Question

不使用javascript，是否有更好的方法来记住用户的单选按钮选择？我觉得我有一种非常天真（？）的方式吗？

我怎样才能重新写这个以使它更干？提交时，usersegment parem会在同一页面上返回。

{% if usersegment == "non-paying" %}
<input type="radio" name="usersegment" value="non-paying" checked="yes"/> Non-paying Users <br />
<input type="radio" name="usersegment" value="paying" /> Paying Users <br />
<input type="radio" name="usersegment" value="all" /> All Users<br />
{% endif %}

{% if usersegment == "paying" %}
<input type="radio" name="usersegment" value="non-paying" /> Non-paying Users <br />
<input type="radio" name="usersegment" value="paying" checked="yes"/> Paying Users <br />
<input type="radio" name="usersegment" value="all" /> All Users<br />
{% endif %}

{% if usersegment == "all" or not usersegment %}
<input type="radio" name="usersegment" value="non-paying" checked="yes"/> Non-paying Users <br />
<input type="radio" name="usersegment" value="paying" /> Paying Users <br />
<input type="radio" name="usersegment" value="all" checked="yes"/> All Users<br />
{% endif %}

这个怎么样：

<input type="radio" name="usersegment" value="non-paying" {% if usersegment == "non-paying" %}checked="checked"{% endif %}/> Non-paying Users <br />
<input type="radio" name="usersegment" value="paying" {% if usersegment == "paying" %}checked="checked"{% endif %}/> Paying Users <br />
<input type="radio" name="usersegment" value="all" {% if usersegment == "all" or not usersegment %}checked="checked"{% endif %}/> All Users<br />

另外，请考虑使用django forms。像那些琐碎的问题在那里以非常优雅的方式解决，你甚至不需要考虑它。
