如何在 mongodb 中连接 2 个不同的主机
How to connect 2 different hosts in mongodb
我在 ruby 有一个服务,我试图连接两个不同的主机和两个不同的数据库
我正在尝试这样的事情
mongoid.yml
development:
clients:
default:
database: cpeTracking
hosts:
- development-shard.mongodb.net:27017
- development-shard.mongodb.net:27017
- development-shard.mongodb.net:27017
options:
user: my_user
password: my_password
auth_source: admin
ssl: true
database: testDb
hosts:
- localhost:27017
还有我的模特
class Movies
include Mongoid::Document
include Mongoid::Attributes::Dynamic
store_in database: "testDb"
field :name, type: String
field :year, type: Integer
field :director, type: String
end
当我运行服务时,只连接第一台主机。
我也试过这个解决方案
Connecting to two databases Mongoid 但没用
我找到了答案。
首先,我必须在相同的默认级别创建一个新客户端,我用数据库和主机的信息将其命名为 "secondary"。
development:
clients:
default:
database: my_db
hosts:
- development-shard.mongodb.net:27017
- development-shard.mongodb.net:27017
- development-shard.mongodb.net:27017
options:
user: my_user
password: my_pass
auth_source: admin
ssl: true
secondary:
database: testDb
hosts:
- localhost:27017
其次。在模型中,我必须添加集合、数据库和将使用
的客户端
class Movies
include Mongoid::Document
include Mongoid::Attributes::Dynamic
store_in collection: "movies", database: "testDb", client: "secondary"
field :name, type: String
field :year, type: Integer
field :director, type: String
end
