Question

How would I parse my start_at column to be three different fields for hours, minutes and seconds instead of just one?

Note: I want to keep it as one column and not make three different ones.

Here is my code:

Table:

class CreateTimers < ActiveRecord::Migration
  def change
    create_table :timers do |t|
      t.time :start_at

      t.timestamps
    end
  end
end

Form:

<%= form_for(@timer) do |f| %>

  <div class="form-inputs">
    <%= f.text_field :start_at %>
  </div>

  <div class="form-actions">
    <%= f.submit 'Start', :class => 'btn-primary span3' %>
  </div>
<% end %>

If you just want to split time to three separate inputs you can use the time_select helper.

Otherwise use the strftime method; Check http://strfti.me for more help.
