如何通过迁移创建 table 关系 Knex.js/express？

Question

我拥有为后端应用程序创建所需的所有 table，但是当我尝试为关系添加外键时，它会在调用迁移时抛出错误。 数据库是postgreSQL 目标：我想再制作 1 个 table，它引用将所有 table 链接到 1 table 的所有外键。就像下面的例子。

exports.up = function (knex) {
  return knex.schema.createTable('Overview', (table) => {
    table.uuid('overview_id').primary()
    table
      .foreign('user_id')
      .references('user_id')
      .inTable('users')
      .onDelete('cascade')
    table
      .foreign('player_id')
      .references('player_id')
      .inTable('playerStats')
      .onDelete('cascade')
    table
      .foreign('registration_id')
      .references('registration_id')
      .inTable('registration')
      .onDelete('cascade')
    table
      .foreign('planet_id')
      .references('planet_id')
      .inTable('planetList')
      .onDelete('cascade')
    table
      .foreign('buildings_id')
      .references('buildings_id')
      .inTable('buildings')
      .onDelete('cascade')
    table
      .foreign('production_id')
      .references('production_id')
      .inTable('production')
      .onDelete('cascade')
    table
      .foreign('research_id')
      .references('research_id')
      .inTable('research')
      .onDelete('cascade')
    table
      .foreign('player_fleet_id')
      .references('player_fleet_id')
      .inTable('playerFleet')
      .onDelete('cascade')
    table
      .foreign('player_defense_id')
      .references('player_defense_id')
      .inTable('playerDefense')
      .onDelete('cascade')
  })
}
