在Django Form中获取当前用户[重复]

Question

可能重复：
get request data in Django form

我的访客模型的一部分：

class Guest(models.Model):
    event = models.ForeignKey(Event, related_name='guests')
    user = models.ForeignKey(User, unique=True, related_name='guests')
    ...

获取客人回复的表单：

class RSVPForm(forms.Form):
    attending_d= forms.ChoiceField(choices=VISIBLE_ATTENDING_CHOICES, initial='yes', widget=forms.RadioSelect)
    attending_b = forms.ChoiceField(choices=VISIBLE_ATTENDING_CHOICES, initial='yes', widget=forms.RadioSelect)
    number_of_guests = forms.IntegerField(initial=0)
    comment = forms.CharField(max_length=255, required=False, widget=forms.Textarea)

    ....    

    def save(self):
        guest = self.guest_class.objects.get(user=1)
        guest.attending_status_d = self.cleaned_data['attending_d']
        guest.attending_status_b = self.cleaned_data['attending_b']
        guest.number_of_guests = self.cleaned_data['number_of_guests']
        guest.comment = self.cleaned_data['comment']
        guest.save()
        return guest

问题在于保存方法。如何将访客与当前登录的用户关联？

guest = self.Guest.objects.get(user=1)

我需要的是当前登录用户的 ID，而不是 user=1。

谢谢！

Answer 1

我找到了方法:)

1. 在表单上写一个__init__ 方法：

   def __init__(self, user, *args, **kwargs):
       self.user = user
       super(RSVPForm, self).__init__(*args, **kwargs)
   

2. 更改视图函数，并将 request.user 传递给表单

   def event_view(request, slug, model_class=Event, form_class=RSVPForm,
                                   template_name='rsvp/event_view.html'):
       event = get_object_or_404(model_class, slug=slug)
   
       if request.POST:
           form = form_class(request.user, request.POST)
   
       if form.is_valid():
           guest = form.save()
           return HttpResponseRedirect(reverse('rsvp_event_thanks',
                       kwargs={'slug': slug, 'guest_id': guest.id}))
       else:
           form = form_class(request.user)
   
       return render_to_response(template_name, {
           'event': event,
           'form': form,
       }, context_instance=RequestContext(request))
   

3. save() 方法的行现在看起来像这样：

   guest = self.guest_class.objects.get(user=self.user)
