布尔值不在Heroku上更新，但在本地工作

Question

我的申请包含Items。它们具有status属性，它是一个布尔值。我通过rails g migration AddStatusToItems status:boolean将其添加到项目中。要在视图中将项目的状态显示为完成或待处理，我只需执行

<% if status? %>
Complete
<% else %>
Pending
<% end %>

哦是的，我还在控制器中的params哈希中添加了:status。

它可以在本地运行，但在Heroku上，状态才会恢复到待处理状态。这是Heroku上的日志。我怎样才能使这个工作？
