Error #1: Glyphicons on Heroku
If you have a problem with the glyphicons not displaying on being deplyed to Heroku, here's what I did based on Lee's suggestion, which worked:
"@import 'bootstrap-sprockets';" should be added to the bootstrap.css.scss file and "config.assets.precompile += %w( *.svg *.eot *.woff *.ttf )" should be added to production.rb. The precompiling of bootstrap changed in recent versions and interacts differently with Rails 4.
Error#2.Update button not working.
This was laughable because I went through my code and Mattan, the instructor's code placing them side by side and found nothing, and as is often the case, I had forgotten to close a piece of code. (The most important lesson in coding: close what you open.)
Amazon S3 has a free basic plan, in case you guys are looking at a storage format.
I'm looking to take up Ruby seriously now. After sifting through many reviews online, I'm settled on Tealeaf Academy. There's something straight and honest about the way they've presented themselves.
I'm off to my first Meetup in a few hours, will post the details. Happy coding!
