从上下文创建一组单选按钮 [英] Creating a set of radio buttons from a context

问题描述

我想将列表 y 作为上下文发送到模板.然后，对于 y 中的每个元素 x ，我想在模板中创建一个单选按钮.当我要处理提交的表单时，每个单选按钮应具有等于 x 的 value 属性，并且此单选按钮的标签也应设置为x .

I want to send a list y as a context to a template. Then, for each element x in y, I want to create a radio button in the template. Each radio button should have its value attribute equal to x for when I want to process the submitted form, and the label for this radio button should also be set to x.

在视图中，用于将上下文发送到模板，我有:

In the view, for sending the context to the template, I have:

y = [0] * 10
for i in range(0, 10):
    y[i] = # assign to some value
context = {'y': names}
return render(request, 'mytemplate.html', context)

然后在模板中，我尝试了一些尝试来根据需要显示这些单选按钮，但似乎没有任何效果.例如:

Then in the template, I've tried a few things to try to display these radio buttons as I want, but nothing seems to quite work. For example:

<form>    
    {% for x in y %}
        <label><input type="radio" name="group1" value=x>x</label><br>
    {% endfor %}
</form>

输出一组单选按钮，其标签仅是文本"x"，而不是列表 y 中的值.需要做些什么不同的事情?

outputs a set of radio buttons whose labels are simply the text "x", rather than its value from the list y. What needs to be done differently?

推荐答案

您应使用{{variable_name}}.像这样:

You should use {{ variable_name }}. Like this:

<form>    
{% for x in y %}
    <label><input type="radio" name="group1" value="{{ x }}">{{ x }}</label><br>
{% endfor %}

发生的事情是，您没有使用Django模板的sintax，而只是编写了一个有效的html标签，因此单选按钮中的x是

What happened is that you didn't use Django template sintax and just wrote a valid html label, hence the x in the radio buttons
