Rails6.0由于无法识别外键而导致_many-belongs_to失败

Question

我有两个模型Loan:：Transaction和Loan:；Transaction:：Transition。它们都在文件夹"中；模型"；而内部"；贷款"；。第二个也是在文件夹"内；交易"；。

1贷款：：交易有许多贷款：：事务：：转换
1贷款：：业务：：转换属于1贷款：事务

Loan:：Transaction:：Transition的列为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

过渡等级：

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

交易类别：

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

当我尝试做一些类似"；贷款：：交易。首先。过渡；我得到以下错误：ActiveRecord:：StatementInvalid(PG:：UndefinedColumn:ERROR:列loan_transaction_transactions.transaction_id不存在(第1行：。。。作为一个FROM"；transaction_transitions"；其中"；loan_tran。。。

但我试图在很多方面具体说明这一点。到目前为止一切都不起作用。我为postrgreSQL使用dockercompose3.7，为web服务器使用另一个容器。

我设法"修复"；通过改变迁移字段"；贷款交易->quot；交易"；和Transition类中的外键值。不理想的坚韧
