Turning in miniproject

http://rpy-wdi-miniproject-3.herokuapp.com/

There's quite a few features that I didn't really figure out how to work in. It's a little difficult for me since I'm kinda bad at translating what I want my app to do into actual requirements and specifications...are there more advanced practice homeworks/labs for me to work on, especially ones that use RSpec/Cucumber? I think that might help me get better at putting an app together.
Overall good database layout
