Mongoid 3 + Heroku（MongoHQ）导致Moped :: Errors :: OperationFailure [英] Mongoid 3 + Heroku (MongoHQ) cause Moped::Errors::OperationFailure

问题描述

使用Rails 3，从Mongoid 2.x升级到Mongoid 3.x后，我的Heroku + MongoHQ设置停止工作。有趣的是，我的发展&测试框架和我的整个测试套件都很好。

我怀疑问题在于我的mongoid.yml文件，但我试过搜索文档，google& stackoverflow，并使用了所有建议的格式，包括： heroku mongohq和mongoid Mongo :: ConnectionFailure 或实际上是这样的： https://gist.github.com/2900804

7月16日更新：这是我的mongoid.yml文件在多次尝试后的样子+ 在MongoHQ的Jason建议之后：

 开发：
会话：
默认值：
数据库：开发
主机：
  -  localhost：27017 
 
测试：
会话：
默认值：
数据库：测试
主机：
  -  localhost ：27017 
 
生产：
会话：
默认值：
 uri：<％= ENV ['MONGOHQ_URL']％> 
选项：
 skip_version_check：true 
 safe：true 
  

（根据我的理解，它基本上与上面的链接中的一样，只是它使用了uri;我尝试了另一种方式，将MONGOHQ_URL拆分为单独的字段，但它没有帮助）

我尝试将mongoid设置为3.0.0rc，并将版本留在我的Gemfile中。使用github版本由于HTTPS证书或其他原因而失败，所以我没有多次尝试它。

动作控制器说的是这样的：

  Moped :: Errors :: OperationFailure in Home＃index 
 
显示/ app / app / views / home / index .html.haml在第2行出现的位置：
 
操作：＃< Moped :: Protocol :: Command 
 @ length = 68 
 @ request_id = 4 
 @ response_to = 0 
 @ op_code = 2004 
 @flags = [：slave_ok] 
 @full_collection_name =。$ cmd
 @ skip = 0 
 @limit = -1 
 @selector = {：count =>：posts，：query => {}} 
 @ fields = nil> 
失败，出现错误db assertion failure
  

当我运行时

  heroku run console 
  

我得到这个：

我想我已经搜索了一切，运行多个github mongoid问题，多次阅读文档。 ..我在这里没有什么想法了。

任何想到的东西我都应该尝试下一步？

解决方案

您将需要使用Ruby 1.9.3。请参阅Mongoid文档此处和Heroku文档 here 关于如何使用1.9.3。

我也遇到类似的错误，并且我改变了我的gemfile以包含 ruby​​'1.9.3'，并且所有事情都按预期工作。

编辑：
@herb指出你需要最新版本的打包工具才能工作（ gem install bundler --pre ） 。否则，Gemfile中的 ruby​​'1.9.3'将不起作用。

With Rails 3, after upgrading from Mongoid 2.x to Mongoid 3.x, my Heroku + MongoHQ setup stopped working. Funny thing is, that my development & test frameworks and my whole test suite passes just fine.

I suspect the problem is with my mongoid.yml file, but I've tried searching the docs, google & stackoverflow, and used all the suggested formats, including this: heroku mongohq and mongoid Mongo::ConnectionFailure or actually this: https://gist.github.com/2900804

UPDATED July 16th: This is how my mongoid.yml file looks, after trying multiple things + After what Jason from MongoHQ suggested:

development:
  sessions:
    default:
      database: development
      hosts:
        - localhost:27017

test:
  sessions:
    default:
      database: test
      hosts:
        - localhost:27017

production:
  sessions:
    default:
      uri: <%= ENV['MONGOHQ_URL'] %>
      options:
        skip_version_check: true
        safe: true

(to my understanding, it is essentially the same as the one in the links above, except that it uses the uri; I tried the other way, splitting the MONGOHQ_URL into the separate fields as well, but it didn't help)

I've tried setting mongoid as 3.0.0rc and leaving the version blank in my Gemfile. Using the github version failed due to HTTPS certificates or something, so I didn't bother trying it multiple times.

What the action controller says is this:

Moped::Errors::OperationFailure in Home#index

Showing /app/app/views/home/index.html.haml where line #2 raised:

The operation: #<Moped::Protocol::Command
  @length=68
  @request_id=4
  @response_to=0
  @op_code=2004
  @flags=[:slave_ok]
  @full_collection_name=".$cmd"
  @skip=0
  @limit=-1
  @selector={:count=>:posts, :query=>{}}
  @fields=nil>
failed with error "db assertion failure"

and when I run

heroku run console 

.. I get this:

I think I've googled everything, run through multiple github mongoid issues, read the documentation multiple times ... and I'm running out of ideas here.

Anything come to mind I should try next?

UPDATE 2 July 16th: did as Jason & MrKurt said (first forgot to run bundle update mongoid, but that didn't help either). Now the error changed, though:

NoMethodError in Home#index

Showing /app/app/views/home/index.html.haml where line #2 raised:

undefined method `[]' for nil:NilClass

Extracted source (around line #2):

解决方案

You will need to use Ruby 1.9.3. See Mongoid documentation here and Heroku documentation here on how to use 1.9.3.

I was also getting similar errors, and I changed my gemfile to include ruby '1.9.3' and everything worked as expected again.

Edit: @herb pointed out that you need the latest version of bundler for this to work (gem install bundler --pre). Otherwise, ruby '1.9.3' in your Gemfile will not work.

这篇关于Mongoid 3 + Heroku（MongoHQ）导致Moped :: Errors :: OperationFailure的文章就介绍到这了，希望我们推荐的答案对大家有所帮助，也希望大家多多支持IT屋！
