictionary. i do univeral serializer for all models in my app
Try this:
class DictionarySerializer(serializers.ModelSerializer):
class Meta:
model = Dictionary
fields = '__all__'
class GeneralSerializer(serializers.ModelSerializer):
status = DictionarySerializer(required=True)
class Meta:
model = None
fields = '__all__'
But it is not good for me because 1) Without other serializer 2) I need Universal serializer for all models and with child model in all models of my project. Help me please)
I need something like this
[
{
"id": 1,
"status": {
"id": "e3b86ed4-8794-413b-994c-b1ec0a43eebe",
"parentId": "dc6cf7da-b82c-11e9-a2a3-2a2ae2dbcce4",
"name": "Spravochnik1",
"date_create": "2019-08-06T09:30:49.355439Z",
"date_end": "2019-08-06T09:29:57Z"
},
"name": "John",
"message": "Hi everyone"
}
]

for nested serialization check full ref here
and for your case add depth = 1
class GeneralSerializer(serializers.ModelSerializer):
status = DictionarySerializer(required=True)
class Meta:
model = None
fields = '__all__'
depth = 1
