做这个demo的前提是你已经配好了python ,django ,djangorestframwork(在我的上一篇博客中有介绍,大家也可以google),mysql-python等。
djangorestframwork的官网点击打开链接http://django-rest-framework.org/
工程目录:
下面开始:
models.py 主要负责数据库对象的映射
''' Created on 2013-9-19 @author: lele ''' from django.db import models # Create your models here. class Student(models.Model): id=models.IntegerField(primary_key=True) Pname= models.CharField(max_length=500) age=models.IntegerField() class Meta: ordering = ('id',)
序列化:
serializers.py
# -*- coding: UTF-8 -*- ''' Created on 2013-9-19 @author: lele ''' from django.forms import widgets from rest_framework import serializers from models import Student,Content class StudentSerializer(serializers.ModelSerializer): mystudentsdetail = serializers.HyperlinkedRelatedField(many=True, view_name='student-detail') class Meta: model = Student fields = ('id', 'Pname','age') id = serializers.IntegerField() # Note: `Field` is an untyped read-only field. Pname= serializers.CharField(max_length=100) age=serializers.IntegerField() def restore_object(self, attrs, instance=None): """ Create or update a new snippet instance. """ if instance: # Update existing instance instance.Panme = attrs['Pname'] instance.id = attrs['id'] instance.age = attrs['age'] return instance # Create new instance return Student(**attrs)
views.py:
''' Created on 2013-9-19 @author: lele ''' from django.http import HttpResponse from models import Student,Content from serializers import StudentSerializer from rest_framework import viewsets class StudentViewSet(viewsets.ModelViewSet): """ This viewset automatically provides `list`, `create`, `retrieve`, `update` and `destroy` actions. Additionally we also provide an extra `highlight` action. """ queryset = Student.objects.all() serializer_class = StudentSerializer修改配置文件:
在settings.py中修改databases
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', # Add 'postgresql_psycopg2', 'mysql', 'sqlite3' or 'oracle'. 'NAME': 'test', # Or path to database file if using sqlite3. # The following settings are not used with sqlite3: 'USER': 'root', 'PASSWORD': '123456', 'HOST': '127.0.0.1', # Empty for localhost through domain sockets or '127.0.0.1' for localhost through TCP. 'PORT': '3306', # Set to empty string for default. } }
REST_FRAMEWORK = { # Use hyperlinked styles by default. # Only used if the `serializer_class` attribute is not set on a view. 'DEFAULT_MODEL_SERIALIZER_CLASS': 'rest_framework.serializers.HyperlinkedModelSerializer', 'DEFAULT_PERMISSION_CLASSES': ( 'rest_framework.permissions.AllowAny', ), 'PAGINATE_BY': 3, #every number in page 'PAGINATE_BY_PARAM': 'page_size', 'MAX_PAGINATE_BY': 100 }
设置访问连接:
在urls.py设置
from django.conf.urls import patterns, include, url from rest_framework import viewsets, routers from views import StudentViewSet router = routers.DefaultRouter() router.register(r'mystudents',StudentViewSet) urlpatterns = patterns('', url(r'^', include(router.urls)), url(r'^api-auth/', include('rest_framework.urls', namespace='rest_framework')), )
就剩最后一步了在mysql数据库中添加 数据
注意:数据库的名字与setting.py中的一致,table的名字格式是:项目名_对象名
例如我的项目名为:djangodemo2 models.py中的model对象名为student ,所以我的表名为:djangodemo2_student
有三个字段 id,Pname ,age 要与serializers.py中的fields字段相同
本例中的字段如下:
运行测试:
在浏览器中输入:http://localhost:8000 即可看到如下页面:
