获取当前用户

Question

可能重复：
get request data in Django form

有我的客户模型的一部分：

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

形式来从客户的反应：

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。我如何将访客与当前登录的用户相关联？

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

而不是user=1我需要有当前登录的用户的ID。

谢谢！

Answer 1

我找到了方法:)

1. 写在表格上一个__init__方法：

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

2. 更改视图功能，并通过request.user的形式

   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)
