how to add records to has_many :through association in rails

Question

class Agents << ActiveRecord::Base
  belongs_to :customer
  belongs_to :house
end

class Customer << ActiveRecord::Base
  has_many :agents
  has_many :ho         


        

Answer 1

Another way to add associations is by using the foreign key columns:

agent = Agent.new(...)
agent.house = House.find(...)
agent.customer = Customer.find(...)
agent.save

Or use the exact column names, passing the ID of the associated record instead of the record.

agent.house_id = house.id
agent.customer_id = customer.id
