Rails 6.0 has_many - belongs_to无法识别外键

问：

我有 2 个模型 Loan：：Transaction 和 Loan：：Transaction：：Transition。它们都在文件夹“models”和“loan”中。第二个也在文件夹“transaction”中。

1 Loan：：Transaction 有很多 Loan：：Transaction：：Transition 1 Loan：：Transaction：：Transition
属于 1 Loan：：Transaction

Loan：：Transaction：：Transition 的列loan_transaction_id

迁移：

class CreateLoanTransactionTransitions < ActiveRecord::Migration[6.0]
  def up
    create_table :loan_transaction_transitions, id: :uuid do |t|
      t.timestamps
      t.references :loan_transaction, type: :uuid, null: false, index: true,
                                      foreign_key: { to_table: :loan_transactions }
      t.string :reason
      t.references :made_by, type: :uuid, null: true, foreign_key: { to_table: :users }
    end
    add_column :loan_transaction_transitions, :from_status, :transaction_status, null: false
    add_column :loan_transaction_transitions, :to_status,   :transaction_status, null: false
  end

  def down
    drop_table :loan_transaction_transitions
  end
end

过渡类：

class Loan::Transaction::Transition < ApplicationRecord
  validates :to_status, presence: true
  validates :from_status, presence: true
  validates :loan_transaction_id, presence: true

  belongs_to :made_by, class_name: 'User', foreign_key: 'made_by_id', optional: true
  belongs_to :loan_transaction, class_name: 'Loan::Transaction', foreign_key: 'loan_transaction_id', inverse_of: :transitions
end

交易类：

class Loan::Transaction < ApplicationRecord
  extend ActiveSupport::Concern
  
  has_many :transitions, class_name: 'Transaction::Transition', dependent: :destroy, foreign_key: 'loan_transaction_id', inverse_of: 'loan_transaction'
  accepts_nested_attributes_for :transitions
end

当我尝试执行“Loan：：Transaction.first.transitions”之类的操作时，出现以下错误： ActiveRecord：：StatementInvalid （PG：：UndefinedColumn： ERROR： column loan_transaction_transitions.transaction_id does not exist） 第 1 行：......作为“loan_transaction_transitions”中的一员，其中“loan_tran......

但我试图以多种方式说明这一点。到目前为止没有任何效果。我正在为postrgreSQL使用docker-compose 3.7，为Web服务器使用另一个容器。
