</form>

希望有人能帮我补上缺失的部分

@DanielRoseman，希望你能帮我解决这个问题

【解决方案1】：

这会发生，因为您选择 BooleanField，这意味着特定选择是 0 或 1，并且单选按钮用于从多个选项中选择一个选项，因此您应该尝试使用 forms.ChoiceField 而不是 forms.BooleanField。更多详情请阅读官方django doc

【讨论】：

当我使用forms.ChoiceField时它仍然显示复选框
您是否相应地更改了模板代码example？
我已经这样做了，因为它显示在上面的模板代码中，它仍然呈现复选框

【解决方案2】：

我已经到了某个点，我想它会帮助一些人

模板

{{ formset.management_form }}
<div class="link-formset">
{% for choice in formset %}

<div>
  {{ choice.media }}
 <input type="radio" name="{{choice.featured_image.label}}">{{ choice.featured_image.label }}</
</div>
{% endfor %}
</div>
