Module: ActionView::Helpers::DateHelper
Overview
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 instead of date 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”.

#date_select(object_name, method, options = {}, html_options = {}) ⇒ Object
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
). It’s possible to tailor the selects through the options
hash, which accepts all the keys that each of the individual select builders do (like :use_month_numbers
for select_month) as well as a range of discard options. The discard options are :discard_year
, :discard_month
and :discard_day
. Set to true, they’ll drop the respective select. Discarding the month select will also automatically discard the day select. It’s also possible to explicitly set the order of the tags using the :order
option with an array of symbols :year
, :month
and :day
in the desired order. Symbols may be omitted and the respective select is not included.
Pass the :default
option to set the default date. Use a Time object or a Hash of :year
, :month
, :day
, :hour
, :minute
, and :second
.
Passing :disabled => true
as part of the options
will make elements inaccessible for change.
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.
Examples
# Generates a date select that when POSTed is stored in the post variable, in the written_on attribute
date_select("post", "written_on")
# Generates a date select that when POSTed is stored in the post variable, in the written_on attribute,
# with the year in the year drop down box starting at 1995.
date_select("post", "written_on", :start_year => 1995)
# Generates a date select that when POSTed is stored in the post variable, in the written_on attribute,
# with the year in the year drop down box starting at 1995, numbers used for months instead of words,
# and without a day select box.
date_select("post", "written_on", :start_year => 1995, :use_month_numbers => true,
:discard_day => true, :include_blank => true)
# Generates a date select that when POSTed is stored in the post variable, in the written_on attribute
# with the fields ordered as day, month, year rather than month, day, year.
date_select("post", "written_on", :order => [:day, :month, :year])
# Generates a date select that when POSTed is stored in the user variable, in the birthday attribute
# lacking a year field.
date_select("user", "birthday", :order => [:month, :day])
# Generates a date select that when POSTed is stored in the user variable, in the birthday attribute
# which is initially set to the date 3 days from the current date
date_select("post", "written_on", :default => 3.days.from_now)
# Generates a date select that when POSTed is stored in the credit_card variable, in the bill_due attribute
# that will have a default day of 20.
date_select("credit_card", "bill_due", :default => { :day => 20 })
The selects are prepared for multi-parameter assignment to an Active Record object.
Note: If the day is not included as an option but the month is, the day will be set to the 1st to ensure that all month choices are valid.

#select_month(date, options = {}, html_options = {}) ⇒ Object
Returns a select tag with options for each of the months January through December with the current month selected. The month names are presented as keys (what’s shown to the user) and the month numbers (1-12) are used as values (what’s submitted to the server). It’s also possible to use month numbers for the presentation instead of names – set the :use_month_numbers
key in options
to true for this to happen. If you want both numbers and names, set the :add_month_numbers
key in options
to true. If you would prefer to show month names as abbreviations, set the :use_short_month
key in options
to true. If you want to use your own month names, set the :use_month_names
key in options
to an array of 12 month names. Override the field name using the :field_name
option, ‘month’ by default.

#select_year(date, options = {}, html_options = {}) ⇒ Object
Returns a select tag with options for each of the five years on each side of the current, which is selected. The five year radius can be changed using the :start_year
and :end_year
keys in the options
. Both ascending and descending year lists are supported by making :start_year
less than or greater than :end_year
. The date
can also be substituted for a year given as a number. Override the field name using the :field_name
option, ‘year’ by default.
Examples
# Generates a select field for years that defaults to the current year that
# has ascending year values
select_year(Date.today, :start_year => 1992, :end_year => 2007)
# Generates a select field for years that defaults to the current year that
# is named 'birth' rather than 'year'
select_year(Date.today, :field_name => 'birth')
# Generates a select field for years that defaults to the current year that
# has descending year values
select_year(Date.today, :start_year => 2005, :end_year => 1900)
# Generates a select field for years that defaults to the year 2006 that
# has ascending year values
select_year(2006, :start_year => 2000, :end_year => 2010)

#time_ago_in_words(from_time, include_seconds = false) ⇒ Object Also known as: distance_of_time_in_words_to_now
Like distance_of_time_in_words, but where to_time
is fixed to Time.now
.
Examples
time_ago_in_words(3.minutes.from_now) # => 3 minutes
time_ago_in_words(Time.now - 15.hours) # => 15 hours
time_ago_in_words(Time.now) # => less than a minute
from_time = Time.now - 3.days - 14.minutes - 25.seconds # => 3 days

#time_select(object_name, method, options = {}, html_options = {}) ⇒ Object
Returns a set of select tags (one for hour, minute and optionally second) pre-selected for accessing a specified time-based attribute (identified by method
) on an object assigned to the template (identified by object
). You can include the seconds with :include_seconds
.
If anything is passed in the html_options hash it will be applied to every select tag in the set.
Examples
# Creates a time select tag that, when POSTed, will be stored in the post variable in the sunrise attribute
time_select("post", "sunrise")
# Creates a time select tag that, when POSTed, will be stored in the order variable in the submitted attribute
time_select("order", "submitted")
# Creates a time select tag that, when POSTed, will be stored in the mail variable in the sent_at attribute
time_select("mail", "sent_at")
# Creates a time select tag with a seconds field that, when POSTed, will be stored in the post variables in
# the sunrise attribute.
time_select("post", "start_time", :include_seconds => true)
# Creates a time select tag with a seconds field that, when POSTed, will be stored in the entry variables in
# the submission_time attribute.
time_select("entry", "submission_time", :include_seconds => true)
# You can set the :minute_step to 15 which will give you: 00, 15, 30 and 45.
time_select 'game', 'game_time', {:minute_step => 15}
The selects are prepared for multi-parameter assignment to an Active Record object.
Note: If the day is not included as an option but the month is, the day will be set to the 1st to ensure that all month choices are valid.
