TimeSplitter

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 any datetime or time attribute, making it trivial to use different form inputs to set different parts of a datetime field.

This gem is based on SplitDatetime by Michi Huber. TimeSplitter improves on the gem, updating for Rails 4, adding time accessors, and providing a safer and more consistent default setting.

Example Usage

In your Gemfile:

ruby gem "time_splitter"

After bundling, assuming you have an Event model with a starts_at attribute, add this to your model:

ruby class Event < ActiveRecord::Base extend TimeSplitter::Accessors split_accessor :starts_at end

In your view:

erb <%= simple_form_for @event do |f| %> <%= f.input :starts_at_date, as: :string, input_html: { class: 'datepicker' } %> <%= f.input :starts_at_hour, collection: 0..24 %> <%= f.input :starts_at_min, collection: [0, 15, 30, 45] %> <%= f.input :starts_at_time, as: :time_select <%= ... %> <% end %>

Add your js datepicker and you’re good to go. (Of course, this also works with standard Rails form helpers).

Options

You can specify the date format for the view:

ruby split_accessor :starts_at, format: "%D"

See Time#strftime for formats. Default is "%F".

You can specify multiple datetime fields to split:

ruby split_accessor :starts_at, :ends_at, :expires_at, format: "%D"
