Hi,

I’m developing an engine with a controller, and I have problems to  
configure the routing.  
The engine is located in vendor/plugins/web\_file\_attachment. Under  
that directory:

- the controller is in app/controllers/web\_file\_attachments.rb

- I’m trying with this controller classes:  
class WebFileAttachment::WebFileAttachmentsController \<  
ApplicationController  
and I have tried with equivalent configurations for class  
WebFileAttachmentsController \< ApplicationController

- in routes.rb, I have this (following the docs stating that the  
plugin name is the first part of the controller name):  
connect “/app/web\_file\_attachments/:action/:id”, :controller =\>  
“web\_file\_attachment/web\_file\_attachments”

And in the main rails config/routes.rb I have this:  
map.from\_plugin :web\_file\_attachment

I still end with this error:  
uninitialized constant  
WebFileAttachment::WebFileAttachmentsController

though this is exactly how I name my controller.  
If I try  
require ‘web\_file\_attachments’  
in init.rb, I get an error with ApplicationController not defined.

What am I doing wrong here?  
I’m using rails 2.1.1 and engines 2.0.0

Thanks in advance.

Raphaël

The most obvious things are:

- if your controller is  
WebFileAttachment::WebFileAttachmentsController, then it should be in  
a file called vendor/plugins/web\_file\_attachment/app/controllers/  
web\_file\_attachment/web\_file\_attachments\_controller.rb
- if your controller is WebFileAttachmentsController, then it should  
be in a file called vendor/plugins/web\_file\_attachment/app/controllers/  
web\_file\_attachments\_controller.rb

Essentially - the name of the plugin isn’t involved in namespacing the  
controller, and the file needs to end with \_controller.rb. Hopefully  
that should get you back on track.

Thanks,

James

Maybe the documentation could be a bit clearer? The example at  
[http://api.rails-engines.org/classes/Engines/RailsExtensions/Routing.html](http://api.rails-engines.org/classes/Engines/RailsExtensions/Routing.html)  
puts ‘my\_pluign/’ in the controller route.

yes, you’re right, I misnamed the controller file. Thanks for pointing  
it out!

You’re absolutely right - that is confusing. I’ll change that to make  
it clearer.

Thanks!
