ruby - 获取季度的开始/结束日期

Question

我如何计算日期的 quarter begin/end dates ？例如，如果我给出方法 "2012-10-11" 我想返回:{ :begin_date => '2012-10-01', :end_date => '2012-12 -31'

def quarter_dates(date = Date.today)
  # TODO...
  return {
    :begin_date => begin_date,
    :end_date => end_date
  }
end

Answer 1

ActiveSupport提供 beginning_of_quarter和 end_of_quarter仅此而已:

require 'active_support/core_ext/date/calculations'

def quarter_dates(date = Date.today)
  {
    begin_date: date.beginning_of_quarter,
    end_date: date.end_of_quarter
  }
end
