1.创建程序并初始化数据库:
models.py中的内容:
from django.db import models # Create your models here. class Category(models.Model): """ 文章分类 """ name = models.CharField(verbose_name='分类',max_length=32) class Article(models.Model): """ 文章表 """ category = models.ForeignKey(verbose_name='分类',to='Category',null=True, blank=True,on_delete=models.PROTECT) #使用to做模型关联 title = models.CharField(verbose_name='标题', max_length=32) summary = models.CharField(verbose_name='简介', max_length=255) content = models.TextField(verbose_name='文章内容')
运行命令:
makemigrations 命令
"D:Program FilesJetBrainsPyCharm 2020.1in unnerw64.exe" D:EvnshulalaScriptspython.exe "D:Program FilesJetBrainsPyCharm 2020.1pluginspythonhelperspycharmdjango_manage.py" makemigrations d:/PycharmProjects/hula #创建表
migrate 命令
"D:Program FilesJetBrainsPyCharm 2020.1in unnerw64.exe" D:EvnshulalaScriptspython.exe "D:Program FilesJetBrainsPyCharm 2020.1pluginspythonhelperspycharmdjango_manage.py" migrate d:/PycharmProjects/hula #同步表
2.接口:实现访问接口时,创建一个文章类型
2.1. 配置url
from django.contrib import admin from django.urls import path from api import views #导入api应用中的views.py文件 urlpatterns = [ path('admin/', admin.site.urls), path('drf/category/', views.DrfCategoryView.as_view()), # 文章分类的url配置及视图函数 ]
2.2. 视图内容
from rest_framework.views import APIView #导入rest_framework的APIView from rest_framework.response import Response #导入rest_framework的 Response #使用drf中的APIView写相应的get、post、delete、put等响应,使用rest_framework中的response #文章分类的View class DrfCategoryView(APIView): """ 文章分类的drf相关接口 """ def get(self,request,*args,**kwargs): #处理get请求 data = [ { "id":1, "title":"震惊了...王洋居然...", "content":"..." }, { "id": 2, "title": "震惊了...王洋居然...", "content": "..." }, { "id": 3, "title": "震惊了...王洋居然...", "content": "..." }, { "id": 4, "title": "震惊了...王洋居然...", "content": "..." }, ] return Response(data) #使用rest_framework的 Response
def post(self, request, *args, **kwargs): #处理post请求,加上*args, **kwargs后可以处理url路径后的参数,建议加上
"""
增加一条分类信息
:param request:
:param args:
:param kwargs:
:return:
"""
# name = request.Post.get('...')
name = 'IT'
models.Category.objects.create(name=name) #使用create函数创建新加一条数据
return Response('成功')
def put(self, request, *args, **kwargs): #处理put请求
pass
def delete(self, request, *args, **kwargs): #处理delete请求
pass
2.3.访问接口url,如:http://192.168.1.103:8000/drf/category/
使用postman或者requests或者其他接口访问工具
