我想在对象列表中显示图标“active.ico”,如果在使用
pretty\u值创建:

list do
  field :created_at do
    pretty_value do
      # result from here will be passed to a view
      if created_at = bindings[:object].try(:created_at)
        if created_at < 1.day
          image_tag("active.ico")  # <img alt="Icon" src="/assets/active.ico" />
        else
          image_tag("passive.ico") # <img alt="Icon" src="/assets/passive.ico" />
        end
      end
    end
  end
end
列出要做的事情
字段:在do处创建
很有价值吗
#此处的结果将传递给视图
如果已创建\u at=bindings[:object]。请尝试(:已创建\u at)
如果在<1.5天时创建
图像标签(“active.ico”)#
其他的
图像标签(“被动式.ico”)#
结束
结束
结束

然后您需要根据需要调整代码示例。例如,将其替换为
image\u标签
list do
  field :created_at do
    pretty_value do
      # result from here will be passed to a view
      if created_at = bindings[:object].try(:created_at)
        if created_at < 1.day
          image_tag("active.ico")  # <img alt="Icon" src="/assets/active.ico" />
        else
          image_tag("passive.ico") # <img alt="Icon" src="/assets/passive.ico" />
        end
      end
    end
  end
