Rails form_for radio_button"不能为空"

Question

我有以下代码:

<% form_for(@libation) do |f| %>
  <%= f.radio_button :carbonated, true  %> <%= f.label :carbonated, "Yes" %>
  <%= f.radio_button :carbonated, false %> <%= f.label :carbonated,  "No" %>
<% end %>

carbonated数据库中的列是类型tinyint.
当上面运行并且我点击时,No我得到一个大红框告诉我:

1 error prohibited this libation from being saved
  There were problems with the following fields:
  * Carbonated can't be blank

有任何想法吗？

Answer 1

我对布尔值的验证有困难,所以我学会了验证你需要做的存在:

validates_inclusion_of :carbonated, :in => [true, false]
