Heroku rake任务未初始化为MongoMapper模型的常量 [英] Heroku rake task uninitialized constant for MongoMapper model

问题描述

我有一个很小的rake任务，只是将一个新的延迟作业插入队列中。我插入了一行调试行

  desc'开始处理新的rss feed文章'
 task：process_new_articles => ：environment do 
 config = RSS_CONFIG 
 feeds = config ['rss_feeds'] 
 
把Article.all 
 
 feeds.each do | feed | 
 Delayed :: Job.enqueue ProcessNewArticlesJob.new（feed，config ['settings']）
 end 
 end 
  

它似乎正确加载配置信息。但是，在运行任务时，我收到未初始化的恒定文章错误。文章是一个MongoMapper模型。我已经验证了与数据库的连接（在MongoLab上）工作正常。

这一切在本地都很有效。

更奇怪的是，引用Article.all使用heroku run console工作得很好。

堆栈跟踪不会显示太多：

  2011-12-04T22：33：02 + 00：00 app [start.1]：rake aborted！ 
 2011-12-04T22：33：02 + 00：00 app [start.1]：未初始化的常量Article 
  

<

我不小心命名了我的文章模型文件，

Article.rb，并且大写字母为A.这导致Heroku在运行rake environment时没有采用它。

奇怪而且很可能是一个bug？

I have a tiny rake task which just sticks a new delayed job into the queue. I've inserted a debug line

desc 'Start processing new rss feed articles'
    task :process_new_articles => :environment do
    config = RSS_CONFIG
    feeds = config['rss_feeds']

    puts Article.all

    feeds.each do |feed|
       Delayed::Job.enqueue ProcessNewArticlesJob.new(feed, config['settings'])
    end
end

It seems to be loading the config info correctly. But I'm getting a "uninitialized constant Article" error upon running the task. Article is a MongoMapper model. I've verified the connection to the database (on MongoLab) works fine.

This all works great locally.

What is even more bizarre is that referencing Article.all using "heroku run console" works just fine.

The stack trace doesn't show much:

2011-12-04T22:33:02+00:00 app[start.1]: rake aborted!
2011-12-04T22:33:02+00:00 app[start.1]: uninitialized constant Article

解决方案

Found the problem and it is totally weird.

I had accidentally named my Article model file, "Article.rb" with a capital A. This caused Heroku to not pick up on it upon running "rake environment".

Strange and most likely a bug?
