Separate date and time form fields in Rails
Solution 1
Was looking at this today for a Rails project, and came across this gem:
https://github.com/shekibobo/time_splitter
Setting DateTimes can be a difficult or ugly thing, especially through a web form. Finding a good DatePicker or TimePicker is easy, but getting them to work on both can be difficult. TimeSplitter automatically generates accessors for date, time, hour, and min on your datetime or time attributes, making it trivial to use different form inputs to set different parts of a datetime field.
Looks like it would do the job for you
Solution 2
Do you have to have a text_field
in the view?
As far as I can tell, you can have a date_time
field and then just use two different input fields to set the different parts of the field.
form_for @event do |f|
f.date_select :starts_at
f.time_select :starts_at, :ignore_date => true
f.submit
end
Since the rails date and time select helpers set five different parameters (starts_at(1i)
for the year part, 2i
for the month part, and so on), that means that the date_select
only sets them for the date part, while if you pass :ignore_date => true
to the time_select
, it will only set the hour and minute part.
If you must have a text_field
I'm not sure how to do it, but it might be possible to do using some jQuery magic before setting the datetime parameters before sending the form.
Solution 3
Using a date_select
and time_select
is a good way to go.
However, I wanted a text_field
for the date (so I can use a JavaScript date picker).
Using strong_parameters or Rails 4+:
models/event.rb
# Add a virtual attribute
attr_accessor :start_at_date
views/events/_form.html.haml
- # A text field for the date, and time_select for time
= f.label :start_at
= f.text_field :start_at_date, value: (f.object.start_at.present? ? f.object.start_at.to_date : nil)
= f.time_select :start_at, :ignore_date => true
controllers/events_controller.rb
# If using a date_select, time_select, datetime_select
# Rails expects multiparameter attributes
# Convert the date to the muiltiparameter parts
def event_params
if !!params[:event] && (params[:event]["start_at(4i)"].present? || params[:event]["start_at(5i)"].present?)
if params[:event][:start_at_date].present?
start_at_date = params[:event][:start_at_date]
else
start_at_date = Date.today
end
year = start_at_date.match(/^(\d{4})[\-\/]/)[1]
month = start_at_date.match(/[\-\/](\d{2})[\-\/]/)[1]
day = start_at_date.match(/[\-\/](\d{2})$/)[1]
params[:event]["start_at(1i)"] = year
params[:event]["start_at(2i)"] = month
params[:event]["start_at(3i)"] = day
end
...
Solution 4
Elegant solution may provide date_time_attribute gem:
class MyModel < ActiveRecord::Base
include DateTimeAttribute
date_time_attribute :starts_at
end
It will allow you to set starts_at_date
and starts_at_time
separately:
form_for @event do |f|
f.text_field :starts_at_date
f.text_field :starts_at_time
f.submit
end
# this will work too:
form_for @event do |f|
f.date_select :starts_at_date
f.time_select :starts_at_time, :ignore_date => true
f.text_field :starts_at_time_zone
f.submit
end
# or
form_for @event do |f|
f.date_select :starts_at_date
f.text_field :starts_at_time
f.submit
end
It will also allow you to play with time zones, use Chronic etc.

I have an ActiveRecord model
Event
with a datetime columnstarts_at
. I would like to present a form, where date and time forstarts_at
are chosen separately (e.g."23-10-2010"
for date and"18:00"
for time). These fields should be backed by the single columnstarts_at
, and validations should preferably be againststarts_at
, too.I can of course muck around with virtual attributes and hooks, but I would like a more elegant solution. I have experimented with both
composed_of
(rdoc), and attribute-decorator (lighthouse discussion, github) without success.Below is a rough outline of what I would like..
class Event < ActiveRecord::Base validates_presence_of :start_date end # View # On submission this should set start_date. form_for @event do |f| f.text_field :starts_at_date # date-part of start_date f.text_field :starts_at_time_of_day # time-of-day-part of start_date f.submit end
Any help appreciated.

benvds almost 13 yearsNo it's not a design issue. The data should be a single column while the form builder should handle 2 different attributes for that same column.
-
benvds almost 13 yearsNice, seems to work and a good enough of a solution. But what I'd really like to see is a way to divide and reconstruct attributes around the form helper. E.g. before_form_build & before_form_validation.

Frost almost 12 yearsThen I think you'd need to do some manual hacking on the params hash.

Jonathan Clark over 10 yearsIs there a way of setting timezone for this gem? It always saves in UTC.
-
asgeo1 over 10 yearsIn my testing it was using the configured time zone. Are you sure you were setting it correctly?
-
d_rail almost 10 yearsAre you sure you can mix
date_select
andtext_field
? I wasn't able to use atext_field
andtime_select
and there is no documentation showing you can. -
steve klein about 9 yearsI tried to use this gem and ran into a problem right away stackoverflow.com/questions/29858627/…

alexventuraio over 7 yearsWhy do you use
!!
in the if comparison? What does that means? -
d_rail over 7 yearsConverts the value into a boolean (stackoverflow.com/questions/524658/what-does-mean-in-ruby), probably not required.
-
alexventuraio over 7 yearsYeah thats what I though but anyway thank you for the response. :)

Sidney over 6 yearsYou don't need to include the DateTimeAttribute module, as said in the README of the repository of the gem: github.com/einzige/date_time_attribute#rails-users
