cvb 即class view 和funtion view 两种方式 发送get和post请求
前后端不分离的写法，定义一个html(form.html)，在view中写逻辑（cvb&fvb）
备注：需要注意csrf的问题，如果多次提交重复的数据会报403，解决办法两种
1.在settings.py-MIDDLEWARE-将csrf（第四行）注释掉
2.在form.html中写{% csrf_token%}
form.html的代码
<!DOCTYPE html> <html lang="en"> <head> <meta charset="UTF-8"> <title>Title</title> </head> <body> <form action="/add_article/" method="post">
{% csrf_token %}
title:<input type="text" name="title"> desc:<input type="text" name="desc"> content:<input type="text" name="content"> category:<select name="category"> {% for c in categorys %} <option value="{{ c.id }}">{{ c.name }}</option> {% endfor %} </select> <input type="submit" value="提交"> </form> </body> </html>
views.py中的代码
#function fvb方式 def add_article(request): if request.method == ‘GET‘: categorys = Category.objects.all() return render(request,‘form.html‘,locals()) else: title = request.POST.get(‘title‘) desc = request.POST.get(‘desc‘) content = request.POST.get(‘content‘) category = request.POST.get(‘category‘) article = Article(title=title,desc=desc,category_id=category,content=content) article.save() return HttpResponseRedirect(‘/blog‘)#重定向 #class cvb方式 class ArticleView(View): def get(self,request): categorys = Category.objects.all() return render(request, ‘form.html‘, locals()) def post(self,request): title = request.POST.get(‘title‘) desc = request.POST.get(‘desc‘) content = request.POST.get(‘content‘) category = request.POST.get(‘category‘) article = Article(title=title, desc=desc, category_id=category, content=content) article.save() return HttpResponseRedirect(‘/blog‘) # 重定向
urls.py
from django.contrib import admin from django.urls import path from user.views import index,test,blog,detail,add_article,ArticleView urlpatterns = [ path(‘admin/‘, admin.site.urls), path(‘index/‘, index),#添加访问的url,index/可自定义,index是views.py中的方法 path(‘test/‘, test), path(‘blog/‘, blog), # path(‘category/<int:id>‘, category), path(‘detail/‘, detail), # path(‘add_article/‘, add_article),#fvb方式 path(‘add_article/‘, ArticleView.as_view()),#cvb方式 ]
