Ruby, Datetimepicker with Bootstrap 4

(this article was writen in 2016, so this can be obsolete now)

I wrote this article to explain how to install a datetimepicker in a rails project with bootstrap 4. Indeed, I spent a lot of time to find the solution, because it worked only with bootstrap 3.

A datetimepicker is essential to have a much better user experience in your forms.

Here, is what I did to install it :

1 Find the most recent project on github

bootstrap-datetimepicker Don’t install the gem !

2 Install moment-js

Install moment for the format of dates.

In your Gemfile

gem 'momentjs-rails', '>= 2.9.0

In application.js

//= require moment

Don’t forget to re run your server

3 Add the js file in your project

In your javascripts folder

Add the file bootstrap-datetimepicker.js and copy past the content of the file from github project src.


In your application.js

//= require bootstrap-datetimepicker.js

4 Add css file in your project

In your stylesheets folder

Add the file bootstrap-datetimepicker.css and copy past the content of build folder in github project


In your application.scss

*= require bootstrap-datetimepicker

Now the install is done, re run your server.

5 Complete your view

If you are using simple form for, add this code in your input:

 as: :string, input_html: { class:"datetimepicker" }

The class “datetimepicker” that it will be called in the script

Add the basic script in your view

<script type="text/javascript">
    format: "YYYY-MM-DD";

Here the documentation

Now it is work ! but the icons are not appear, indeed, because of the new version of bootstrap, you have to replace some code in your js file.

6 Fix the icons in js file

In javascripts/bootstrap-datetimepicker.js

Replace this code :

  icons: {
      time: 'glyphicon glyphicon-time',
      date: 'glyphicon glyphicon-calendar',
      up: 'glyphicon glyphicon-chevron-up',
      down: 'glyphicon glyphicon-chevron-down',
      previous: 'glyphicon glyphicon-chevron-left',
      next: 'glyphicon glyphicon-chevron-right',
      today: 'glyphicon glyphicon-screenshot',
      clear: 'glyphicon glyphicon-trash',
      close: 'glyphicon glyphicon-remove'

By font-awesome icons:

icons: {
  time: 'fa fa-clock-o',
  date: 'fa fa-calendar',
  up: 'fa fa-chevron-up',
  down: 'fa fa-chevron-down',
  previous: 'fa fa-chevron-left',
  next: 'fa fa-chevron-right',
  today: 'glyphicon glyphicon-screenshot',
  clear: 'fa fa-trash',
  close: 'fa fa-times'

Great ! it is working
