Rails 控制台和 mongodb
我有一个关于 Rails 和 mongodb 的小问题。我有一个小应用程序，在开发模式下运行得很好。它也可以在生产模式下工作，但是当我进入 Rails 控制台时，我看不到其中的任何内容。
user-001@marcus:/var/www/webapp% rails c RAILS_ENV="production"
You did not specify how you would like Rails to report deprecation notices for your RAILS_ENV=production environment, please set config.active_support.deprecation to :log, :notify or :stderr at config/environments/RAILS_ENV=production.rb
Loading RAILS_ENV=production environment (Rails 3.2.1)
1.9.3p0 :001 > User.all
=> []
我的 config/initialize/mongo.rb 看起来像这样
MongoMapper.connection = Mongo::Connection.new('localhost', 27017)
MongoMapper.database = "webapp-#{Rails.env}"
if defined?(PhusionPassenger)
PhusionPassenger.on_event(:starting_worker_process) do |forked|
MongoMapper.connection.connect if forked
end
end
，但它看起来也很空
$ mongo localhost:27017/mail1up-production
MongoDB shell version: 1.8.2
Fri Feb 17 18:26:00 *** warning: spider monkey build without utf8 support. consider rebuilding with utf8 support
connecting to: localhost:27017/webapp-production
> db.mycollection.stats()
{ "errmsg" : "ns not found", "ok" : 0 }

我做错了什么吗？为什么看不到数据库中的数据？我该如何测试它？
I have a small issue with Rails and mongodb. I have a small app which works great in development mode. It also works in production mode, but when I enter the rails console I can't see anything in it.

Am I doing something wrong? Why can't I see the data in the database? How can I test it?

我认为这可能与您的查询语法有关。我刚刚遇到了同样的问题，我尝试使用普通的 ActiveRecord 查询。我使用 MongoDB 和 Mongoid 作为我的 ORM。
另一个问题与您的问题相关，尽管它也使用 Mongoid：
mongoid-finders-not-working
我发现使用以下“全部”查询成功：
User.all.to_aI think it may be related to your query syntax. I just ran into the same thing where I attempted to use the normal ActiveRecord queries. I'm using MongoDB with Mongoid as my ORM.
This other question is related to yours, although it too is using Mongoid:
mongoid-finders-not-working
I found success using the following for an "all" query:
User.all.to_a看来您需要运行
mmconsole。然后，您将被放入包含 MongoMapper 的 irb 中，并且您的数据库设置为“mm-test”。
在您的情况下，您的 mongo.rb 初始值设定项可能不受尊重，并且您连接到 mm-test 数据库而不是“webapp-#{Rails.env}”。
我在此处获得了一些信息
It seems like you need to run
mmconsole.You will then be dropped into irb with MongoMapper included and your database set to ‘mm-test’.
In your situation it may be that your mongo.rb initializer isn't respected and that you are connected to the mm-test database instead of "webapp-#{Rails.env}".
I got some of this information here
