使用 Yaml 进行 MongoMapper 配置 [英] Use Yaml for MongoMapper Config

问题描述

我有我的 Yaml 配置文件，mongo.yml:

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

如何使用此文件进行配置和与 MongoMapper 的连接?

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

推荐答案

MongoMapper 只会使用该文件，前提是您使用的是 Rails 并且该文件位于 config/mongo.yml.如果你不在 Rails 上，你可以适应 this codenoreferr从源头:

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

此外，您文件中的适配器"是无关紧要的.(请参阅入门文档).来自 rails g mongo_mapper:config 的 mongo.yml 看起来像:

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'] %>
