以 Django 形式获取当前用户 [英] get current user in Django Form

问题描述

可能的重复:
以Django形式获取请求数据

我的客人模型有一部分:

There's part of my Guest Model:

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

获取客人回复的表格:

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

问题出在保存方法上.如何将访客与当前登录的用户关联?

The problem is in save method. How can I associate guest with the currently logged in user?

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

而不是 user=1 我需要有当前登录用户的 id.

Instead of user=1 I need to have id of the currently logged in user.

谢谢！

推荐答案

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)

更改视图函数，并将 request.user 传递给表单

Change view function, and pass request.user to the form

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))

save() 方法的行现在看起来像这样:

the line of the save() method would look like this now:

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