标题没有显示使用to_xls

Question

我正在使用gem to_xls，从activerecords生成xls文件非常棒。但由于某些原因，我无法显示标题。

这是控制器：

  format.xls {
    send_data @tickets.to_xls(
      :columns => [:created_at, :title, {:category => :title}, {:group => :name}, {:location => :name}, :starts, :target, {:requestor => :full_name}, :percent_complete, :recurring, :cost, :spent, :task_level],
      :headers => [:created, :name, :category, :group, :location, :start_date, :target_date, :requestor, :percent_complete, :recurring, :cost, :spent, :task_level]
    )
  }

Answer 1

to_xls插件不显示带有关联模型的标头，因为它无法理解属性名称。

您可以尝试为标题而不是属性提供字符串：

format.xls {
    send_data @tickets.to_xls(
      :columns => [:created_at, :title, {:category => :title}, {:group => :name}, {:location => :name}, :starts, :target, {:requestor => :full_name}, :percent_complete, :recurring, :cost, :spent, :task_level],
      :headers => ["created", "name", "category", "group", "location", "start_date", "target_date", "requestor", "percent_complete", "recurring", "cost", "spent", "task_level"]
    )
}
