Question

实际上，当我使用用户名注册时，它会重定向到注册完成页面。但是当我使用该用户名登录时，它会抛出表单错误。因此，当我使用我创建的用户名登录时，它会显示

“您的用户名和密码不匹配。请重试”

（我写的是在login.html中显示form.errors）

login.html

{% extends "base.html" %}

{% block content %}

{% if form.errors %}
<p>Your username and password didn't match. Please try again.</p>
{% endif %}

<form method="post" action="{% url 'django.contrib.auth.views.login' %}">
{% csrf_token %}
<table>
<tr>
<td>{{ form.username.label_tag }}</td>
<td>{{ form.username }}</td>
</tr>
<tr>
<td>{{ form.password.label_tag }}</td>
<td>{{ form.password }}</td>
</tr>
</table>

<input type="submit" value="login" />
<input type="hidden" name="next" value="{{ next }}" />
</form>

{% endblock %}

registration.html

<html>
<head>
  <title>Register</title>
</head>   

<body>
  <h2>Register</h2>
  <form action="/accounts/register/" method="POST">{% csrf_token %}
     <table>
        {{form.as_table}}
     </table>

  <p>
     <input type="submit" value="Submit">
  </p>
  </form>   
</body>
</html>

urls.py

enter code here
from django.conf.urls import patterns, include, url
from frm.views import main,forum,thread
from frm.views import reply,new_thread,profile,post
from django.conf import settings
from django.contrib import admin
from django.conf.urls import *
from django.contrib.auth.views import login
admin.autodiscover()

urlpatterns = patterns('',
url(r'^$',main),
url(r'^forum/(?P<pk>\w+)/$',forum  ),
url(r'^thread/(?P<pk>\w+)/$',thread ),
url(r'^post/(new_thread|reply)/(\d+)',post),
url(r'^new_thread/(\d+)/$',new_thread),
url(r'^reply/(\d+)/$',reply),
url(r'^profile/(?P<pk>\w+)/$',profile),

# Examples:
# url(r'^$', 'forum.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^accounts/',include('registration.backends.default.urls')),

url(r'^admin/', include(admin.site.urls)),
)

您可以通过多种方式访问模板中的错误。尝试更改：

{% if form.errors %}
  <p>Your username and password didn't match. Please try again.</p>
{% endif %}

为：

{% if form.errors %}
  {{ form.errors }}
  <br /><br />

  {% if form.non_field_errors %}
    {% for error in form.non_field_errors %}
      {{ error }}
    {% endfor %}

    <br /><br />
    a nicer way:<br />
    {{ form.non_field_errors.as_ul }}

  {% endif %}

  <br /><br />
  form username errors:<br />
  {{ form.username.errors }}

  <br /><br />
  form password errors:<br />
  {{ form.password.errors }}
{% endif %}

这是一个好的开始。您还需要向访问者显示错误。将您的label_tag更改为

<td>{{form.username.errors }}<br />{{ form.username.label_tag }}</td>

和

<td>{{form.password.errors }}<br />{{ form.password.label_tag }}</td>

在django-registration我没有得到任何确认链接？
