Django：如何更改表单中ModelMultipleChiceField的css id？

我的一个表单使用modelmultipechoicefield，它在html上显示一个复选框列表

class CreateProfileForm(forms.Form):
    first_name = forms.CharField(label='First Name', max_length=50)
    last_name = forms.CharField(label='Last Name', max_length=50)
    topics = forms.ModelMultipleChoiceField(label='Assign Topic(s)', 
            widget=CheckboxSelectMultiple(),
            queryset=None)

    def __init__(self, *args, **kwargs):
        event = kwargs.pop('event')
        super (CreateProfileForm, self).__init__(*args, **kwargs)
        self.fields['topics'].queryset = Topic.objects.filter(event=event)

HTML输出

<div id="div_topics">
    <label class="fields">
        <strong><label for="id_topics_0">Assign Topic(s)</label></strong>
    </label>
    <ul>
<li><label for="id_topics_0"><div class="checker" id="uniform-id_topics_0"><span><input type="checkbox" name="topics" value="3" id="id_topics_0" style="opacity: 0; "></span></div> Size</label></li>
<li><label for="id_topics_1"><div class="checker" id="uniform-id_topics_1"><span><input type="checkbox" name="topics" value="2" id="id_topics_1" style="opacity: 0; "></span></div> Flavour</label></li>
<li><label for="id_topics_2"><div class="checker" id="uniform-id_topics_2"><span><input type="checkbox" name="topics" value="1" id="id_topics_2" style="opacity: 0; "></span></div> Citrus</label></li>
</ul>
</div>

如何更改

输入类型

元素的

id

的值？或者基本上将

id\u主题\u 0

等更改为其他内容？

您可以添加auto\u id选项以形成初始方法。但它将更改此表单的所有ID：

您可以添加自动识别选项以形成初始方法。但它将更改此表单的所有ID： 试试这个

def __init__(self, *args, **kwargs):
    event = kwargs.pop('event')
    super (CreateProfileForm, self).__init__(*args, **kwargs)
    self.fields['topics'].queryset = Topic.objects.filter(event=event)
    self.fields['topics'].widget.attrs['class'] = "new_topics_class"

试试这个

def __init__(self, *args, **kwargs):
    event = kwargs.pop('event')
    super (CreateProfileForm, self).__init__(*args, **kwargs)
    self.fields['topics'].queryset = Topic.objects.filter(event=event)
    self.fields['topics'].widget.attrs['class'] = "new_topics_class"
