主要用在view.login函數，不管登錄是否成功，都會設置message變量，然后在login.html顯示
from django.contrib import messages#需要導的包
提供兩個函數
messages.add_message(request,messages.INFO,'要顯示的字符串')
messages.get_messages(request)
默認類型有：（message.INFO）
- DEBUG
- INFO
- SUCCESS
- WARNING
- ERROR
也可以在setting.py中自定義自己的等級標簽
附上我的代碼
def login_2(request):
if request.method == 'POST':
login_form = LoginForm(request.POST)
if login_form.is_valid():
login_name=request.POST['username'].strip()
login_password = request.POST['password']
user = authenticate(username=login_name,password=login_password)
if user is not None:
if user.is_active:
auth.login(request,user)#把此用戶的數據存入session中
print "success"
messages.add_message(request,messages.SUCCESS,'成功登陸了')#使用了django的信息顯示框架 message framework
return HttpResponseRedirect('/userinfo/')
else:
messages.add_message(request,messages.WARNING,"賬號尚未啟動")
else:
messages.add_message(request,messages.WARNING,"登陸失敗")
else:
messages.add_message(request,messages.INFO,"請檢查輸入的字段內容")
else:
login_form = LoginForm()
template = get_template('one/agriculture/login.html')
request_context = RequestContext(request)
request_context.push(locals())
html = template.render(request_context)
return HttpResponse(html)
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>Title</title>
</head>
<body>
{% for message in messages %}
<div class='alert alert-{{message.tags}}'>{{ message }}</div>
{% endfor %}
<!--主要是結合message framework 用-->
<p>登陸我的農商</p>
<form action="/login_2/" method="post">
{% csrf_token %}
<table>
{{ login_form.as_table }}
</table>
<input type="submit" value="登陸" />
</form>
</body>
</html>
