See question on stack overflow: http://stackoverflow.com/questions/28595636/rails-4-how-to-give-alias-names-to-includes-and-joins-in-active-record-que

- Model Student and model Teacher are both STI models with super class model User
- Model Story is a STI model with super class model Task
- includes() and joins(), both fails

Rails alias naming convention (includes() and joins())

- One model as parameter
  - is base model (includes(:users))

In Ruby, self is a special variable that always references the current object.

• Inside class or module definition, self refer to the Class or Module object.
• Inside instance method, self refer to future instance object.
• Inside class method, self refer to the class.i

NGINX Tuning For Best Performance

For this configuration you can use web server you like, i decided, because i work mostly with it to use nginx.

Generally, properly configured nginx can handle up to 400K to 500K requests per second (clustered), most what i saw is 50K to 80K (non-clustered) requests per second and 30% CPU load, course, this was 2 x Intel Xeon with HyperThreading enabled, but it can work without problem on slower machines.

You must understand that this config is used in testing environment and not in production so you will need to find a way to implement most of those features best possible for your servers.
