ruby-on-rails - 从数据库中选择的 RoR 映射数组

Question

我选择

m_repeats = Event.all

然后我需要更改每个元素中的时间段（它是日期字段）。我需要为当前（日期）设置年份和月份

我尝试这样做：

m_repeats.map{ |elem| elem.schedule.year = date.year, elem.schedule.month = date.month } 

但我得到错误：

undefined method `month=' for Wed, 03 Apr 2013:Date

我如何通过地图更改它们？

Answer 1

There is no 'month=' method for Date class. I guess this will work,

m_repeats.map{ |elem| elem.schedule = Date.new(Date.today.year, Date.today.month, elem.schedule.day)}
