Heroku - PGError：错误：“ENGINE”处或附近的语法错误

Question

我正在尝试

heroku rake db:migrate

在 Heroku 上运行我的迁移，前两次迁移运行得很好，但第三次迁移看起来像这样

create_table :charities, :options => "ENGINE=MyISAM" do |t|
  t.string :name,               :null => false
  t.string :title,              :null => false
  t.timestamps
end

add_index :charities, :name
add_index :charities, :title


Migrating to CreateCharitiesAndThemes (20091019140537)

-- create_table(:charities, {:options=>"ENGINE=MyISAM"})
rake aborted!
An error has occurred, this and all later migrations canceled:

Answer 1

Heroku 使用 PostgreSQL，而 MyISAM 引擎是 MySQL 特定的。我建议你删除那部分。或者，添加对使用的数据库的检查并将其设为可选。

这是如何检查数据库的链接< /a>.
