This is a simple gem for Active Admin that just adds support for Time picker.

It supports both ActiveRecord for relational databases and Mongoid for MongoDB schemaless database.

For Date/Time picker widget, see just-datetime-picker.

Here comes a quick code sample. Sorry, currently no detailed docs.

That should create nice date/time picker for User#notify_at.

Associated column in the DB should can have type of :time. It has to be nullable.

To delete previously stored time just make all fields blank (hour and minute).

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.time  :notify_at # You can also use :integer with :limit => 6

      t.timestamps
    end

  end
end

class User < ActiveRecord::Base
  just_define_time_picker :notify_at, :add_to_attr_accessible => true
  validates :notify_at, :presence => true
end

class User
  include Mongoid::Document
  field :notify_at, type: Time
  just_define_time_picker :notify_at, :add_to_attr_accessible => true
end

You must place “mongoid” gem BEFORE “just-time-picker” gem in your Gemfile!

ActiveAdmin.register User do
  form do |f|
    f.inputs do
      f.input :notify_at, :as => :just_time_picker
    end

    f.buttons
  end
end

The gems are hosted at Rubygems.org. Make sure you’re using the latest version of rubygems:

$ gem update --system

Then you can install the gem as follows:

$ gem install just-time-picker

Add to your Gemfile:

gem "just-time-picker"

and then type:

bundle install

The source code is available at github.com/saepia/just-time-picker. You can either clone the git repository or download a tarball or zip file. Once you have the source, you can unpack it and use from wherever you downloaded.

If you use Rails >= 3.1 AND ActiveAdmin >= 0.5.0 just add this line to active_admin.css.scss

@import "just_time_picker/base";

Otherwise, just manually append the code from this file to your CSS stylesheet.

In ActiveAdmin 0.4.x you must strip body.active_admin from CSS declarations.
