Xdan Datetimepicker Rails

This gem adds @xdan's datetimepicker to the Rails asset pipeline.

Installation

Add this line to your application's Gemfile:

gem 'xdan-datetimepicker-rails'

And then execute:

$ bundle

Or install it yourself as:

$ gem install xdan-datetimepicker-rails

Usage

Require the jquery file into your application.js.coffee file:

#= require jquery.xdan.datetimepicker

Import the stylesheet in your application.css.scss file:

@import "jquery.xdan.datetimepicker";

Start using it!

# /app/assets/javascripts/datetimepicker.js.coffee

#= require jquery.xdan.datetimepicker

@setupDateTimePicker = (container) ->
  defaults = {
    formatDate: 'y-m-d',
    format: 'Y-m-d H:i',
    allowBlank: true,
    defaultSelect: false,
    validateOnBlur: false
  }

  entries = $(container).find('input.datetimepicker')
  entries.each (index, entry) ->
    options = $(entry).data 'datepicker-options'
    $(entry).datetimepicker $.extend(defaults, options)

$ ->
  setupDateTimePicker $('body')

See the detailed documentation for more options. When the site is back up I'll try to port some of them into this README or move them to the official repo of datetimepicker.

SimpleForm Integration

# /app/inputs/datetimepicker_input.rb

class DatetimepickerInput < SimpleForm::Inputs::StringInput
  def input_html_classes
    super.push("datetimepicker")

  end

  def input_html_options
    super.tap do |opts|
      opts[:data] ||= {}
      opts[:data].merge! datepicker_options
      opts[:value] ||= value
    end
  end

  def value
    val = object.send(attribute_name)
    return DateTime.new(val.year, val.month, val.day, val.hour, val.min).strftime("%Y-%m-%d %H:%M") if val.is_a?(Time)
    return val if val.nil?
    val.to_s
  end

  private
    def datepicker_options
      options = self.options.fetch(:datepicker_options, {})
      options = Hash[options.map{ |k, v| [k.to_s.camelcase(:lower), v] }]
      { datepicker_options: options }
    end
end

Formtastic Integration
