Rails : uninitialized constant

Question

I have a model called class App::BaseModel into a file called base_model.rb

Then I have a message.rb file which on the first line has the following:

class App::Message < App::BaseModel

When starting the server I get the error:

/path/to/app/message.rb:1:in `<top (required)>': uninitialized constant App::BaseModel (NameError)

Can someone help me with this please?

Cheers

It's on `/path/to/app/app/models/my_app_name/`, the weird thing is that I was able to get this to work on a Mac but not on a Linux. — Telmo Gonçalves, Apr 25 '13 at 11:05

for base_model.rb it should be => class BaseModel WebActivity < ActiveRecord::Base

and for message.rb it should be => class Message < ActiveRecord::Base

The problem is that I'm using a ActiveRecord made by hand, I'm not using the default Rails ActiveRecord. – Telmo Gonçalves Apr 25 '13 at 11:03

Rails have a naming convention, so if would like to put your model into App module (App::BaseModel), you should put the base_model.rb into app dir inside your models directory. Then Rails will load your file and class in it in a right way.

I'm sorry, I have the files into `/path/to/app/app/models/my_app_name/` – Telmo Gonçalves Apr 25 '13 at 11:04
