我有一个简单的模型如下：

RATING_CHOICES = zip(range(1, 6), range(1, 6))
class Rating(models.Model):

    value = models.IntegerField(choices=RATING_CHOICES)
    additional_note = models.TextField(null=True, blank=True)
    from_user = models.ForeignKey(User, related_name='from_user')
    to_user = models.ForeignKey(User, related_name='to_user')
    shared_object = models.ForeignKey(ObjectDetail, null=True, blank=True)
    dtobject = models.DateTimeField(auto_now_add=True)

从上面的模型中，我生成了一个模型表单，在我的 forms.py 中如下：

class RatingForm(ModelForm):

     class Meta:
          model = Rating
          exclude = ('from_user', 'dtobject',
                     'shared_object')

在我的网址中，我尝试以下操作：

url(r'^rate/(?P<form_type>[\w]+)/(?P<oid>\d+)/(?P<oslug>[\w-]+)/$', 'rating_form', name='rating_form'),

在我看来，以下几点：

def rating_form(form_type = None, oid = None, oslug=None):

    print form_type
    form = RatingForm(data=request.POST or None)

    if request.POST and form.is_valid():
           form.save()
        return HttpResponseRedirect("/")
    else:
        return render(request, "share.html", {'form' : form })

这样做会给我以下错误：

rating_form() 为关键字参数“form_type”获得了多个值

额外细节：

Request Method: GET
Request URL:    http://127.0.0.1:8000/rate/lending/3/random-stuff/
Django Version: 1.4.1
Exception Type: TypeError
Exception Value:    
rating_form() got multiple values for keyword argument 'form_type'
Exception Location: /Library/Python/2.7/site-packages/django/contrib/auth/decorators.py in _wrapped_view, line 20
Python Executable:  /usr/bin/python

我究竟做错了什么？

你的观点的第一个论点应该是request
