Hello,

So I installed the restful\_authenticaiton plugin on an empty rails 2.3.4 project.

$ script/plugin install restful\_authentication

Generated files using "Students" as my model (instead of the often- used "Users"). Note that I've added the --include-activation flag.

$ ./script/generate authenticated students sessions --include- activation

And after editing my environment.rb with the line: config.active\_record.observers = :student\_observer # or whatever you

I get the following output when trying to run script/server

$ ./script/server =\> Booting WEBrick =\> Rails 2.3.4 application starting on [http://0.0.0.0:3000](http://0.0.0.0:3000) /Library/Ruby/Gems/1.8/gems/ activesupport-2.3.4/lib/active\_support/dependencies.rb:443:in load\_missing\_constant': uninitialized constant StudentObserver (NameError)

What step might I have missed to get this error?

If you specify :student\_observer your "script/generate" should be:

script/generate authenticated student sessions --include-activation

NOTE: student not students
