django-auth登录不能正常工作

my forms.py:

from django import forms
from django.contrib.auth import authenticate, get_user_model
from django.contrib.auth.models import User
from django.forms import ModelForm
from django.utils.text import capfirst
from .models import Classname, Sectionname, Teachername, Attendancename
class AuthenticationForm(forms.Form):
    username = forms.CharField(max_length=20)
    password = forms.CharField(widget=forms.PasswordInput)
    error_messages = {
        'invalid_login': ("Please enter a correct %(username)s and password."
                          "Note that both fields may be case-sensitive."),
        'inactive': ("This account is inactive"),
    }
    def __init__(self, request=None, *args, **kwargs):
        self.request = request
        self.user_cache = None
        super(AuthenticationForm, self).__init__(*args, **kwargs)
        UserModel = get_user_model()
        self.username_field = UserModel._meta.get_field(UserModel.USERNAME_FIELD)
        if self.fields['username'].label is None:
            self.fields['username'].label = capfirst(self.username_field.verbose_name)
    def clean(self):
        username = self.cleaned_data.get('username')
        password = self.cleaned_data.get('password')
        if username and password:
            self.user_cache = authenticate(username=username, password=password)
            if self.user_cache is None:
                raise forms.ValidationError(
                    self.error_messages['invalid_login'],
                    code='invalid_login',
                    params={'username': self.username_field.verbose_name},
            )
            else:
                self.confirm_login_allowed(self.user_cache)
        return self.cleaned_data
     def confirm_login_allowed(self, user):
        if not user.is_active:
            raise forms.ValidationError(
                self.error_messages['inactive'],
                code='inactive',
                )
    def get_user_id(self):
        if self.user_cache:
            return self.user_cache.id
        return None
    def get_user(self):
        return self.user_cache

views.py:

@csrf_protect
@never_cache
def login(request, template_name='login.html',
      authentication_form=AuthenticationForm,
      extra_context=None):
    if request.method == "POST":
        form = authentication_form(request, data=request.POST)
        if form.is_valid():
            return HttpResponseRedirect(reverse('student:mains'))
        else:
            print(form.errors)  
    else:
        form = authentication_form(request)
    context = {
        'form': form,
    }
    return TemplateResponse(request, template_name, context)

my login template:

<html>
<head><title>Login</title></head>
<strong> Mysite Login </strong>
<br><br>
<h3> Please Enter your credentials carefully </h3>
<body>
{% if form.errors %}
    <p>NOT VALID</p>
    {% for errors in form.errors %}
        {{ errors }}
    {% endfor %}
{% endif %}
<form method="post">
    {% csrf_token %}
    <label>Username: </label>
    <input type="text">
    <br>
    <label>Password: </label>
    <input type="password">
    <br>
    <input type="submit" value="Login">
</form>
</body>     
</html>

我的urls . py:

from django.conf.urls import url, patterns
from django.contrib.auth import views as auth_views
from . import views
urlpatterns = [
    url(r'^register/$', views.register, name='register'),
    url(r'^login/$', views.login, name='login'),
    url(r'^logout/$', views.logout, name='logout'),
    url(r'^password_change/$', auth_views.password_change, {'template_name': 'password_change_form.html', 'post_change_redirect': '/stu/password_change/done/'}, name="password_change"),
    url(r'^password_change/done/$', auth_views.password_change_done, {'template_name': 'password_change_done.html'}, name="password_change_done"),
    url(r'^restricted/', views.restricted, name='restricted'),
    url(r'^mains/', views.mains, name = 'mains'),
]

我正在尝试在我的项目上实现django认证。我阅读了一些文档，并制作了上面的认证视图和表单。

问题是，当我提交我的登录表单与正确的凭据，它不重定向到我的视图中指定的重定向位置。它不做任何事情。

这是我想做的正确的方式吗?因为我这里没有使用模型形式。

请建议我改正的方法…

谢谢!提前…

仍然面临同样的问题…

修改如下:

<form method="post">
<label>Username: </label>
<input name="name">
<label>Password: </label>
<input name="phone">

<form method="post" action="{% url 'login_url_name' %}">
<label>Username: </label>
<input name="username">
<label>Password: </label>
<input name="password">

调试建议:

确保你在提交表单时点击了正确的视图。如何?在login()的开头添加调试日志¹。如果您在提交时没有看到日志记录，请确保将<form>的action属性设置为正确的URL。
确保表单通过is_valid()测试。在视图的if form.is_valid():分支中添加调试日志。如果不能工作，请确保凭证正确。转储request.POST，看看表单提交的数据可能有什么问题。

¹调试日志可能是代码中的一个简单的Exception("HEYY!!")。目的很简单，就是看看代码是否到达了有问题的分支。如果你看到Django对你大喊大叫，你就知道它是正确的了。
