项目级-使用Django做api踩过的坑...
第一步
# 安装 'django_filters','rest_framework', pip3 install django_filters pip3 install rest_framework
rest_framework与django_filters使用不在赘述,请参照Django REST Framework教程:快速入门 Rest-framework快速实现增删改查及筛选
第二步
在setting中配置INSTALLED_APPS 切记
setting加入配置
REST_FRAMEWORK = { 'DEFAULT_PERMISSION_CLASSES':[ 'rest_framework.permissions.DjangoModelPermissionsOrAnonReadOnly' ], 'DEFAULT_PAGINATION_CLASS':'rest_framework.pagination.PageNumberPagination', # 'PAGE_SIZE':3 (可先注释,加页码会用到) }
第三步
在应用目录下创建 query_filter.py 与 serializers.py文件
# Author:jum # -*- coding: utf-8 -*- # @Time : 2020-03-10 9:20 # @File : query_filter.py # @Software: PyCharm """筛选条件""" # fields中为可筛选字段
# 切记图片字段不可加入筛选字段
from django_filters import rest_framework as filters from apps.user_blog.models import * class BussFilter(filters.FilterSet): class Meta: model = Buss fields = ['id', 'name'] class GoodsFilter(filters.FilterSet): class Meta: model = Goods fields = ['id', 'buss_cate',]
# Author:jum # -*- coding: utf-8 -*- # @Time : 2020-03-09 14:22 # @File : serializers.py # @Software: PyCharm # 用于返回json数据 # fields 中设置你将展示的字段 from rest_framework import serializers from apps.user_blog.models import * class StudentSerializers(serializers.ModelSerializer): class Meta: model = User # 指定的模型类 fields = ('name', 'job_num') # 需要序列化的属性 class BussSerializers(serializers.ModelSerializer): class Meta: model = Buss # 指定的模型类 fields = ('id', 'name', 'pwd', 'weight', 'create_time', 'update_time') # 需要序列化的属性 class GoodsSerializers(serializers.ModelSerializer): class Meta: model = Goods # 指定的模型类 fields = ('id', 'buss_cate', 'name', 'tp', 'price', 'buys_count', 'weight', 'create_time')
第四步:
配置url,填充view
#view.py from django.shortcuts import render from rest_framework import viewsets from apps.user_blog.models import * from .serializers import StudentSerializers, BussSerializers,GoodsSerializers from .query_filter import BussFilter,GoodsFilter from django_filters import rest_framework as filters # Create your views here. class StudentViewSet(viewsets.ModelViewSet): # 指定结果集并设置排序 # queryset 为查询集,可自定义 queryset = User.objects.all() # 指定序列化的类 serializer_class = StudentSerializers class BussViewSet(viewsets.ModelViewSet): # 指定结果集并设置排序 # queryset 为查询集,可自定义 queryset = Buss.objects.all() # 查询出所有商家 # 指定序列化的类 serializer_class = BussSerializers #加入筛选字段 filter_backends = (filters.DjangoFilterBackend,) filter_class = BussFilter class GoodsViewSet(viewsets.ModelViewSet): # 指定结果集并设置排序 # queryset 为查询集,可自定义 queryset = GoodsSerializers.objects.all() # 查询出所有商家 # 指定序列化的类 serializer_class = GoodsSerializers filter_backends = (filters.DjangoFilterBackend,) filter_class = GoodsFilter # Create your views here.
#url.py from django.conf.urls import include, url from rest_framework import routers from . import views # 定义路由地址 route = routers.DefaultRouter() # 注册新的路由地址 route.register(r'user', views.StudentViewSet) route.register(r'buss', views.BussViewSet) route.register(r'goods', views.GoodsViewSet) # 注册上一级的路由地址并添加 urlpatterns = [ url(r'^', include(route.urls)), ]
最后,如过项目发布后没有静态文件 以Nginx为例
为rest_framework添加静态文件指向
location /static/rest_framework/ { alias /usr/local/lib/python3.5/distpackages/rest_framework/static/rest_framework/;}
