有条件地显示和隐藏表单域并设置字段值

Question

我的Django中有一个表单,看起来像这样:

class PersonnelForm(forms.Form):
    """
    Form for creating a new personnel.
    """
    username = forms.RegexField(
        required=True, max_length=30, label=_("Name")
    )
    is_manager = forms.BooleanField(
        required=True, label=_("Is Manager")
    )

我在我的网站的两个地方使用此表单.其中一个地方,我想显示表单及其除字段以外的所有is_manager字段,但我想将此字段的默认值设置为True.在另一个地方,我想显示表单及其所有字段,包括is_manager字段,我希望它的默认值为False.

我怎么能做到这一点？似乎是一件微不足道的事情,但我无法弄清楚.

谢谢.

您可以使用表单的__init__方法来隐藏(或删除)字段,即

class PersonnelForm(forms.Form):
    """
    Form for creating a new personnel.
    """
    username = forms.RegexField(
        required=True, max_length=30, label=_("Name")
    )
    is_manager = forms.BooleanField(
        required=True, label=_("Is Manager")
    )

    def __init__(self, *args, **kwargs):
        delete_some_field = kwargs.get('delete_some_field', False)
        if 'delete_some_field' in kwargs:
            del kwargs['delete_some_field']
        super(PersonnelForm, self).__init__(*args, **kwargs)
        if delete_some_field:
            del self.fields['is_manager']
            # or
            self.fields['is_manager'].widget = something_else

#views.py
form = PersonnelForm(...., delete_some_field=True)
