我有这样的形式:
class TitlePropose(forms.Form):
title = forms.CharField(max_length=128)
code= forms.CharField(max_length=32)
def __init__(self, contest, *args, **kwargs):
super(TitlePropose, self).__init__(*args, **kwargs)
self.helper = FormHelper()
self.helper.form_id = self.__class__.__name__.lower()
self.helper.form_action = ''
self.helper.layout = Layout(,
Field('title'),
Field('code'),
)
def clean_title(self):
if OtherModel.objects.filter(contest=contest, title=self.cleaned_data['title']).count() > 0:
raise forms.ValidationError("Title unavailable")
else:
return self.cleaned_data['title']
我尝试从clean_title方法访问变量“contest”,但没有任何成功。我在表单类contructor中传递了这个变量:
#contest is just some object
new_title_form = TitlePropose(contest=contest.uuid)
任何建议,如何在clean_title中获取“竞赛”?
答案 0 :(得分:2)
这是标准的Python类。如果要存储对象以便其他方法可以访问它,可以通过将其添加到self
来使其成为实例属性。
def __init__(self, *args, **kwargs):
self.contest = kwargs.pop('contest')
super(TitlePropose, self).__init__(*args, **kwargs)
def clean_title(self):
if OtherModel.objects.filter(contest=self.contest, ...
