问题描述
我的myProject中的urls.py是
from django.conf.urls import patterns,include,url
from testapp import urls
urlpatterns = patterns('',
url(r'^',include(urls)),
)
$ c $我的myApp(称为testapp)中的urls.py是来自django.conf.urls导入模式的包含来自testapp.forms的url
import UsersForm
urlpatterns = patterns('',
url '^ $','django.contrib.auth.views.login',{'template_name':'testapp / templates / login.html','authentication_form':'UsersForm'}),
)
我的myProject / templates / login.html是
< form method =postaction ={%url'django.contrib / auth.views.login'%}> {%csrf_token%}
{ form.username.label_tag}}
{{form.username}}
{{form.password.label_tag}}
{{form.pas sword}}
< input type =submitvalue =login/>
< input type =hiddenname =nextvalue ={{next}}/>
< / form>
现在,当我运行服务器并转到127.0.0.1它说
Type $ /
'str'对象不可调用
请求方法:GET

我正在使用django提供的通用登录视图。为什么在通用登录视图中的第53行给我一个错误?在我的urls.py中,我确实指定了'authentication_form':'UsersForm'。我导入用户窗体错误吗?
解决方案要清除托马斯的答案,那是正确的。
传递表单本身,而不是字符串:
from testapp.forms import UsersForm
url(r'^ $','django.contrib.auth.views.login',{'template_name':'testapp / templates / login.html','authentication_form':UsersForm}),
My urls.py in myProject is
from django.conf.urls import patterns, include, url
from testapp import urls
urlpatterns = patterns('',
url(r'^', include(urls)),
)
and my urls.py in myApp (called testapp) is
from django.conf.urls import patterns, include, url
from testapp.forms import UsersForm
urlpatterns = patterns('',
url(r'^$', 'django.contrib.auth.views.login', {'template_name': 'testapp/templates/login.html', 'authentication_form':'UsersForm'}),
)
My myProject/templates/login.html is
<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>
Now, when I runserver and go to 127.0.0.1 it says
TypeError at /
'str' object is not callable
Request Method: GET

I am using the generic login view which django provides. Why is it giving me an error at line 53 in the generic login view? In my urls.py I did specify that 'authentication_form':'UsersForm'. Am I importing the UsersForm incorrectly?
解决方案 To clear out Thomas's answer, which is right.
Pass the form itself, not the string:
from testapp.forms import UsersForm
url(r'^$', 'django.contrib.auth.views.login', {'template_name': 'testapp/templates/login.html', 'authentication_form':UsersForm}),
