使用 Yaml 进行 MongoMapper 配置

发布于 2024-12-11 19:08:09 字数 410 浏览 1 评论 0原文

我有我的 Yaml 配置文件 mongo.yml：

development:
  adapter: mongodb
  database: fhsclock_development
  host: localhost
  port: nil

test:
  adapter: mongodb
  database: fhsclock_test
  host: localhost
  port: nil

production:
  adapter: mongodb
  database: fhsclock
  hosts:
  - - localhost
    - nil
  - - staff.mongohq.com
    - 10015

如何使用此文件进行配置并与 MongoMapper 连接？

I have my Yaml configuration file, mongo.yml:

development:
  adapter: mongodb
  database: fhsclock_development
  host: localhost
  port: nil

test:
  adapter: mongodb
  database: fhsclock_test
  host: localhost
  port: nil

production:
  adapter: mongodb
  database: fhsclock
  hosts:
  - - localhost
    - nil
  - - staff.mongohq.com
    - 10015

How do I use this file for configuration and connection with MongoMapper?

如果您正在使用 Rails 并且该文件位于 config/mongo.yml，MongoMapper 将仅使用该文件。如果您不在 Rails 上，则可以改编此代码来自源头：

config_file = Rails.root.join('config/mongo.yml')
if config_file.file?
  config = YAML.load(ERB.new(config_file.read).result)
  MongoMapper.setup(config, Rails.env, :logger => Rails.logger)
end

此外，“适配器”你的文件是无关的。（请参阅入门文档）。来自 rails g mongo_mapper:config 的 mongo.yml 如下所示：

defaults: &defaults
  host: 127.0.0.1
  port: 27017

development:
  <<: *defaults
  database: my_app_development

test:
  <<: *defaults
  database: my_app_test

# set these environment variables on your prod server
production:
  <<: *defaults
  database: my_app
  username: <%= ENV['MONGO_USERNAME'] %>
  password: <%= ENV['MONGO_PASSWORD'] %>

MongoMapper will just use the file if it's you're using Rails and the file is at config/mongo.yml. If you're not on Rails, you can adapt this code from the source:

config_file = Rails.root.join('config/mongo.yml')
if config_file.file?
  config = YAML.load(ERB.new(config_file.read).result)
  MongoMapper.setup(config, Rails.env, :logger => Rails.logger)
end

Also, the "adapter" in your file is extraneous. (See the Getting Started documentation). A mongo.yml from rails g mongo_mapper:config looks like:

defaults: &defaults
  host: 127.0.0.1
  port: 27017

development:
  <<: *defaults
  database: my_app_development

test:
  <<: *defaults
  database: my_app_test

# set these environment variables on your prod server
production:
  <<: *defaults
  database: my_app
  username: <%= ENV['MONGO_USERNAME'] %>
  password: <%= ENV['MONGO_PASSWORD'] %>
