将params [:date]转换为Date的禅方式？

Question

将params[:date]字段转换为Date对象的最优雅方法是什么？

"date"=>{"day"=>"13", "year"=>"2012", "month"=>"4"}

目前,我在以下代码中有以下代码controller:

@date = Date.current
if params[:date]
  yy = mm = dd = 0
  yy = params[:date][:year].to_i  if params[:date][:year]
  mm = params[:date][:month].to_i if params[:date][:month]
  dd = params[:date][:day].to_i   if params[:date][:day]
  @date = Date::civil(yy, mm, dd) if Date::valid_date?(yy, mm, dd)
end

并且里面view的form_tag:

<%= select_date(@date, :order => [:year, :month, :day], :prefix => 'date') %>

Answer 1

它将返回有效的日期或时间对象.试试:

@date = Date.parse("#{params[:date]['day']}-#{params[:date]['month']}-#{params[:date]['year']}") if params[:date]
OR
@date = Time.parse("#{params[:date]['day']}-#{params[:date]['month']}-#{params[:date]['year']}") if params[:date]

@date ||= Date.current
