Introduction

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

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

For Time picker widget, see just-time-picker.

Usage

Code samples

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

That should create nice date/time picker for User#born_at. Associated column in the DB should be nullable.

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

Migration (if you use ActiveRecord)

class CreateUsers < ActiveRecord::Migration
  def change
    create_table :users do |t|
      t.datetime  :born_at

      t.timestamps
    end

  end
end

Model

ActiveRecord

class User < ActiveRecord::Base
  just_define_datetime_picker :born_at, :add_to_attr_accessible => true
  validates :born_at, :presence => true
end

Mongoid

class User
  include Mongoid::Document
  field :born_at, type: DateTime
  just_define_datetime_picker :born_at, :add_to_attr_accessible => true
end

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

ActiveAdmin

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

    f.buttons
  end
end

Installation

Code itself

Gems

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-datetime-picker

Bundler

Add to your Gemfile:

gem "just-datetime-picker"

and then type:

bundle install

From the GitHub source

The source code is available at github.com/saepia/just-datetime-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.

Assets

CSS

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

@import "just_datetime_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.

JavaScript

If you use nested set and dynamically create date or date/time pickers, they won’t be active by default due to bug in Active Admin.

To overcome that, if you use Rails >= 3.1 just add this line to active_admin.js

//= require just_datetime_picker/nested_form_workaround

Otherwise, just manually append the code from this file to your JS script.
