它在我的本地计算机上运行正常但在Heroku的rails_admin中使用Puma Web服务器时出现以下错误。
这是我如何使用enumerize
enumerize :date_type, in: { last_date: 0, begin_date: 1 },
default: :last_date, predicates: { prefix: true, only: :last_date },
i18n_scope: 'date_type'
它出现以下错误，我已经从我的rollbar中粘贴了错误。刷新页面几次以某种方式工作，它显示模型页面就好了。但大部分时间都会出错。此外，使用数组而不是哈希来定义date_type，即in: [:last_date, :begin_date]＆amp;在rails_admin的列表视图中没有date_type似乎解决了这个问题，否则我收到以下错误。
NoMethodError: undefined method `empty?' for 0:Fixnum

根据用法部分中的enumerize README，in:的参数应该是一个数组而不是您提供的哈希值。所以，改变：
in: { last_date: 0, begin_date: 1 }
为：
in: [:last_date, :begin_date]
