Question

所以我正在处理一个现有的应用程序，出于某些原因，我能够让它在我的本地环境中工作和镜像，但是当我尝试在heroku上迁移时，我得到以下错误，有任何想法吗？

错误：

迁移文件：

class CreateReleasedInventoryStatus < ActiveRecord::Migration

  def change
    create_enum("eh_released_inventory_status", ["rejected", "pending", "allocated", "released", "transferred"])
  end
end

我认为您使用的是power_enum，并且已在您development的{{1}}组中声明。因此，Rails不会在Gemfile环境中加载它并导致此错误。

因此，请检查您的production。

未定义的方法`create_enum＆＃39;在生产中迁移时出错
