Question

我在django中遇到了问题：

'str' object is not callable

代码：

urls.py App Usuarios：

from django.conf.urls import patterns, include, url
from django.contrib.auth.views import login, logout_then_login
from usuarios.views import Registro

urlpatterns = patterns('',
    url(r'^login/$', 'django.contrib.auth.views.login', {'template_name':'registration/login.html'},
                name='login'),

        url(r'^cerrar/$', 'django.contrib.auth.views.logout_then_login', 
        name='logout'),

    url(r'^registro/$', 'Registro', name='registro'),
)

views.py

from django.http import HttpResponse, HttpResponseRedirect
from django.contrib.auth import authenticate, login, logout
from django.core.context_processors import csrf

#importar el formulario de registro
from usuarios.forms import RegistroUsuario


def Registro(request):
    if request.user.is_anonymous():
        if request.method == 'POST':
        form = RegistroUsuario(request, POST)
        if form.is_valid():
                    form.save()
            return HttpResponse('Usuario creado sin problemas.')
            else:
        form = RegistroUsuario()
        context = {}
        context.update(csrf(request))
        context['form'] = form
        #pasar el context al template
        return render_to_response('registro.html', context)
    else:
        return HttpResponseRedirect('/')

forms.py：

from django import forms
from django.contrib.auth.models import User
from django.contrib.auth.forms import UserCreationForm


class RegistroUsuario(UserCreationForm):
    class Meta:
        fields = ('first_name', 'last_name', 'email', 'username', 'password1', 'password2')

我对django没有多少工作，事实是错误并没有真正告诉我可能出现的问题。

Environment:


Request Method: GET
Request URL: http://127.0.0.1:8000/usuarios/registro/

Traceback:
File "C:\Python27\lib\site-packages\django\core\handlers\base.py" in get_response
  114.                     response = wrapped_callback(request, *callback_args, **callback_kwargs)

Exception Type: TypeError at /usuarios/registro/
Exception Value: 'str' object is not callable

您在网址调度中错误地命名了您的视图：

from usuarios.views import Registro

urlpatterns = patterns('',
    # ...

    url(r'^registro/$', 'Registro', name='registro'),

这里'Registro'不是Django可以导入的名称（它不是完整的模块路径），也没有指定要导入的前缀（patterns()的第一个参数是空字符串{ {1}}）。

您应该提供实际的视图对象（您已在此处导入），或者为其提供完整模块路径的名称。

所以选择以下之一：

''

或

from usuarios.views import Registro

urlpatterns = patterns('',
    # ...

    url(r'^registro/$', Registro, name='registro'),

第一个选项将实际的视图函数传递给寄存器（因为你已经导入了它，所以它可以工作）。

除视图名称外，第二个选项提供模块的完整路径; Django现在可以导入它（它在字符串中查找urlpatterns = patterns('', # ... url(r'^registro/$', 'usuarios.views.Registro', name='registro'),以确定是否可以导入某些内容。）

'str'对象不可调用
