我正在尝试使用django-registration,django-registration-defaults和django-email-usernames为我的django应用程序实现注册和登录系统。
一切安装得很好。 django-email-usernames提供自定义登录表单,允许将电子邮件用作用户名。这是表单的代码。
from django import forms
from django.utils.translation import ugettext_lazy as _
from django.contrib.auth import authenticate
...
class EmailLoginForm(forms.Form):
email = forms.CharField(label=_(u"Email"), max_length=75, widget=forms.TextInput(attrs=dict(maxlength=75)))
password = forms.CharField(label=_(u"Password"), widget=forms.PasswordInput)
def clean(self):
# Try to authenticate the user
if self.cleaned_data.get('email') and self.cleaned_data.get('password'):
user = authenticate(username=self.cleaned_data['email'], password=self.cleaned_data['password'])
if user is not None:
if user.is_active:
self.user = user # So the login view can access it
else:
raise forms.ValidationError(_("This account is inactive."))
else:
raise forms.ValidationError(_("Please enter a correct username and password. Note that both fields are case-sensitive."))
return self.cleaned_data
在django-registration的urls.py中,有登录页面的模式。它使用默认的django.contrib.auth.views.login视图进行登录。
所以在urls.py中我得到了这个:
from django.conf.urls.defaults import *
from django.views.generic.simple import direct_to_template
from django.contrib.auth import views as auth_views
from registration.views import activate
from registration.views import register
from email_usernames.forms import EmailLoginForm
...
url(r'^login/$', auth_views.login, {'template_name': 'registration/login.html', 'authentication_form': EmailLoginForm}, name='auth_login'),
...
django.contrib.auth.views.login接受要使用的template_name和表单。正如你在上面所看到的那样,我正在传递这些内容。我正在设置模板并将authentication_form设置为django-email-usernames提供的模板。
然后当浏览到登录页面时,我收到以下错误:
模板错误
在模板/Users/Amir/.virtualenvs/scvd/lib/python2.6/site-packages/registration_defaults/templates/registration/login.html中,第16行出错 渲染时捕获AttributeError:'WSGIRequest'对象没有属性'get'

9 <table>
10 <tr>
11 <td>{{ form.username.label_tag }}</td>
12 <td>{{ form.username }}</td>
13 </tr>
14 <tr>
15 <td>{{ form.password.label_tag }}</td>
16 <td>{{ form.password }}</td>
17 </tr>
18 </table>
19 <p><a href="{% url auth_password_reset %}">Forgot</a> your password? <a href="{% url registration_register %}">Need an account</a>?</p>
20
21 <input type="submit" value="login" />
22 <input type="hidden" name="next" value="{{ next }}" />
23 </form>
24
25 {% endblock %}

我很困惑。我很确定我正确配置了urls.py配置。我不理解模板中第16行({{form.password}})发生的错误。
请让我知道我还能提供什么来澄清我的问题。非常感谢你的帮助。

似乎你的clean()不是那么清楚
user = authenticate(username=self.cleaned_data['email'], password=self.cleaned_data['password'])
有.get缺失
user = authenticate(username=self.cleaned_data.get['email'], password=self.cleaned_data.get['password'])
使用
是一种好习惯 def clean(self):
x = self.cleaned_data.get("username")
y = self.cleaned_data.get("password")
然后你可以使用
user = authenticate(username=x, password=y)
