我的表格如下:
class ConsentFormTpl(forms.Form):
title = forms.CharField()
message = forms.CharField(widget=EditorWidget,label='Description')
acknowledge = forms.BooleanField(label="Require acknowledgement?")
deadline = forms.DateField(widget=CalendarTimeWidget,label="Acknowledge By")
start_time = forms.DateTimeField(widget=CalendarTimeWidget)
end_time = forms.DateTimeField(widget=CalendarTimeWidget)
availClass = forms.ModelChoiceField(queryset=SchoolClass.objects.all(),empty_label="Select a class",label='Class')
consent = forms.BooleanField()
students = forms.ModelMultipleChoiceField(label="",\
queryset=User.objects.filter(groups__name='Students').extra(select={'user_name':"first_name || ' ' || last_name"}), \
widget=FilteredSelectMultiple("Students",is_stacked=False))
where = forms.CharField()
form_name = forms.CharField(label='Save as:')
def __init__(self,data=None,draft=False):
super(ConsentFormTpl,self).__init__(data)
self.draft = draft
self.acknowledge.required = False
self.deadline.required = False
self.start_time.required = False
self.end_time.required = False
self.availClass.required = False
self.consent.required = False
self.where.required = False
if draft:
self.title.required = False
self.message.required = False
self.students.required = False
self.form_name.required = True
else:
self.form_name.required = False
根据草稿的值,我想更改某些字段的属性(必需),这是init方法中的内容。
但是我遇到了以下消息:
'ConsentFormTpl' object has no attribute 'acknowledge'
任何人都知道为什么?
答案 0 :(得分:18)
这些字段在表单实例上不可用作属性。它们在self.fields
中可用作字典元素。所以:
self.fields['acknowledge'].required = False
等等。
