Rails 3周显示

Question

如何在轨道中显示一年中剩余的几周？

Answer 1

这里显然没有明确指定格式，但是这样的事情会显示当年剩下的每周的索引：

(Date.today.cweek..52).each { |w| puts w }

有关类似问题，请参阅Looping through weeks of the year in Ruby (Sinatra)

Answer 2

(Date.today.cweek...Date.today.end_of_year.cweek)

修改

(Date.today.cweek...Date.today.end_of_year.cweek).each_slice(2) do |weeks|
  puts weeks.join("-")
end
