我的rails应用程序有自己的
MySql数据库(并且需要MysqL2 gem),但也需要与一个特定模型的外部MongoDB数据库连接(因此我在Gemfile中包含了mongoid和bson_ext).现在,当我尝试为一个新的模型生成一个迁移时,它告诉我
$rails g migration CreateLocations
error mongoid [not found]
当我生成位置模型时,它包含了Mongoid :: Document,所以Rails显然认为它正在使用外部数据库作为主数据库.
databse.yml：
development: adapter: MysqL2 encoding: utf8 reconnect: false database: associalize_development pool: 5 username: root password: socket: /tmp/MysqL.sock
mongoid.yml：
development: host: pearl.mongohq.com port: 27019 username: asfasdf password: sadfasdf database: app4574678 test: host: pearl.mongohq.com port: 27019 username: asdfadhasdfa password: hadsadfas database: app4574678 production: host: pearl.mongohq.com port: 27019 username: asdfdfsasda password: afdasdfdasdf database: app4574678
UPDATE
使用Mongo的模型
class ExternalMongoModel
include Mongoid::Document
field :title
field :long_title
field :deal_type
field :merchandise_type
field :market_id
field :market_name
field :market_location,type: Array
field :featureType
field :country_code
field :subtitle
field :offer_ends_at
field :price
field :value
field :merchant_type
field :content
field :merchant
index(
[[:division_latlon,Mongo::GEO2D]],background: true
)
end
