Question

在开发模式下一切正常，但是当我尝试在生产模式下启动我的应用程序（RAILS_ENV =生产脚本/服务器）时，我收到以下错误：

/opt/ruby1.8/lib/ruby/gems/1.8/gems/searchlogic-2.4.19/lib/searchlogic/named_scopes/conditions.rb:81:in `method_missing': protected method `scope' called for #<Class:0x7f41de524410> (NoMethodError)

        from .../app/models/comment.rb:2:in `include'                                                           
        from .../app/models/comment.rb:2                                                                        
        from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `gem_original_require'                                          
        from /opt/ruby1.8/lib/ruby/site_ruby/1.8/rubygems/custom_require.rb:31:in `require'...

现在在我看来，acts_as_commentable gem导致了这一点。但是，为什么它在开发模式下工作正常。

Answer 1

在开发模式类中，您可以根据需要加载它们。在生产中，它们在轨道启动时被缓存。

Answer 2

由于fl00r的评论，我发现了错误：

显示comment.rb（第2行）

comment.rb中的第2行是include ActsAsCommentable::Comment。这对我来说有点奇怪，所以我看了一下acts_as_commentable gem的官方文档。那就是问题所在。应该是acts_as_commentable。必须从某个地方复制粘贴它。

尽管如此，神秘仍然是它如何在开发模式中发挥作用。由于annaswims提到的类缓存？

Ruby on Rails应用程序无法在生产模式下启动
