这里我添加了一个名为＆＃34;字段的新字段：soaked，：type =＆gt; Boolean＆＃34;，此字段不保存在数据库中，也不显示在视图中。如何解决这个问题请帮帮我。
注意：我也通过了分级参数（浸泡）。
答案 0 :(得分：2)
试试这个：
<%= f.select :active, [['Soaked', true], ['Un-soaked', false]] %>
答案 1 :(得分：0)
浸泡只接受TRUE或FALSE，而您尝试保存"Soaked", "Un-soaked"
<%= f.check_box :soaked %>
您可以使用CHECKBOX。
如果您仍想使用"Soaked"和"Un-soaked"。您可以在您的控制器中进行检查。如果选择Soaked，则保存TRUE其他FALSE
试试这个
<%= f.select :soaked, options_for_select([['Soaked', true], ['Un-soaked', false]]) %>
