Ruby on rails 使用联接搜索rails应用程序查询的范围

很好，我正在尝试创建一个范围，通过关联模型的属性以及模型本身的属性来搜索关联模型的记录

class Payment < ApplicationRecord
  belongs_to :payment_issuer, class_name: 'Balance', foreign_key: 'payment_issuer_id', optional: true
  belongs_to :payment_reciever, class_name: 'Balance', foreign_key: 'payment_reciever_id'
  belongs_to :closure, optional: true

  validates_presence_of :amount, :reference, :status

  scope :for_commerce, -> (commerce) { Payment.joins(payment_reciever: {user: :commerce}).where(
      payment_recievers: {
        users: {
          commerce: commerce
        }
      }
    ) 
  }
  scope :billed_at, -> (date) { where("payments.status ILIKE 'Pago' AND payments.created_at >=?", date) }
  scope :refills, -> { where("payments.status ILIKE 'Recarga'") }
end

但是不要返回任何记录，即使我输入了精确的值

这是回报

Payment Load (3.3ms)  SELECT "payments".* FROM "payments" INNER JOIN "balances" ON "balances"."id" = "payments"."payment_issuer_id" INNER JOIN "users" ON "users"."id" = "balances"."user_id" WHERE "users"."name" = $1 AND "payments"."reference" = $2 LIMIT $3  [["name", "1605895669"], ["reference", "1605895669"], ["LIMIT", 11]]

我也试过了

  scope :search, -> (search) { Payment.joins(payment_issuer: :user).where("payments.reference ILIKE '#{search}' OR payments.payment_issuers.users.name ILIKE '#{search}'") }

但是回来

ActiveRecord::StatementInvalid (PG::FeatureNotSupported: ERROR:  cross-database references are not implemented: payments.payment_issuers.users.name)
LINE 1: ...E (payments.reference ILIKE 'Esteban Chirinos' OR payments.p...

非常感谢您，我希望您的回答有误吗？如果是，请将其添加到您的问题中。我认为您的

where

语句不正确，但如果没有这些信息，很难确定。即使输入值，也不会返回任何记录​​这已经存在了为什么你要做

用户。我喜欢“管理员”

？规范化您的数据…@max向我解释如何规范化我的数据

payments.payment\u issuers.users.name

应该是

users.name

在您的查询中，现在它认为您正在调用[database\u name].[schema].[table].[column]，这是跨数据库查询的正常格式。相反，您只需要[table].[column]，因为联接处理对payments表和payment_issuers表的引用

Payment Load (3.3ms)  SELECT "payments".* FROM "payments" INNER JOIN "balances" ON "balances"."id" = "payments"."payment_issuer_id" INNER JOIN "users" ON "users"."id" = "balances"."user_id" WHERE "users"."name" = $1 AND "payments"."reference" = $2 LIMIT $3  [["name", "1605895669"], ["reference", "1605895669"], ["LIMIT", 11]]

  scope :search, -> (search) { Payment.joins(payment_issuer: :user).where("payments.reference ILIKE '#{search}' OR payments.payment_issuers.users.name ILIKE '#{search}'") }

ActiveRecord::StatementInvalid (PG::FeatureNotSupported: ERROR:  cross-database references are not implemented: payments.payment_issuers.users.name)
LINE 1: ...E (payments.reference ILIKE 'Esteban Chirinos' OR payments.p...
