Django - 如何将模型的选择显示为复选框

Question

我关注了this但我仍然无法在表单上将选项显示为复选框。

模型.py

class Car(models.Model):
    TYPE_CHOICES = (
       ('s', 'small'),
       ('m', 'medium'),
       ('b', 'big'),
     )
     type = models.CharField(max_length=1, choices=TYPE_CHOICES)

表单.py

from django import forms
from django.forms.widgets import CheckboxSelectMultiple

from cars.models import Car

class AddCar(forms.ModelForm):
    class Meta:
        model = Car
        type = forms.MultipleChoiceField(choices=Car.TYPE_CHOICES, widget=forms.CheckboxSelectMultiple())

Answer 1

您需要使用 forms.RadioSelect() 而不是 forms.CheckboxSelectMultiple() 因为它是单值。

要覆盖 ModelForm 的小部件，check the doc

class AddCar(forms.ModelForm):
    class Meta:
        model = Car
        widgets = {'type': forms.RadioSelect}

或者如您的问题所示，type 行应该位于 class Meta 行上方，位于 AddCar

class AddCar(forms.ModelForm):
    type = forms.ChoiceField(choices=Car.SCENERY_CHOICES, widget=forms.RadioSelect)

    class Meta:
        model = Car
