Erick said almost 8 years ago on FullCalendar Events and Scheduling :

Greetings:

I enjoyed your video_cast episode on full_calendar and have tried to implement, but seem to be missing some key parts:  1) you mention visitor/view, but give no background on who/what/why that view is needed, nor what its db would contain, 2) using Ruby 2.4.0-rc1 and rails 5.0.1, my application tries to open html code instead of json -- how dit you create your scaffold/modify routes/or ?? to stop that behavior for the full_calendar actions?, and finally, 3) do you have a copy of this rails app demo for download?

Would like to know if this is a rails 5/ruby issue or my bad typing. 

Thanks for your consideration.
