如何使用 Bootstrap 在 Django 中自定义复选框和单选框？

我正在尝试使用 bootstrap 类自定义 Django 中的复选框和单选按钮。然而，这并没有奏效。

我已经尝试在 forms.py 中插入引导类widgets and attrs: custom-control custom-radio custom-control-inline custom-control-input custom-control-label

My code:

模型.py

Y = 1
N = 2

YN = (
    (Y, 'yes'),
    (N, 'no'),)

class Prop(models.Model):
    yesorno = models.IntegerField(choices=YN, default=Y, verbose_name='Label...')

forms.py

class PropForm(forms.ModelForm):
    class Meta:
        model = Prop
        exclude = ()
        widgets={
            'yesorno': forms.RadioSelect(
                attrs={
                    'class':'custom-control-input custom-control-label',
                }
            ),
        }

模板.html

<form action="" method="POST">
     {% csrf_token %}
     <div class="custom-control custom-radio custom-control-inline">
       {{ form.yesorno.label_tag }} {{ form.yesorno }}
     </div>
</form>

HTML 呈现

<div class="custom-control custom-radio custom-control-inline">
 <label for="id_yesorno_0">Label...?</label>
 <ul id="id_yesorno" class="custom-control-input custom-control-label">
   <li>
    <label for="id_yesorno_0"><input type="radio" name="yesorno" value="1" class="custom-control-input custom-control-label" required="" id="id_yesorno_0">yes</label>
   </li>
   <li>
    <label for="id_yesorno_1"><input type="radio" name="yesorno" value="2" class="custom-control-input custom-control-label" required="" id="id_yesorno_1" checked="">no</label>
   </li>
 </ul>
</div>

我想使用自定义引导样式（https://getbootstrap.com/docs/4.3/components/forms/#radios).

我需要渲染一个 HTML，如下面的代码所示：

<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline1" name="customRadioInline1" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline1">Toggle this custom radio</label>
</div>
<div class="custom-control custom-radio custom-control-inline">
  <input type="radio" id="customRadioInline2" name="customRadioInline1" class="custom-control-input">
  <label class="custom-control-label" for="customRadioInline2">Or toggle this other custom radio</label>
</div>

Expected result:

到目前为止我最好的解决方案。 我必须手动渲染。

模板.html

<!-- radio -->
<div class="form-group">
    {{ form.field_name.label_tag }}
    {% for pk, choice in form.field_name.field.widget.choices %}
    <div class="custom-control custom-radio custom-control-inline">
        <input id="id_{{form.field_name.name}}_{{ forloop.counter0 }}" name="{{form.field_name.name}}" type="{{form.field_name.field.widget.input_type}}" value="{{pk}}" class="custom-control-input"
         {% ifequal form.field_name.data pk.0 %}
           checked="checked"
         {% endifequal %}/>
        <label for="id_{{form.field_name.name}}_{{ forloop.counter0 }}" class="custom-control-label">{{ choice }}</label>
    </div>
    {% endfor %}

<!-- checkbox -->
