Hi,

I have recently regenerated some old projects. In those I was using  
restful\_authentication and also now role\_requirement plugins.

In order to get those working I need to have some files in the lib  
folder, authenticated\_system.rb and role\_requirement\_system.rb  
respectively.

Installing the plugins didn’t add those files to the lib folder so I had  
to copy them manually.

But when those files are placed in that folder? When installing the  
plugin, or how? I mean, I guess that should happen automatically…

Thanks

If I recall correctly, that happens when you generate the authenticated  
user sessions (after the plugin is installed), as in:

ruby script/generate authenticated user sessions --include-activation

Thank you Ar Chron for the reply.

That explains it I believe.

Cheers
