form.has_errors标签不起作用 [英] form.has_errors tag not working
问题描述
我正在使用Django 1.2.3.我的网站使用 django.contrib.auth.views.login 具有登录功能.输入正确的用户名和密码后，用户便可以登录.但是， form.has_errors 无法正常工作，即，如果输入的登录凭据不正确，我不会看到错误消息.我的template/registration中的login.html如下:
Im using Django 1.2.3. I have login functionality in my site using django.contrib.auth.views.login. The user is able to login after entering correct username and password. But, form.has_errors is not working i.e. if the login credentials entered are incorrect i dont see the error message. My login.html in templates/registration is as follows :
<html>
<head>
<title>Login</title>
</head>
<body>
<h1>User Login</h1>
{% if form.has_errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
<form method="post" action=".">
{% csrf_token %}
<p><label for="id_username">Username:</label> {{ form.username }}</p>
<p><label for="id_password">Password:</label> {{ form.password }}</p>
<input type="hidden" name="next" value="/" />
<input type="submit" value="login" />
</form>
</body>
</html>
有什么方法可以解决此问题?
Any way to fix this problem?
请帮助谢谢.
推荐答案
A Form object does have an errors attribute, read the docs for more information:
{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}
显然， has_errors 在Django 0.95中有效，但至少在1.0以上版本无效(因为它已替换为 errors ).[参考]
Apparently has_errors was valid in Django 0.95 but not from at least 1.0 upwards (as it was replaced with errors). [reference]
