Ruby on rails 通过向中间添加信息，您有很多联系吗

我有两个模型，中间有一个模型

class Integration < ActiveBase
  has_many :integration_records
  has_many :records, through: :intragration_records
end

class IntegrationRecords < ActiveBase
 belongs_to :integrations
 belongs_to :records
end

class Records < ActiveBase
  has_many :integration_records
  has_many :integrations, through: :intragration_records
end

这失败了。。。我注意到它会自动为用户创建一个记录

 Integration.create!(whatever_data).integration_records.create(data: {})

所以下一个想法是：

 Integration.create!(whatever_data).integration_records.create(data: {}).records.update(whatever)

没用。救人

也许你可以一步一步地尝试。 1-创建集成 2-创建集成记录 3-创建记录

integration = Integration.create!(whatever_data)
integration_record = integration.integration_records.create!(data: {})
record = integration_record.records.create!(data: {})

---

您可以添加一个事务，以确保只有在创建集成记录和记录时，集成才会被记录。

这就是现在我得到的错误：找不到名称记录的关联。它已经定义好了吗？`哇，是的，那不行，只接受父->子模型中的嵌套属性。片刻运气好吗？见我的另一个问题：

integration = Integration.create!(whatever_data)
integration_record = integration.integration_records.create!(data: {})
record = integration_record.records.create!(data: {})

class Integration < ActiveBase
  has_many :integration_records
  has_many :records, through: :intragration_records
end

class IntegrationRecords < ActiveBase
 belongs_to :integrations
 belongs_to :records
end

class Records < ActiveBase
  has_many :integration_records
  has_many :integrations, through: :intragration_records
end

i = Integration.create!(data)
i.records << Record.create!(data)
