我是新到詹戈的,我正试图在我的网站上使用django的朋友。
下面是django-others :
>>> from django import forms
>>> class UserForm(forms.Form):
...
... def __init__(self, user=None, *args, **kwargs):
... self.user = user
... super(UserForm, self).__init__(*args, **kwargs)
...
>>> f = UserForm({})
>>> f.is_bound
False
,文件 他说,“绕过空字典会形成一种带有空洞数据的束缚性形式”,但结果为何没有限制(f.is_stric?
谢谢你!
这里发生的情况是,<代码>UserForm利用第一种论点(user)使本国国内国有化,因此它不会将任何东西转至form。 表格。 为了达到预期行为,你可以提出额外的论点:
>>> f = UserForm(None, {})
>>> f.is_bound
True
Your __init__ statement is swallowing the first argument.
Remove user=None from You init statement, 也许将其从kwargs取而代之。
class UserForm(forms.Form):
def __init__(self, *args, **kwargs):
self.user = kwargs.pop( user , None)
super(UserForm, self).__init__(*args, **kwargs)
# now the form is actually receiving your first argument: args[0] == {}
