I have a parent table and a child table, I would like to know how do I make a query in the child table but sort by a column of the parent table. I want to know all the children and sort them out by the age of the father.

Considering that there is a has_many/belongs_to relationship between the Pai model and the Filho template, you can do the following: 

Filho.includes('pai').order('pais.idade DESC')

Ready, it will return all the children by the age of the parent.
