DJANGO:改变ModelMultipleChoiceField的字段大小？

Question

我想知道如何改变ModelMultipleChoiceField的大小？我只看过将CharField更改为Textarea的例子......这可能吗？

Models.PY

class FilterForm(forms.Form):
    Person = forms.ModelMultipleChoiceField(required=False, queryset=Person.objects.all(), attrs={'cols': 50, 'rows': 10})

Answer 1

覆盖表单的__init__方法并添加:

self.fields['Person'].widget.attrs['size']='10'

Answer 2

尝试这个：

from django.forms import widgets
class FilterForm(forms.Form):
    Person = forms.ModelMultipleChoiceField(required=False, queryset=Person.objects.all(), widget=widgets.SelectMultiple(attrs={'size': 20}))
