python - Django:在表单属性 MultipleChoiceField 上设置选项

Question

我有以下 Django 形式:

class SpecifyColumnsForm(forms.Form):
    columns = forms.MultipleChoiceField(required=False,
    widget=forms.CheckboxSelectMultiple)

现在，我想从 views.py 中为这个 MultipleChoiceField 指定选项。我该怎么做？

我试过以下方法，但没有用:

        columns_form = SpecifyColumnsForm(request.POST)
        columns_form.choices = (('somestuff', 'spam'),
                                ('otherstuff', 'eggs'),
                                ('banana', 'bar'))

谢谢!

Answer 1

documentation本身声明

class MultipleChoiceField(**kwargs)¶

[...]

Takes one extra required argument, choices, as for ChoiceField.

所以你所要做的就是

cool_choices = (('somestuff', 'spam'),
                ('otherstuff', 'eggs'),
                ('banana', 'bar'))

class SpecifyColumnsForm(forms.Form):
    columns = forms.MultipleChoiceField(
        required=False,
        widget=forms.CheckboxSelectMultiple,
        choices=cool_choices)
