Hello,

I wanted to convert an Engine (in casu the RikiEngine) into namespaces,  
to avoid naming clashes. I did this as I thought it should be done: I  
created in the view, model and controller directory seperate riki\_engine  
directories, and renamed the classes to for instance

class RikiEngine::LibraryController \< ApplicationController

Everything seems to work, but until I try to access a method which is  
defined in the riki\_engine directory under lib (the  
riki\_engine\_helper.rb). In there things are defined as:

module RikiEngine  
def foo  
end  
end

When I call foo from a controller method, or from within a view, it is  
unknown, whereas previously, there was no problem. So obviously there is  
a namespace problem here. I tried several things, without success.  
Mainly because I don’t get the bottom line of namespace yet. Can  
somebody shed a light on this problem, if only the solution?

And related to this problem, what is the opinion on putting engines  
immediately in their own namespace? Don’t get me wrong, I don’t mind  
doing it manually, and I can imagine that automating this might be more  
difficult, in comparison to the two minutes of doing it manually.

Thanks!

Bart

It’s very unlikely that there will ever be any kind of ‘automatic  
namespacing’ provided with by the Engines plugin; less magic and  
behaviour which is consistent with the rest of Rails is always  
preferable.
