What are the open projects with the latest version of RubyOnRails (from 4.0) for self-study?

Question

Ruby on Rails

Good day.
Recommend open source projects with the latest version of RubyOnRails (from 4.0) for self-study.
First of all, it is interesting to look at typical solutions:
- use of common gems (devise, rails_admin...)
- beautiful front-end framework (bootstap, compass, blueprint...)
- trendy HAML\SASS, etc.
PS
There was a similar question toster.ru/q/52316, but it's important for me that the examples were on the latest version of rails + best practices.
Thank you!

Answer 1

The other day I looked at the sources of Rosvyborov https://github.com/fbkinfo/rosvybory
In general, you can just take the search on the github and use it ;-)
The output is something like this:
https://github.com/railstutorial/sample_app_rails_4
https:// github.com/clayallsopp/rubymotion-tutorial
https://github.com/railstutorial/sample_app
https://github.com/mhartl/sample_app
There are also separate repositories with best practices.
