- # 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:
- #
- # * <tt>:prefix</tt> - 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.
- # * <tt>:include_blank</tt> - set to true if it should be possible to set an empty date.
- # * <tt>:discard_type</tt> - 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 <tt>:prefix</tt>) instead of
- # "date[month]".
- module DateHelper
- # Reports the approximate distance in time between two Time or Date objects or integers as seconds.
- # Set <tt>include_seconds</tt> to true if you want more detailed approximations when distance < 1 min, 29 secs
- # Distances are reported based 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 <tt>include_seconds</tt> = 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

- # Returns a set of select tags (one for year, month, and day) pre-selected for accessing a specified date-based
- # attribute (identified by +method+) on an object assigned to the template (identified by +object+). You can
- # the output in the +options+ hash.
- #
- # ==== Options
- # * <tt>:use_month_numbers</tt> - Set to true if you want to use month numbers rather than month names (e.g.
- # "2" instead of "February").
- # * <tt>:use_short_month</tt> - Set to true if you want to use the abbreviated month name instead of the full
- # name (e.g. "Feb" instead of "February").
- # * <tt>:add_month_number</tt> - Set to true if you want to show both, the month's number and name (e.g.
- # "2 - February" instead of "February").
- # * <tt>:use_month_names</tt> - Set to an array with 12 month names if you want to customize month names.
- # Note: You can also use Rails' new i18n functionality for this.
- # * <tt>:date_separator</tt> - Specifies a string to separate the date fields. Default is "" (i.e. nothing).
- # * <tt>:start_year</tt> - Set the start year for the year select. Default is <tt>Time.now.year - 5</tt>.
- # * <tt>:end_year</tt> - Set the end year for the year select. Default is <tt>Time.now.year + 5</tt>.
- # * <tt>:discard_day</tt> - Set to true if you don't want to show a day select. This includes the day
- # as a hidden field instead of showing a select field. Also note that this implicitly sets the day to be the
- # first of the given month in order to not create invalid dates like 31 February.
- # * <tt>:discard_month</tt> - Set to true if you don't want to show a month select. This includes the month
- # as a hidden field instead of showing a select field. Also note that this implicitly sets :discard_day to true.
- # * <tt>:discard_year</tt> - Set to true if you don't want to show a year select. This includes the year
- # as a hidden field instead of showing a select field.
- # * <tt>:order</tt> - Set to an array containing <tt>:day</tt>, <tt>:month</tt> and <tt>:year</tt> do
- # customize the order in which the select fields are shown. If you leave out any of the symbols, the respective
- # select will not be shown (like when you set <tt>:discard_xxx => true</tt>. Defaults to the order defined in
- # the respective locale (e.g. [:year, :month, :day] in the en locale that ships with Rails).
- # * <tt>:include_blank</tt> - Include a blank option in every select field so it's possible to set empty
- # dates.
- # * <tt>:default</tt> - Set a default date if the affected date isn't set or is nil.
- # * <tt>:disabled</tt> - Set to true if you want show the select fields as disabled.
- # * <tt>:prompt</tt> - Set to true (for a generic prompt), a prompt string or a hash of prompt strings
- # for <tt>:year</tt>, <tt>:month</tt>, <tt>:day</tt>, <tt>:hour</tt>, <tt>:minute</tt> and <tt>:second</tt>.
- # Setting this option prepends a select option with a generic prompt (Day, Month, Year, Hour, Minute, Seconds)
- # or the given prompt string.
- #
- # If anything is passed in the +html_options+ hash it will be applied to every select tag in the set.
- #
- # NOTE: Discarded selects will default to 1. So if no month select is available, January will be assumed.
