Create your own scheduler within 10 minutes with Rails and dhtmlxScheduler

Today I am going to show you how to create a Google-like scheduler with your Rails application. Here we are going to  use dhtmlxScheduler. It is a Javascript event calendar. Intuitive drag-and-drop interface allows the end users to quickly manage events and appointments in different views: Day, Week, Month, Year, Agenda, Timeline, etc. For more info regarding dhtmlx click here.

Step- 1: Let's first create a new Rails application for our scheduler

$ rails new my_scheduler

Step- 2: Create  a ‘Home’ controller

$ rails g controller home index

Step – 3 open config/routes.rb and replace as following

get ‘home/index’


root ‘home#index’

Step – 4 Start Rails server now and test it in your browser with http://localhost:3000

$ rails s

Step- 5 Now download the dhtmlxScheduler. Download open source from standard edition box. Now unzip the file

Add following files to vendor/assets/javascripts codebase/dhtmlxscheduler.js codebase/ext codebase/locale

and following files to vendor/assets/stylesheets

codebase/dhtmlxscheduler.css codebase/dhtmlxscheduler_classic.css codebase/dhtmlxscheduler_flat.css codebase/dhtmlxscheduler_glossy.css

Then we need to create an assets folder in the public directory and copy following files there.

codebase/imgs codebase/imgs_dhx_terrace codebase/imgs_flat codebase/imgs_glossy

Now open config/initializers/assets.rb and add our newly added css and js to asset precompile settings:

Step – 6: Open views/layouts/application.html.erb and include include dhtmlxscheduler.js and dhtmlxscheduler.css

Step- 7: Now open your newly created home/index.html.erb.It will display our scheduler.

Now we add a container for our scheduler and initialize our event calendar

Step- 8: Restart your server and check your browser at http://localhost:3000

Step- 9: So dhtmlxSheduler is initialized and we may proceed to further settings. Let’s create a model for an event.  Run the following command

$ rails g model Event start_date:datetime end_date:datetime text:string

Run database migration

$ rake db:migrate

Step- 10: Now open config/routes.rb and add another route for data loading

get “home/data”, to: “home#data”, as: :data

step : 11:

Open controllers/home_controller.rb and add ‘data’ action to it.

step -12 Add another route to perform antoher db relate action

get “home/db_action”, to: “home#db_action”, as: :db_action

Step – 13- To save the changes in scheduler we need to use DataProcessor. Open app/views/home/index.html.erb.

Now add following lines to your index.html.erb script tags:

If you want to use a post request for changing the data in your database, then you need to specify Transaction Mode dataProcessor = POST. Moreover, you need to change the corresponding route to:

post “home/db_action”, to: “home#db_action”, as: :db_action

And you need to add following line in your controllers/application_controller.rb

protect_from_forgery with: :null_session

instead of

protect_from_forgery with: :exception

Step- 15: Finally we are ready to see the result: run your server

$ rails s

The whole source code is available at my git repository.

All set! Now, go to your browser and start scheduling your day!!

Have a happy coding!!
