django 中写注册页面时，运行出现的问题？

[tooweakchen]

错误如下：
'dict' object is not callable
Request Method: POST
Request URL: http://127.0.0.1:8000/main/register/
Django Version: 1.8.6
Exception Type: TypeError
Exception Value:

'dict' object is not callable

而我在 view 里面写的注册代码是：
def register_page(request):
if request.method=='POST':
form =RegistrationForm(request.POST)
if form.is_valid():
new_user=User.objects.create_user(
user=form.cleaned_data['user'],
email=form.cleaned_data['email'],
password=form.cleaned_data['password'],

)
        return HttpResponseRedirect('/main/register/success/')
else:
    form=RegistrationForm()
    #return render(request,'registration/resgister.html',)
    #form=RegistrationForm()
variables=RequestContext(request,{'form':form})
return render_to_response('registration/resgister.html',variables)


为什么当我把信息填好后，点击注册的时候，出现了那个问题啊？
