Overview

The ObjectifiedSessionGenerator is what gets invoked when you run rails generate objectified_session. It looks at whatever you have set as your ObjectifiedSessions class (which, of course, is overwhelmingly going to be the default at this point, since users likely won’t have changed/customized it before they run this), and then plunks a file under lib/, in the right place, with an empty class, with nice comments in it.

I can't currently load that class, but there's already a file at the following path:

#{target_file.inspect}

Please check that file to see what class it contains; if it's incorrect, remove it, and try again.}
