LoadError：无法自动加载常量

Question

I have a model called Conversation in app/models/conversation.rb and a class called Messages::Conversation in app/lib/messages/conversation.rb . When I try to call Conversation from console (expecting to get the model) it returns:

[1] pry(main)> Conversation
    LoadError: Unable to autoload constant Conversation, expected .../application/app/lib/messages/conversation.rb to define it
    [2] pry(main)> Messages::Conversation
    => Messages::Conversation

I also have a model/class called Message similar to the above Conversation . Since I am namespacing these, why is still looking for Conversation in my Messages::Conversation file instead of just Conversation in app/models ?

Does it have something to do with having a messages folder and Message model? If I rename app/lib/messages/... to app/lib/messages_test/... , everything works as expected.

Before

# config/application.rb
config.autoload_paths += Dir["#{config.root}/lib/**/"]

After

# config/application.rb
config.autoload_paths += Dir["#{config.root}/app/models/"]
config.autoload_paths += Dir["#{config.root}/lib/**/"]

Check your config/application.rb and see if it works when you make these adjustments. Not 100% sure if it will work.
