ActiveRecord关联has_one＆has_many关联表

Question

我试图设置两个模型，并在它们之间建立关联表。我定义我的模型协会评为例如：

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 

我的联想：

class HomebaseAddress < ApplicationRecord 
    belongs_to :homebase 
    belongs_to :address 
end 

我的情况下创建OK：

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

然而，

homebase.addresses 

给以下错误：

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

我在这里错过了什么？感谢堆！

Answer 1

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

您的问题是在固定课室模型的相关项目。你有​​而不是homebase_addresses

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