Rails f.check_box设置选中/未选中的值 [英] Rails f.check_box set checked/unchecked values

问题描述

所以我在rails中有一个复选框的窗体助手;
当选中或取消选中时，我想要该复选框的值为thatvalue或thisvalue;
我没有找到任何地方如何设置这个与

  f.check_box：field 
  

我发现了这样的东西。

 <％= form.check_box：field，{}，thisvalue，thatvalue％> 
  

但它不工作，因为我还在标签中设置了class和：style具有类似

 <％= form.check_box：field，{}，thisvalue，thatvalue，：class => checkbox，：style => display：none; ％> 
  

错误，并告诉我错误的参数数量（5为4）

所以现在我必须在我的控制器黑客，并设置我的字段取决于我的复选框是0还是1 ...这是很糟糕。

任何想法？

解决方案

ok nevermind，我误解了options p>

答案只是

 <％= f.check_box：field ，{：class => myclass，：style => mystyle}，checked-value，unchecked-value％> 
  

它完美地工作：）

so I got a form helper in rails with a checkbox; I want that checkbox to have values as "thatvalue" or "thisvalue" when checked or unchecked; I haven't found anywhere how to set this up with

f.check_box :field

I found something like that

<%= form.check_box :field, {}, "thisvalue", "thatvalue"  %>

but it doesn't work, because I also set :class and :style inside my tag, so having something like

<%= form.check_box :field, {}, "thisvalue", "thatvalue", :class => "checkbox", :style => "display:none;" %>

errors and tells me wrong number of arguments (5 for 4)

so right now I have to "hack" it in my controller, and set my field depending on if my checkbox is 0 or 1... which is pretty bad.

any idea?

解决方案

ok nevermind, I misunderstood the "options" field...

the answer is simply

<%= f.check_box :field, {:class => "myclass", :style => "mystyle"}, "checked-value", "unchecked-value" %>

and it works perfectly :)
