Question

我在myProject中的urls.py是

from django.conf.urls import patterns, include, url
from testapp import urls

urlpatterns = patterns('',
    url(r'^', include(urls)),
)

和myApp中的urls.py（称为testapp）是

from django.conf.urls import patterns, include, url
from testapp.forms import UsersForm

urlpatterns = patterns('',
    url(r'^$', 'django.contrib.auth.views.login', {'template_name': 'testapp/templates/login.html', 'authentication_form':'UsersForm'}),
)

我的myProject / templates / login.html是

        <form method="post" action="{% url 'django.contrib/auth.views.login' %}">{% csrf_token%}
            {{form.username.label_tag}}
            {{form.username}}
            {{form.password.label_tag}}
            {{form.password}}
        <input type="submit" value="login" />
        <input type="hidden" name="next" value="{{ next }}" />
        </form>

现在，当我运行server并转到127.0.0.1时，它说

TypeError at /

我正在使用django提供的通用登录视图。为什么它在通用登录视图中的第53行给出了错误？在我的urls.py中，我确实指定了'authentication_form'：'UsersForm'。我是否错误地导入了UsersForm？

Answer 1

您需要传递"authentication_form"的实际表单类，而不是名称"UsersForm"。

Answer 2

清除托马斯的答案，这是对的。
传递表格本身，而不是字符串：

from testapp.forms import UsersForm
url(r'^$', 'django.contrib.auth.views.login', {'template_name': 'testapp/templates/login.html', 'authentication_form':UsersForm}),

Django通用登录视图返回'str object not callable'错误
