Django 模板错误?
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。
一切都安装得很好。 django-email-usernames 提供了一个自定义登录表单,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 template_name 和要使用的表单。正如您在上面看到的那样,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 提供的形式。
然后,当浏览到登录页面时,出现以下错误:
TemplateSyntaxError at /accounts/login/ 渲染时捕获 AttributeError:“WSGIRequest”对象没有属性“get”
模板错误

21 <input type="submit" value="login" />
22 <input type="hidden" name="next" value="{{ next }}" />
23 </form>
24
25 {% endblock %}

我陷入困境。我很确定我的 urls.py 配置正确。我不明白模板中第 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。非常感谢您提前提供的帮助。
I am trying to implement a registration and login system for my django app using django-registration, django-registration-defaults, and django-email-usernames.
Everything installed just fine. django-email-usernames provides a custom login form which allows an email to be used as the username. Here is the code for the form.
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
In the urls.py of the django-registration, there is pattern for the login page. It uses the default django.contrib.auth.views.login view for the login.
So in urls.py I got this:
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/
The django.contrib.auth.views.login takes in a template_name and form to use. I'm passing those in as you can see above. I'm setting the template and setting the authentication_form to be the one provided by the django-email-usernames.
Then when browse to the login page I get the following error:
TemplateSyntaxError at /accounts/login/
Caught AttributeError while rendering: 'WSGIRequest' object has no attribute 'get'
Template error
In template /Users/Amir/.virtualenvs/scvd/lib/python2.6/site-packages/registration_defaults/templates/registration/login.html, error at line 16

6 {% endif %}

8 <form method="post" action="{% url django.contrib.auth.views.login %}">{% csrf_token %}
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 %}

I'm pretty stuck. I am pretty sure I did urls.py configuration correctly. I don't understand the erro that is happening with line 16 ({{ form.password }}) in the template.
Please let me know what else I can provide to clarify my question. Thank you so much for your help in advance.

似乎你的 clean() 不太清楚,
有 .get 丢失,
这是很好的使用习惯
,那么你可以使用
Seems that your clean() is not so clear
there is .get missing
it's good practice to use
then you can use
