Ruby on rails Rails 4中生成的错误查询与有许多关系

我正在开发一个带有遗留数据库的rails应用程序，因此我不能遵守这些约定。 我有两种型号：

class Afiliado < ActiveRecord::Base
  self.primary_key = "idAfiliado"

  has_many :registros_odontologicos, 
           class_name: :RegistroOdontologico, 
           foreign_key: 'idRegistroOdontologico'
end


class RegistroOdontologico < ActiveRecord::Base
  self.table_name = "registrosodontologicos"
  self.primary_key = "idRegistroOdontologico"

  belongs_to :_afiliado, class_name: "Afiliado", foreign_key: "afiliado" 
end

我得到一个空结果，但请注意最后一个查询是wrog。查询应为：

  SELECT `registrosodontologicos`.* FROM `registrosodontologicos` WHERE `registrosodontologicos`.`afiliado` = 145

我做错了什么

更新 反向导航功能工作正常

RegistroOdontologico.find(2)._afiliado

生成：

  RegistroOdontologico Load (0.3ms)  SELECT `registrosodontologicos`.* FROM `registrosodontologicos` WHERE `registrosodontologicos`.`idRegistroOdontologico` = 2 LIMIT 1
  Afiliado Load (0.3ms)  SELECT `afiliados`.* FROM `afiliados` WHERE `afiliados`.`idAfiliado` = 145 ORDER BY `afiliados`.`idAfiliado` ASC LIMIT 1

您的配置中有一个错误：

has_many :registros_odontologicos, class_name: :RegistroOdontologico, foreign_key: 'idRegistroOdontologico'
belongs_to :_afiliado, class_name: "Afiliado", foreign_key: "afiliado"

外键

选项不一致。

是<

中的code>外键

选项有很多必须是

外键：“afiliado”

。非常感谢。

has_many :registros_odontologicos, class_name: :RegistroOdontologico, foreign_key: 'idRegistroOdontologico'
belongs_to :_afiliado, class_name: "Afiliado", foreign_key: "afiliado"
