django choiceField与CheckboxSelectMultiple：默认情况下全部选中？ [英] django choiceField with CheckboxSelectMultiple: all selected by default?

问题描述

我正在将ChoiceField与CheckboxSelectMultiple小部件一起使用。
是否可以将所有复选框默认呈现为选中状态？
谢谢！

I'm using a choiceField with the CheckboxSelectMultiple widget. Is it possible to render all checkboxes as checked by default? Thanks!

推荐答案

只需从字段的选择中设置初始值，就像这样：

Just set the initial values from the field's choices, like this:

MY_CHOICES = (
    ("some", "Some choice"),
    ("another", "Another choice"),
    ("best", "Best choice")
)

...

multiple_choice = forms.MultipleChoiceField(
    label=u"Select multiple", 
    choices=MY_CHOICES, 
    widget=forms.widgets.CheckboxSelectMultiple, 
    initial=(c[0] for c in MY_CHOICES)
)
