为什么我的 Rails FormHelper (Formtastic) 无法正确显示布尔值？
我正在使用 Formtastic 并且有一个简单的布尔字段。在我看来，我把
<%= f.input :active, :label => "Enabled?", :as => :select, :include_blank => false, :collection => [ ["Yes", true], ["No", false] ] %><br />
它保存到数据库就好了。但是当它加载时，它总是显示第一个值（“是”）。
我缺少什么？当该字段为 false 时，它应默认为“否”。
感谢您的任何提示。

当我把[“否”，假]放在第一位时，它起作用了！
<%= f.input :active, :label => "Enabled?", :as => :select, :include_blank => false, :collection => [ ["No", false], ["Yes", true] ] %>
为什么这很重要？
I am using Formtastic and I have a simple boolean field. In my view, I have
<%= f.input :active, :label => "Enabled?", :as => :select, :include_blank => false, :collection => [ ["Yes", true], ["No", false] ] %><br />
It saves to the database just fine. But when it loads, it always shows the first value ("Yes").
What am I missing? It should default to "No" when the field is false.
Thanks for any tips.
EDIT
When I put the ["No", false] first, it works!
<%= f.input :active, :label => "Enabled?", :as => :select, :include_blank => false, :collection => [ ["No", false], ["Yes", true] ] %>
Why would that matter?????

这是关于主题
https://rails.lighthouseapp.com/projects/8994/tickets/5702-options_for_select-do-not-select-boolean-values- Correctly
并在rails >= v3.0.3 中修复
Here is a submitted bug/patch on the topic
https://rails.lighthouseapp.com/projects/8994/tickets/5702-options_for_select-do-not-select-boolean-values-correctly
and it is fixed in rails >= v3.0.3
如果删除
:include_blank => 会发生什么？假的？是否选择了第一个选项（空白）？如果是，该属性的值是否可以为nil而不是false？What happens if you remove the
:include_blank => false? Is the first option (blank) selected? If so, could the value for the attribute beniland notfalse?
