Dynamic attributes
If you have a method or attribute in a class, you could invoke the send() method in order to call those
methods or attributes.
In my case, I was confused when I was trying to do a validator for my class Transaction which has
another class associated Account, and there is a class called Entity.
I needed validate that an specific account was created in the Account model and belonged to the
same entity.

problems
Problem topic: postgres
-> Error: psql: could not connect to server: No such file or directory
-> The solution which worked for me:
a pid file was blocking postgres from starting up. To fix it:
rm /usr/local/var/postgres/postmaster.pid
and then all is well.
