Rails admin - 在导出部分自定义关联的差异值

Question

我有两个模型。 JobPosition 和 LineManager 。一个直线经理可以有不同的职位，一个职位有一个直线经理。在 rails admin 中，我想导出代表直线经理属性的不同列，包括：名称、部门等！

config.model 'JobPosition' do
  export do
    field :line_manager, :string do
      export_value do
        value.name if value #value is an instance of Teacher
      end
    end
    field :line_manager, :string do
      export_value do
        value.title if value #value is an instance of Teacher
      end
    end
    field :line_manager, :string do
      export_value do
        value.department if value #value is an instance of Teacher
      end
    end
    field :line_manager, :string do
      export_value do
        value.description if value #value is an instance of Teacher
      end
    end
    field :line_manager, :string do
      export_value do
        value.job_level if value #value is an instance of Teacher
      end
    end
  end
end

但它只应用第一个而不应用其他的。我还想更改 header 列。我尝试添加这样的标签：

field :line_manager, :string do
      export_value do
        lable "line manager name"
        value.name if value #value is an instance of Teacher
      end
end

但我想这是不正确的。你有什么想法吗？

Answer 1

试试 formatted_value

config.model 'JobPosition' do
    configure :line_manager, :string do
      formatted_value do
        value.job_level if value #value is an instance of Teacher
      end
    end
end

Answer 2

一个可能的解决方案是像这个例子一样导出虚拟字段

field :line_manager_departmant, :string do
  label "Line Manager Department"
  pretty_value do
    bindings[:object].line_manager.department
  end
end

field :line_manager_description, :string do
  label "Line Manager Description"
  pretty_value do
    bindings[:object].line_manager.description
  end
end
