Ruby Wrapper Class results in NameError uninitialized constant

Question

I'm trying to model some UI elements.

I've created a series of classes in /app/models/wrappers/*

For this post i'm going to focus on a class called InputTextVO

I have:

class InputTextVO
...
end

/app/models/wrappers/InputTextVO.rb

When I try and initialize it in my controller I get the following:

NameError in InputsController#index
uninitialized constant InputsController::InputTextVO

@ivo = InputTextVO.new

RubyMine can locate the class and doesn't report any errors in my controller.

Try `@ivo = ::InputTextVO.new`. I thought that everything in `app/models` was already in the autoload path... — Robin, May 06 '14 at 18:24
also you should name the file correctly in snake case e.g. `input_text_vo.rb` — engineersmnky, May 06 '14 at 18:27

You must to add a module if you want to create a subdirectory in the model directory. You can do it like this :

class Wrappers::InputTextVO
...
end
Wrappers::InputTextVO.new #....

It should work.

You can also create a new directory like this app/wrapper.
