第一次调用控制器，定义了常量，第二次调用，“未初始化的常量Oauth"? [英] First Call to a Controller, Constant is defined, Second call, "uninitialized constant Oauth"?

问题描述

我正在尝试使OAuth gem与Rails 3一起使用，并且遇到了这个奇怪的问题...(与gem无关，我想我以前也曾遇到过此问题)

I am trying to get the OAuth gem to work with Rails 3 and I'm running into this weird problem... (independent of the gem, I think I've run into this once before)

我有一个名为"OauthTestController"的控制器和一个名为"ConsumerToken"的模型.该模型如下所示.

I have a controller called "OauthTestController", and a model called "ConsumerToken". The model looks like this.

require 'oauth/models/consumers/token'
class ConsumerToken < ActiveRecord::Base
  include Oauth::Models::Consumers::Token
end

当我转到"/oauth_test/twitter"时，它会加载Oauth::Models::Consumers::Token模块，并且我可以毫无问题地连接到twitter.但是第二次尝试(只是刷新/oauth_test/twitter网址)，它给了我这个错误:

When I go to "/oauth_test/twitter", it loads the Oauth::Models::Consumers::Token module and I'm able to connect to twitter no problem. But the second time I try it (just refresh the /oauth_test/twitter url), it gives me this error:

NameError (uninitialized constant Oauth):
  app/models/consumer_token.rb:4
  app/models/twitter_token.rb:2
  app/controllers/oauth_test_controller.rb:66:in `load_consumer'

那是为什么?它与加载路径或处于开发模式有关吗?

Why is that? It has something to do with load paths or being in development mode maybe?

推荐答案

尝试使用require_or_load而不是require.每次开发时都会强制执行全部负载，有时可以帮助解决此类问题.

Try using require_or_load instead of require. That forces full load each time when in development and can sometimes help with this sort of issue.
