ruby-on-rails - Rails_admin 错误从 0.6.3 升级到 1.4 后实例变量名不允许

Question

错误：`@charged?_registered' 不允许作为实例变量名

将 rails admin 升级到最新版本后，我收到此错误，它之前运行良好。它向我显示了此代码片段中的错误。

scope :charged, -> { where.not(charge_transaction: nil) }

  rails_admin do
    object_label_method do
      :uuid
    end
    list do
      sort_by :campaign
      # filters [:campaign, :uuid]
      field :uuid
      field :campaign do
        searchable [:id, :product_name]
      end
      field :user do
        searchable [:email, :handle, { :orders => :full_name }]
      end
      field :full_name
      field :charged?
      field :shipment_id?
      scopes [nil, :currently_open, :charged, :campaign_funded_not_charged, :label_not_created, :paid_and_shipped]
    end
    configure :created_at do
      show
    end
    configure :updated_at do
      show
    end
  end

  def charged?
    return !self.open?
  end

这是我的控制台输出：

NameError - `@charged?_registered' is not allowed as an instance variable name:

任何想法我如何解决这个问题

由于charged?它是对象的方法而不是属性，因此您可以这样配置它：

field :charged do
  formatted_value do
    bindings[:object].charged?
  end
  label do
    'Charged?'
  end
end
