SqlOptimizer
This gem I use for my diploma, it isn't perfect, so I don't recommend to use it. In the future maybe I'll improve it.
SqlOptimizer this is a gem for query optimization in your app. You can use two our method to check you query: anayle
and check_n_plus_one
. This is not so much, but we'll add more in the future. Also you can visit localhost:3000/sql_optimizer to see information about queries in your app.

method to see full information about queries
For example:
