Separate date and time form fields in Rails

Question

I have an ActiveRecord model Eventwith a datetime column starts_at. I would like to present a form, where date and time for starts_at

Answer 1

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.
