Django DRF+ EmberJS2.6 related model data - django

Question

I have django app that handle restAPIs with following JSON response, also i have ember app with django-ember-adapter. The problem is i can not get related items in the sub route(http://localhost:8000/api/projects/4/tasks) of API. I can get projects by http://localhost:8000/api/projects/4. Am i have to include task in project's django model in API?, I have tried using links in serializer but seems it's not working.
How do i get project's tasks successfully?
json response on http://localhost:8000/api/projects/4 i can get this by this.store.findRecord('project', params.project_id):
{
"id": 4,
"title": "test1 project",
"description": "some project",
"owner": "test1"
}
json response on http://localhost:8000/api/projects/4/tasks:
{
"count": 2,
"next": null,
"previous": null,
"results": [
{
"id": 5,
"title": "4th",
"description": "4tg description"
},
{
"id": 6,
"title": "",
"description": ""
}
]
}
django models:
class Project(models.Model):
"""Canara project """
title = models.CharField(max_length=50, blank=True, default='')
created = models.DateTimeField(auto_now_add=True)
description = models.CharField(max_length=255, blank=True)
active = models.BooleanField(default=True)
owner = models.ForeignKey(User, related_name='projects', null=True)
def __unicode__(self):
return self.title
class Task(models.Model):
title = models.CharField(max_length=55, blank=True)
description = models.CharField(max_length=255, blank=True)
created = models.DateTimeField(auto_now_add=True)
due_date = models.DateField(blank=True, null=True)
assign = models.ForeignKey(User, null=True)
project = models.ForeignKey(Project, null=True)
serializer:
class ProjectViewSet(ModelViewSet):
"""
API endpoint for project
"""
authentication_classes = [TokenAuthentication, SessionAuthentication]
permission_classes = (IsAuthenticated, IsOwner)
serializer_class = ProjectSerializer
def get_queryset(self):
"""
Get user's project
"""
return Project.objects.filter(members__member=self.request.user)
def perform_create(self, serializer):
"""
Set user as an owner when create project
"""
serializer.save(owner=self.request.user)
class TaskViewSet(ModelViewSet):
"""
API for task
"""
authentication_classes = [TokenAuthentication, SessionAuthentication]
permission_classes = [IsAuthenticated,]
serializer_class = TaskSerializer
queryset = Task.objects.all()
ember app's project model
export default Model.extend({
title: attr(),
description: attr(),
});
ember app's task model
export default Model.extend({
title: attr(),
description: attr(),
due_date: attr('date'),
assign: belongsTo('user'),
project: belongsTo('project')
});
Update
I have tried embedded record mixin but no luck
in the serializer:
class ProjectSerializer(serializers.ModelSerializer):
owner = serializers.ReadOnlyField(source='owner.username')
class Meta:
model = Project
fields = ('id', 'title', 'description', 'owner', 'tasks')
def create(self, validated_data):
"""
Create project using given validated data
"""
return Project.objects.create(**validated_data)
def update(self, instance, validated_data):
"""
Update project title description
"""
instance.title = validated_data.get('title', instance.title)
instance.description = validated_data.get(
'description', instance.description)
instance.save()
class TaskSerializer(serializers.ModelSerializer):
project = serializers.PrimaryKeyRelatedField(queryset=Project.objects.all())
class Meta:
model = Task
fields = ('id', 'title', 'description', 'due_date', 'assign', 'project')
def create(self, validated_data):
return Task.objects.create(**validated_data)
def update(self, instance, validated_data):
instance.title = validated_data.get('title', instance.title)
instance.description = validated_data.get('description', instance.description)
instance.due_date = validated_data.get('due_date', instance.due_date)
instance.assign = validated_data.get('assign', instance.assign)
i've tried links in this way:
import DRFSerializer from './drf';
export default DRFSerializer.extend({
normalizeFindAllResponse(store, primaryModelClass, payload, id, requestType) {
console.log(payload)
payload.links: {
tasks: tasks
};
});
return this._super(...arguments);
}
});
