|
|
# The Date Helper primarily creates select/option tags for different kinds of dates and times or date and time
|
|
# 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 <tt>select_month</tt> 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 <tt>select_month</tt> 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, Date or DateTime objects or integers as seconds.
|
|
# Pass <tt>include_seconds: true</tt> 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

|
|
# 59 days, 23 hrs, 59 mins, 30 secs <-> 1 yr minus 1 sec # => [2..12] months
|
|
# 1 yr <-> 1 yr, 3 months # => about 1 year
|
|
# 1 yr, 3 months <-> 1 yr, 9 months # => over 1 year
|
|

|
|
# attribute (identified by +method+) on an object assigned to the template (identified by +object+).
|
|
#
|
|
# ==== 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_two_digit_numbers</tt> - Set to true if you want to display two digit month and day numbers (e.g.
|
|
# "02" instead of "February" and "08" instead of "8").
|
|
# * <tt>:use_short_month</tt> - Set to true if you want to use abbreviated month names instead of full
|
|
# month names (e.g. "Feb" instead of "February").
|
|
# * <tt>:add_month_numbers</tt> - Set to true if you want to use both month numbers and month names (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' 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> to
|
|
# 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>:selected</tt> - Set a date that overrides the actual value.
|
|
# * <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.
|
|
# * <tt>:with_css_classes</tt> - Set to true if you want assign different styles for 'select' tags. This option
|
|
# automatically set classes 'year', 'month', 'day', 'hour', 'minute' and 'second' for your 'select' tags.
|
|
#
|
|
# If anything is passed in the +html_options+ hash it will be applied to every select tag in the set.
