django - 通过 django FormWizard 传递数据

Question

我正在尝试构建一个 django 表单向导，以允许人们注册事件。我可以完成表单向导并查看 done 方法中的数据。问题是我还需要将 event_id 传递给 did 。如何得到通过表单向导将 event_id 从 URL 转换为 done？简单的例子？

------- urls.py ---------
named_register_forms2 = (
    ('basicdata', SeatsForm),
    ('form2', AnotherForm),
)

urlpatterns = patterns('',
    url(r'^register/(?P<event_id>\d+)/$', register_wizard, name='register_step'),
)

------ forms.py -----------
class SeatsForm(forms.ModelForm):

  class Meta:
    model = MyModel
    fields = [ 'last_name', 'first_name', 'address1', 'address2', 
               'city', 'state', 'zipcode', 'phone_number', 'email']

  def __init__(self, *args, **kwargs):
      super(SeatsForm, self).__init__(*args, **kwargs)

class RegisterWizard(SessionWizardView):
    #storage_name = 'formtools.wizard.storage.session.SessionStorage'
    template_name = 'wizard_form.html'

    def done(self, form_list, **kwargs):
        data = {}
        for form in form_list:
                data.update(form.cleaned_data)
                print data
        # I need event_id right here.  How to get it?
        return render_to_response('done.html', {
            'form_data': [form.cleaned_data for form in form_list],
    })

我认为您必须将其放入表格中并从那里获取。

如果是模型形式，您可以将 instance_dict 参数传递给向导 View 。 instance_dict param 。但是在这种情况下，您将必须实现一个包装 View ，该 View 将使用这些参数准备向导 View 。像这样的事情:

def wrapper_view(request, id):
    #somecode
    seats_instance = SeatsModel.objects.get(id=id)
    another_instance = AnotherModel.objects.get(id=id)
    inst_dict = { '0': seats_instance,
                  '1': another_instance
                }
    return RegisterWizard.as_view(named_register_forms2, instance_dict=inst_dict)(request)

class RegisterWizard(SessionWizardView):
    #storage_name = 'formtools.wizard.storage.session.SessionStorage'
    template_name = 'wizard_form.html'

    def done(self, form_list, **kwargs):
        data = {}
        seatform= form_list[0]
        seatinst = form.save()    
        #save other forms
        ...
        #using seatinst get event id

        return render_to_response('done.html', {
            'form_data': [form.cleaned_data for form in form_list],
             })
