Sorry, I primarily focus on Ruby. However, check out their docs at https://fullcalendar.io/docs/ to see some of their examples that they have.

The RestClient appears to be returning an Unauthorized response and your seeds file isn’t taking that into consideration. Hope that helps.

I will plan on covering FineUploader with a Shrine series. Thank you for the suggestion.

Great question. It really depends on the complexity to which you've modified the datatables. If you are using server side data and a full text engine, then I would store the 'yes' and 'no' values as part of the indexed data.

If you're using Rails 5.1.x then you could also use a virtual attribute to search on instead of the integer column.
