Heroku - PGError:错误:"ENGINE"处或附近的语法错误

Question

我想跑

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,MyISAM引擎是特定于MySQL的.我建议你删除那部分.或者,添加检查使用的数据库并使其成为可选项.

这是一个如何检查数据库的链接.
