在Django中为单选按钮设置ID [英] Setting ID for Radio buttons in Django

问题描述

Django 1.4允许 radio select

It is great that Django 1.4 allows fine graining of radio select

{% for radio in form.important_client reversed%}
      {{radio.tag}}<label for="????">{{radio.choice_label}}</label>
{% endfor %}

但由于某种奇怪的原因，使用此方法时，< input> 没有ID。因此，我无法相应地设置< label for ='ID'/> 。

but for some odd reason when using this methodology, the <input> have no IDs. And hence I can't set the <label for='ID' /> accordingly. That causes big issues in my CSS.

是否仍然有设置ID的设置？

Is there anyway to get the IDs set nonetheless?

推荐答案

在调试RadioSelect渲染时，我不知道如何优雅地使用radio标签和标签。因此，这是我为您解决问题的尝试：

While debuging a RadioSelect rendering, I got no idea of using radio tag and label elegantly. So here is my attempt to solve your problem:

{% for radio in form.important_client reversed %}
    <input name="{{ radio.name }}" type="radio" id="radio_{{ radio.index }}" value={{ radio.choice_value }}>
    <label for="radio_{{ radio.index }}">{{ radio.choice_label }}</label>
{% endfor %}

而不是 radio.index 属性（未记录），可以使用 forloop.counter 。

Instead of radio.index property, which is not documented, you can use forloop.counter.

只需输入案例中，我附上了调试窗口的屏幕截图，其中显示了 radio 上下文的示例（图中的 form_of_field 变量）：

Just in case I attach a screenshot of debug window, where example of radio context is shown (form_of_field variable on a figure):
