Rgeo,Mysql和Spatial索引错误

Question

在尝试运行迁移以添加空间索引时,请获取

Unknown key: spatial/Users/ME/.rvm/gems/ruby-2.0.0-p353/gems/activesupport-4.0.2/lib/active_support/core_ext/hash/keys.rb:70:in `block in assert_valid_keys'

运用

• Ruby 2.0.353
• Rails 4.0.2
• RGEO 0.3.20
• RGEO活跃记录0.4.6
• 项目清单
• activerecord-mysql2spatial-adapter 0.4.3

迁移索引文件看起来像

class CreateAddresses < ActiveRecord::Migration
  def change
    create_table :addresses, :options => 'ENGINE=MyISAM' do |t|
      t.string :street_1
      t.string :street2
      t.string :city
      t.string :state
      t.string :zip
      t.string :country
      t.string :full_address
      t.column :latlon, :point, :null => false

      t.timestamps
    end
    add_index :addresses, :latlon, :spatial => true
  end
end

UPDATE

当我将database.yml文件中的适配器从mysql2更改为mysql2spatial时,更正了此错误和其他错误
