通过django FormWizard传递数据

问题描述

我正在尝试建立一个django表单向导，让人们注册一个
事件。我可以通过表单向导查看 done 方法中的数据。
问题是我还需要 event_id 传入完成。如何从url通过表单向导获取
event_id 到完成？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 = {} 
 form_list中的表单：
 data.update（form.cleaned_data）
打印数据
＃我需要event_id就在这里。如何得到它？ 
返回render_to_response（'done.html'，{
'form_data'：form_list中的表单的form.cleaned_data]，
}）
  / pre> 
 
解决方案
我想你必须把它放在窗体中，才能从那里得到。
 
 
 
如果其模型表单可以将 instance_dict  param传递给向导视图。 。但是在这种情况下，您将必须实现一个包装器视图，它将使用这些参数来准备向导视图。这样的东西：
  def wrapper_view（request，id）：
 #somecode 
 seats_instance = SeatsModel。 object.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其他表单
 ... 
 #using seatinst get event id 
 
 return render_to_response（'done。 html'，{
'form_data'：[form.cleaned_data for form in form_list]，
 }）
  
 
I am trying to build a django form wizard to allow people to register for anevent.  I can get through the form wizard and see data in the done method.The problem is that I also need event_id passed into done also.  How do I getevent_id from the url through the form wizard and into done?   Simple example?
------- 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],
    })
 解决方案 
I think you will have to put that in the form and get it from there.
If its model form you can pass instance_dict param to the wizard view. instance_dict param. However in that case you will have to implement a wrapper view that will prepare the wizard view with these params. Something like this:
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],
             })
