Rails Activerecord Reverse Association

I have models: 

class Materialtitle < ActiveRecord::Base
  has_many :edocs
end

class Edoc < ActiveRecord::Base
     belongs_to :materialtitles
end

I may do Materialtitle.find(2).edocs.
I would like to do something like Edoc.find(10).materialtitles. But It returns nil.

Could someone help me?

If it is many-to-one then it should be belongs_to :materialtitle (singular) and your DSL should look like:

 Edoc.includes(:materialtitle).find(10).materialtitle
