More practice for rails

Does someone have same tasks to practice?
On the same level like michael hartl twitter or little bit harder.
It will be amazing to have a solution off that task

I can't find some exercise for rails unlike for PHP

Get and read Justin Weiss’s “Practicing Rails” book (https://www.justinweiss.com/practicing-rails/).

That said, pick one “smaller” aspect out of rails (say ActiveRecord::Serializers) and go to town building practice apps with models and tests and just work it until you know it cold.

In fact, work on testing; that’s a huge aspect that a lot of folks don’t have enough expertise on.

Small ideas, work them, like kata.

I was thinking to use someone else project and develop that project from
scratch because he has solution.

I know about small idea then to upgrade it some bigger thing, but i
would rather use someone else web application and practice on it.

If you know some web project (open source) which are finished let me
know

Thank you for advice for testing
