Hi! Almost a year later and this episode is still helping people. Thanks so much! I modified the code a bit (mainly CSS so shouldn't cause too much of a problem). My overall plan is to add users and play around with that, but I'm getting ahead of myself.

I tried to upload it to Heroku but I get a 500 error when I load the page and try to click on a day to add an event. Logs tell me it's getting a 500 on `/events/new?_=1494878802742`. Could you potentially think of a reason why?

I did switch from sqlite3 to postgreSQL. Could that be causing the problem? I switched because Heroku plays nicer with pg than sqlite.

Edit: I feel like I should mentioned that it works perfectly when I test locally with the rails server

Hi again! Thanks for replying. I figured it out. Turns out I'm just a silly programmer and forgot to run my rake tasks. Works like a charm now.
