Django表单
GET方法请求处理
在testdjango项目中，创建一个search.py文件，文件内容：
from django.http import HttpResponse
from django.shortcuts import render_to_response
def search_from (requset) :return render_to_response('search_from.html' )
def search (request) :'utf-8'
if 'q' in request.GET:
message = '你搜索的内容为：' + request.GET['q' ]
else :
message = '你提交了空表单'
return HttpResponse(message)
在templates目录下创建一个search_from.html的文件，文件内容：
<!DOCTYPE html>
<html lang ="en" >
<head >
<meta charset ="UTF-8" >
<title > Title</title >
</head >
<body >
<form action ="/search" method ="get" >
<input type ="text" name ="q" />
<input type ="submit" value ="搜索" />
</form >
</body >
</html > 在testmodel/urls.py文件下，配置url的路径：
urlpatterns = [
...
url(r'^search_from/' , search.search_from),
url(r'^search/' , search.search),
...
]在浏览器中输入127.0.0.1:8000/search_from，显示search_from.html的内容，在输入框中输入数据，显示如下：
点击提交，显示如下：
POST方法提交表单数据处理
在templates目录下创建一个search_from_post.html的文件，文件内容为：
<!DOCTYPE html>
<html lang ="en" >
<head >
<meta charset ="UTF-8" >
<title > Title</title >
</head >
<body >
<form action ="/search_post/" method ="post" >
{% csrf_token %}
<input type ="text" name ="q" />
<input type ="submit" value ="搜索" />
</form >
<p > {{ content }} </p >
</body >
</html > 备注：form表单的action，如果写成”/search_post”，会报错，如：
RuntimeError at /search_post
You called this URL via POST, but the URL doesn't end in a slash and you have APPEND_SLASH set . Django can't redirect to the slash URL while maintaining POST data. Change your form to point to 127.0 .0 .1 :8000 /search_post/ (note the trailing slash), or set APPEND_SLASH=False in your Django settings.写成”/search_post/”就好了。
在search.py文件创建一个方法search_from_post，如：
from django.shortcuts import render
def search_from_post (request) :'content' ] = ''
if request.POST:
context['content' ] = request.POST['q' ]
print(context)
return render(request=request, template_name='search_from_post.html' , context=context)
在项目的urls.py文件，配置url，如：
urlpatterns = [
...
url(r'^search_post/' , search.search_from_post),
...
]
在浏览器中输入127.0.0.1:8000/search_post/，显示：
在输入框输入王者荣耀，点击搜索，显示
