Ruby on rails Rake迁移找不到表

因此，我在db->migrate文件夹中创建了一个手动文件名001_create_users.rb，如下所示：

class CreateUsers < ActiveRecord::Base
  def self.up
    create_table :users do |t|
      t.string :name
      t.string :email
      t.string :password
      t.string :bio

      t.timestamps
    end
  end

  def self.down
    drop_table :users
  end
end

---

您是从

ActiveRecord:：Base

继承的，而它应该是

ActiveRecord:：Migration

class CreateProjects < ActiveRecord::Migration
  def change
    create_table :projects do |t|
      t.text :title
      t.text :description
      t.text :slug

      t.timestamps
    end
  end
end

class CreateProject

class CreateProjects < ActiveRecord::Migration
  def change
    create_table :projects do |t|
      t.text :title
      t.text :description
      t.text :slug

      t.timestamps
    end
  end
end
