单轨按钮的标签形式 [英] Labels for radio buttons in rails form

问题描述

我的问题类似于这一个
但对于一个Rails应用程序。

我有一个单选按钮的表单，并希望将标签与它们关联。 标签表单助手仅将表单字段作为参数，但在这种情况下，对于单个表单字段，我有多个单选按钮。我看到要做到这一点的唯一方法是手动创建一个标签，硬编码自动为单选按钮生成的标识。有人知道更好的方法吗？例如：

 <％form_for（@message）do | f | ％GT; 
<％= label：contactmethod％> 
<％= f.radio_button：contactmethod，'email'，：checked => true％>电子邮件
<％= f.radio_button：contactmethod，'sms'％> SMS 
<％end％> 
  

这会产生类似于：

 < label for =message_contactmethod> Contactmethod< / label> 
< input checked =checkedid =message_contactmethod_emailname =message [contactmethod]value =emailtype =radio>电子邮件
< input id =message_contactmethod_smsname =message [contactmethod]value =smstype =radio> SMS 
  

我想要的：

 < input checked =checkedid =message_contactmethod_emailname =message [contactmethod]value =emailtype =radio>< label for =message_contactmethod_email> ;电子邮件与LT; /标签> 
< input id =message_contactmethod_smsname =message [contactmethod]value =smstype =radio> < label for =message_contactmethod_sms> SMS< / label> 
  

解决方案

 < ％form_for（@message）do | f | ％GT; 
<％= f.radio_button：contactmethod，'email'，：checked => true％> 
<％= label：contactmethod_email，'电子邮件'％> 
<％= f.radio_button：contactmethod，'sms'％> 
<％= label：contactmethod_sms，'SMS'％> 
<％end％> 
  

My question is similar to this one but for a Rails app.

I have a form with some radio buttons, and would like to associate labels with them. The label form helper only takes a form field as a parameter, but in this case I have multiple radio buttons for a single form field. The only way I see to do it is to manually create a label, hard coding the ID that is auto generated for the radio button. Does anyone know of a better way to do it?

For example:

<% form_for(@message) do |f| %>
    <%= label :contactmethod %>
    <%= f.radio_button :contactmethod, 'email', :checked => true %> Email
    <%= f.radio_button :contactmethod, 'sms' %> SMS
<% end %>

This generates something like:

<label for="message_contactmethod">Contactmethod</label>
<input checked="checked" id="message_contactmethod_email" name="message[contactmethod]" value="email" type="radio"> Email
<input id="message_contactmethod_sms" name="message[contactmethod]" value="sms" type="radio"> SMS

What I want:

<input checked="checked" id="message_contactmethod_email" name="message[contactmethod]" value="email" type="radio"><label for="message_contactmethod_email">Email</label>
<input id="message_contactmethod_sms" name="message[contactmethod]" value="sms" type="radio"> <label for="message_contactmethod_sms">SMS</label>

解决方案

<% form_for(@message) do |f| %>
  <%= f.radio_button :contactmethod, 'email', :checked => true %> 
  <%= label :contactmethod_email, 'Email' %>
  <%= f.radio_button :contactmethod, 'sms' %>
  <%= label :contactmethod_sms, 'SMS' %>
<% end %>
