require "date" require 'action_view/helpers/tag_helper' module ActionView module Helpers # The Date Helper primarily creates select/option tags for different kinds of dates and date elements. All of the select-type methods # share a number of common options that are as follows: # # * :prefix - overwrites the default prefix of "date" used for the select names. So specifying "birthday" would give # birthday[month] instead of date[month] if passed to the select_month method. # * :include_blank - set to true if it should be possible to set an empty date. # * :discard_type - set to true if you want to discard the type part of the select name. If set to true, the select_month # method would use simply "date" (which can be overwritten using :prefix) instead of "date[month]". module DateHelper include ActionView::Helpers::TagHelper DEFAULT_PREFIX = 'date' unless const_defined?('DEFAULT_PREFIX') # Reports the approximate distance in time between two Time or Date objects or integers as seconds. # Set include_seconds to true if you want more detailed approximations when distance < 1 min, 29 secs # Distances are reported base on the following table: # # 0 <-> 29 secs # => less than a minute # 30 secs <-> 1 min, 29 secs # => 1 minute # 1 min, 30 secs <-> 44 mins, 29 secs # => [2..44] minutes # 44 mins, 30 secs <-> 89 mins, 29 secs # => about 1 hour # 89 mins, 29 secs <-> 23 hrs, 59 mins, 29 secs # => about [2..24] hours # 23 hrs, 59 mins, 29 secs <-> 47 hrs, 59 mins, 29 secs # => 1 day # 47 hrs, 59 mins, 29 secs <-> 29 days, 23 hrs, 59 mins, 29 secs # => [2..29] days # 29 days, 23 hrs, 59 mins, 30 secs <-> 59 days, 23 hrs, 59 mins, 29 secs # => about 1 month # 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months # 1 yr <-> 2 yrs minus 1 secs # => about 1 year # 2 yrs <-> max time or date # => over [2..X] years # # With include_seconds = true and the difference < 1 minute 29 seconds # 0-4 secs # => less than 5 seconds # 5-9 secs # => less than 10 seconds # 10-19 secs # => less than 20 seconds # 20-39 secs # => half a minute # 40-59 secs # => less than a minute # 60-89 secs # => 1 minute # # ==== Examples # from_time = Time.now # distance_of_time_in_words(from_time, from_time + 50.minutes) # => about 1 hour # distance_of_time_in_words(from_time, 50.minutes.from_now) # => about 1 hour # distance_of_time_in_words(from_time, from_time + 15.seconds) # => less than a minute # distance_of_time_in_words(from_time, from_time + 15.seconds, true) # => less than 20 seconds # distance_of_time_in_words(from_time, 3.years.from_now) # => over 3 years # distance_of_time_in_words(from_time, from_time + 60.hours) # => about 3 days # distance_of_time_in_words(from_time, from_time + 45.seconds, true) # => less than a minute # distance_of_time_in_words(from_time, from_time - 45.seconds, true) # => less than a minute # distance_of_time_in_words(from_time, 76.seconds.from_now) # => 1 minute # distance_of_time_in_words(from_time, from_time + 1.year + 3.days) # => about 1 year # distance_of_time_in_words(from_time, from_time + 4.years + 15.days + 30.minutes + 5.seconds) # => over 4 years # # to_time = Time.now + 6.years + 19.days # distance_of_time_in_words(from_time, to_time, true) # => over 6 years # distance_of_time_in_words(to_time, from_time, true) # => over 6 years # distance_of_time_in_words(Time.now, Time.now) # => less than a minute # def distance_of_time_in_words(from_time, to_time = 0, include_seconds = false) from_time = from_time.to_time if from_time.respond_to?(:to_time) to_time = to_time.to_time if to_time.respond_to?(:to_time) distance_in_minutes = (((to_time - from_time).abs)/60).round distance_in_seconds = ((to_time - from_time).abs).round case distance_in_minutes when 0..1 return (distance_in_minutes == 0) ?
