ActiveRecord關聯has_one＆has_many關聯表

Question

我試圖設置兩個模型，並在它們之間建立關聯表。我定義我的模型協會評爲例如：

class Homebase < ApplicationRecord 
    has_many :homebase_addresses 
    has_many :addresses, through: :homebase_address 
end 

class Address < ApplicationRecord 
    has_one :homebase_address 
    has_one :homebase, through: :homebase_address 
end 

我的聯想：

class HomebaseAddress < ApplicationRecord 
    belongs_to :homebase 
    belongs_to :address 
end 

我的情況下創建OK：

homebase = Homebase.create 
address = Address.create 
homebase_address = HomebaseAddress.create(homebase: homebase, address: address) 

然而，

homebase.addresses 

給以下錯誤：

ActiveRecord::HasManyThroughAssociationNotFoundError: 
     Could not find the association :homebase_address in model Homebase 

我在這裏錯過了什麼？感謝堆！

Answer 1

ActiveRecord::HasManyThroughAssociationNotFoundError: Could not find the association :homebase_address in model Homebase

您的問題是在固定課室模型的相關項目。你有​​而不是homebase_addresses

class Homebase < ApplicationRecord 
    has_many :homebase_addresses 
    has_many :addresses, through: :homebase_addresses 
              #^^^^^ 
end
