List through has_many

I have this db schema

class User
  has_many :accounts
end

class Account
  belongs_to :user
  belongs_to :biller
end

class Biller
  has_many :accounts
end

How to get a list of billers of the user?

billers = user.?

Add has_many association with thorough option:

class User
  has_many :accounts
  has_many :billers, through: :accounts 
end

class Account
  belongs_to :user
  belongs_to :biller
end

class Biller
  has_many :accounts
end

And use it like follow:

billers = user.billers
