I am currently using the default CRUD operations provided by django-rest-framework. It works well with normal models but one of my model has many-many relation with another tag model. Here is the code for models
class ActivityType(models.Model):
title = models.CharField(max_length=200)
slug = models.CharField(max_length=250,unique=True)
def __unicode__(self):
return self.slug
class Activity(models.Model):
owner = models.ForeignKey('auth.user')
title = models.CharField(max_length=200)
slug = models.CharField(max_length=250,unique=True)
description = models.TextField()
tags = models.ManyToManyField(ActivityType)
created = models.DateTimeField(auto_now_add=True, blank=True)
def __unicode__(self):
return self.slug
What i want to know is what is the best method to integrate DRF with the same, if possible without writing all CRUD operations from scratch.
In your serializers.py
from rest_framework import serializers
from rest_framework import generics
from models import Activity
from models import ActivityType
class ActivityTypeSerializer(serializers.ModelSerializer):
class Meta:
model = ActivityType
fields = ('id', 'title', 'slug')
class ActivitySerializer(serializers.ModelSerializer):
tags = ActivityTypeSerializer(many=True, read_only=True)
class Meta:
model = Activity
fields = ('id', 'owner', 'title', 'slug', 'description', 'tags', 'created')
in your views.py
from rest_framework import viewsets
from serializers import ActivitySerializer
from serializers import ActivityTypeSerializer
from models import Activity
from models import ActivityType
class ActivityViewSet(viewsets.ModelViewSet):
queryset = Activity.objects.all()
serializer_class = ActivitySerializer
class ActivityTypeViewSet(viewsets.ModelViewSet):
queryset = ActivityType.objects.all()
serializer_class = ActivityTypeSerializer
and in your urls.py
from rest_framework.urlpatterns import format_suffix_patterns
from rest_framework import routers, serializers, viewsets
from rest_framework import generics
from rest_framework import viewsets, routers
from your_app.views import ActivityTypeViewSet
from your_app.views import ActivityViewSet
router = routers.DefaultRouter()
router.register(r'activitytypes', ActivityTypeViewSet)
router.register(r'activities', ActivityViewSet)
Also make sure the restframework urls are included as described in docs
urlpatterns = patterns('',
# your other urls
url(r'^api/$', include('rest_framework.urls', namespace='rest_framework')),
url(r'api/accounts/', include('rest_framework.urls', namespace='rest_framework')),
)
