ActiveRecord test Greater/Lesser Than inside Hash Condition

Question

The Question: Is it possible to test within a hashed condition if an attribute of a joined table is greater/lesser than a value

An example: test if actors age is greater than ageVariable:

• Is it possible to write instead of the ARRAY CONDITION:

  ageVariable = 36<br> Movie.includes(:actors).where("actors.age > ?", ageVariable)
  

• The HASH CONDITION something like:

  ageVariable = 36
  Movie.includes(:actors).where(:actors => { :age => COMPARE_LOGIC })
  # Where COMPARE_LOGIC is something like: (:age > ageVariable)

Only equality, range and subset checking are possible with Hash conditions.
