前のステップで選択したデータに関連する 1 つのフォームを動的に呼び出すことができます。
しかし、私がdoneメソッドにいるとき、私form_listは変更されていないことがわかります。
これが私がしたことです：
def get_form_list(request, form_list=None):
if form_list is None:
form_list = [ProviderForm, DummyForm, ConsummerForm, DummyForm, \
ServicesDescriptionForm]
return UserServiceWizard.as_view(form_list=form_list)(request)
class UserServiceWizard(SessionWizardView):
instance = None
def __init__(self, **kwargs):
self.form_list = kwargs.pop('form_list')
return super(UserServiceWizard, self).__init__(**kwargs)
def get_form_instance(self, step):
if self.instance is None:
self.instance = UserService()
return self.instance
def get_context_data(self, form, **kwargs):
data = self.get_cleaned_data_for_step(self.get_prev_step(
self.steps.current))
if self.steps.current == '1':
service_name = str(data['provider']).split('Service')[1]
form = class_for_name('th_' + service_name.lower() + '.forms',
service_name + 'ProviderForm')
self.form_list['1'] = form #here my form is correctly change I can see
elif self.steps.current == '3':
service_name = str(data['consummer']).split('Service')[1]
form = class_for_name('th_' + service_name.lower() + '.forms',
service_name + 'ConsummerForm')
self.form_list['3'] = form
context = super(UserServiceWizard, self).get_context_data(form=form,
**kwargs)
return context
def done(self, form_list, **kwargs):
print self.form_list #here form_list contains ProviderForm, DummyForm, ConsummerForm, DummyForm, ServicesDescriptionForm
ステップ 0 で私の form_list は問題ありません:
{u'0': <class 'django_th.forms.wizard.ProviderForm'>,
u'1': <class 'django_th.forms.wizard.DummyForm'>,
u'2': <class 'django_th.forms.wizard.ConsummerForm'>,
u'3': <class 'django_th.forms.wizard.DummyForm'>,
u'4': <class 'django_th.forms.base.ServicesDescriptionForm'>}
ステップ 1 で、私の form_list は問題ありません: 2 番目のフォームが私の予想されるフォームであることがわかります
{u'0': <class 'django_th.forms.wizard.ProviderForm'>,
u'1': <class 'th_rss.forms.RssProviderForm'>,
u'2': <class 'django_th.forms.wizard.ConsummerForm'>,
u'3': <class 'django_th.forms.wizard.DummyForm'>,
u'4': <class 'django_th.forms.base.ServicesDescriptionForm'>}
ステップ 2 で、私の form_list は ko です。ステップ 0 と同じ: 私の 2 番目のフォームは DummyForm に戻ります
{u'0': <class 'django_th.forms.wizard.ProviderForm'>,
u'1': <class 'django_th.forms.wizard.DummyForm'>,
u'2': <class 'django_th.forms.wizard.ConsummerForm'>,
u'3': <class 'django_th.forms.wizard.DummyForm'>,
u'4': <class 'django_th.forms.base.ServicesDescriptionForm'>}
self.form_list を変更しget_context_data、各ステップではなく、ウィザードの最後まで行った変更を保持するにはどうすればよいですか?
ここでの編集 は、ローハンの提案で正常に動作する完全なコードです。
