我希望我错了,但在我看来,没有help_textManyToManyField 的唯一方法是为表单编写一个__init__方法并覆盖self.fields[fieldname].help_text。这真的是唯一的方法吗?我更喜欢使用CheckboxSelectMultple小部件,所以我真的必须__init__为任何使用ManyToManyField?
class ManyToManyField(RelatedField, Field):
description = _("Many-to-many relationship")
def __init__(self, to, **kwargs):
#some other stuff
msg = _('Hold down "Control", or "Command" on a Mac, to select more than one.')
self.help_text = string_concat(self.help_text, ' ', msg)
