tastypie Django REST framework API [Hello JSON]
tastypie is a good thing.
Haven't test it thoroughly. Gonna need some provement.
Now I will introduct how to use tastepie for newbies.
Let me introduce all the equipments I have to deploy tastypie.
1) linuxmint 13
2) virtualenv ( sudo apt-get install python-virtualenv )
3) install django==1.5 in the virtualenv folder ( ./bin/pip install django==1.5 )
4) install django-tastypie (./bin/pip install django-tastypie )
5) create new project ( ./bin/djangoadmin.py startproject ts2 )
6) get into the 'ts2' folder ( cd ts2 )
7) create new app (../bin/djangoadmin.py startapp myapp NOTICE: folder myapp is at the same folder level as manage.py )
8) edit file ts2/myapp/models.py as following,
from tastypie.utils.timezone import now
from django.contrib.auth.models import User
from django.db import models
from django.template.defaultfilters import slugify class Entry(models.Model):
user = models.ForeignKey(User)
pub_date = models.DateTimeField(default=now)
title = models.CharField(max_length=200)
slug = models.SlugField()
body = models.TextField() def __unicode__(self):
return self.title def save(self, *args, **kwargs):
# For automatic slug generation.
if not self.slug:
self.slug = slugify(self.title)[:50] return super(Entry, self).save(*args, **kwargs)
9) create ts2/myapp/api.py like this,
# myapp/api.py
from tastypie.resources import ModelResource
from models import Entry # Here i corrected it. the docs from tastypieapi.org is
#\ wrong that from myapp.models import Entry class EntryResource(ModelResource):
class Meta:
queryset = Entry.objects.all()
resource_name = 'entry'
10) add 2 rows in the ts2/ts2/settings.py as this,
add 'tastypie' and 'myapp' in the INSTALLED_APPS ,
11) edit ts2/ts2/urls.py ,
from django.conf.urls import patterns, include, url # Uncomment the next two lines to enable the admin:
# from django.contrib import admin
# admin.autodiscover
from myapp.api import EntryResource
entry_resource = EntryResource() urlpatterns = patterns('',
# Examples:
# url(r'^$', 'ts2.views.home', name='home'),
# url(r'^ts2/', include('ts2.foo.urls')), # Uncomment the admin/doc line below to enable admin documentation:
# url(r'^admin/doc/', include('django.contrib.admindocs.urls')), # Uncomment the next line to enable the admin:
# url(r'^admin/', include(admin.site.urls)),
# The normal jazz here...
#(r'^blog/', include('myapp.urls')),
(r'^api/', include(entry_resource.urls)),
)
12) initialize database , forms, and data ( ../bin/python manage.py syncdb )
File struture of this project:
ts2/
|-- db.sqlite3
|-- manage.py
|-- myapp
| |-- api.py
| |-- __init__.py
| |-- models.py
| |-- tests.py
| `-- views.py
`-- ts2
|-- __init__.py
|-- settings.py
|-- urls.py
|-- wsgi.py
13) run server ( ../bin/python manage runserver )
go to http://localhost:8000/api/entry/?format=json
Now you will see this:
This help you to read JSON ! :)
http://json.parser.online.fr/
Isn't good? :P
Before awaring of tastypie, I used orignal JSON parser and 3rd party ORM to do things like REST application works.
I have also heard of django-gap which is more lighter than tastypie.
Gonna have a comparison if possible. :)
Happy Coding!
