Ruby 在ActiveRecord中迁移和设定数据种子时，外键约束失败

我们正在尝试将数据迁移到Ruby中的sqlite3数据库中，其中包含3个类之间的类关联

class Artist < ActiveRecord::Base
    has_many :events
    has_many :venues, :through => :events
end

每个迁移文件都是这样的

Event.create(id: 2599084, venue_id: 82166, playdate: "2015-06-06", name: "U2 at Pepsi Center", artist_id: "5039")
Venue.create(id: 81533, name: "Paradise Theatre", cityid: "2055", state: "CO", city: "Paonia", zip: "80246")
Artist.create(id: 5039, artistname: "U2", genre: "Pop / Rock")

class CreateEventsTable < ActiveRecord::Migration[6.0]
  def change
    create_table :events do |t|
      #table and column to reference (join)
      t.string :name
      t.date :playdate
      t.references :artist, foreign_key: true
      t.references :venue, foreign_key: true
    end
  end
end

class CreateEventsTable

class CreateVenuesTable

class CreateArtistsTable

为了拥有每一个

-活动参考：艺术家和场地

-场地参考了许多活动和艺术家

-艺术家引用了许多事件

我们的结果是：
