FBV 和 CBV
django中请求处理方式有2种:
FBV(function base views)** 就是在视图里使用函数处理请求。
看代码:
urls.py
from django.conf.urls import url, include
# from django.contrib import admin
from mytest import views
urlpatterns = [
# url(r‘^admin/‘, admin.site.urls),
url(r‘^index/‘, views.index),
]
views.py
from django.shortcuts import render
def index(request):
if request.method=="POST":
print('method is :' + request.method)
elif request.method=="GET":
print('method is :' + request.method)
return render(request, "index.html")
注意此处定义的是函数def index(request):
index.html
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>index</title>
</head>
<body>
<form action="" method="post">
<input type="text" name="A" />
<input type="submit" name="b" value="提交" />
</form>
</body>
</html>
上面就是FBV的使用。
CBV(class base views)** 就是在视图里使用类处理请求。
将上述代码中的urls.py 修改为如下:
from mytest import views
urlpatterns = [
# url(r‘^index/‘, views.index),
url(r‘^index/‘, views.Index.as_view()),
]
注:url(r‘^index/‘, views.Index.as_view()), 是固定用法。
将上述代码中的views.py 修改为如下:
from django.views import View
class Index(View):
def get(self, request):
print(‘method is :‘ + request.method)
return render(request, ‘index.html‘)
def post(self, request):
print(‘method is :‘ + request.method)
return render(request, ‘index.html‘)
注:这里是类不在是函数了; 类要继承 View ,类中函数名必须小写。
