has_one和has_many關聯表的ActiveRecord關聯

Question

我正在嘗試建立兩個模型，它們之間有關聯表。 我已經定義了我的模型關聯：

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

而我的協會：

 class HomebaseAddress < ApplicationRecord
   belongs_to :homebase
   belongs_to :address
 end

我的實例創建成功：

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

然而，

homebase.addresses

給出以下錯誤：

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

我在這里想念什么？ 謝謝堆！

Answer 1

ActiveRecord :: HasManyThroughAssociationNotFoundError：在模型Homebase中找不到關聯：homebase_address

您的問題出在您的Homebase模型中。 您有homebase_address而不是homebase_addresses

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