Python Monitor Water Falls(2)Python RESTful Service
Prepare the package
>pip install django
>pip install djangorestframework
browsable API
>pip install markdown
filter support
>pip install django-filter
Start up the project
>django-admin.py startproject restful_api
>cd restful_api/
Create a quick start
>django-admin.py startapp quickstart
Sync the database for the first time
>python manage.py migrate
Create a user admin and password password123.
>python manage.py createsuperuser --email [email protected] --username admin
It will ask me for password.
First Example to Build RESTful Service on that.
Add restful_api/quickstart/serializers.py
from django.contrib.auth.models import User, Group
from rest_framework import serializers
class UserSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = User
fields = ('url', 'username', 'email', 'groups')
class GroupSerializer(serializers.HyperlinkedModelSerializer):
class Meta:
model = Group
fields = ('url', 'name')
Viewsets to Have the Response in restful_api/quickstart/views.py
# -*- coding: utf-8 -*-
from __future__ import unicode_literals
from django.contrib.auth.models import User, Group
from rest_framework import viewsets
from restful_api.quickstart.serializers import UserSerializer, GroupSerializer
class UserViewSet(viewsets.ModelViewSet):
"""
API endpoint for users
"""
queryset = User.objects.all().order_by('-date_joined')
serializer_class = UserSerializer
class GroupViewSet(viewsets.ModelViewSet):
"""
API endpoint for groups
"""
queryset = Group.objects.all()
serializer_class = GroupSerializer
Add the URL mapping in restful_api/urls.py
from django.conf.urls import url, include
from rest_framework import routers
from restful_api.quickstart import views
router = routers.DefaultRouter()
router.register(r'users', views.UserViewSet)
router.register(r'groups', views.GroupViewSet)
urlpatterns = [
url(r'^', include(router.urls)),
url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework'))
]
Add the settings there in restful_api/settings.py
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'rest_framework',
]
Start the RESTful Service
>python manage.py runserver
Test that from CURL
>curl -H 'Accept: application/json;indent=4' http://localhost:8000/users/
[
{
"url": "http://localhost:8000/users/1/",
"username": "admin",
"email": "[email protected]",
"groups": []
}
]
Test that from Browsable API
http://localhost:8000/
That is a very nice beginning.
