I have model named Test\_session and am trying to add data to it. I have  
always been in the situation where I have the user fill out a form and  
then create a new entry in a table. This time I am trying to save  
sessions of a test where the session has the users id and group they  
belong to. I tried doing the following…

@test\_session = Test\_session.new() or Test\_session.new \<— I tried  
them both  
@test\_session.user\_id = session[:user\_id]  
@test\_session.group = session[:group]  
@test\_session.save

I get the following error…

Expected /app/models/test\_session.rb to define Test\_session

Like i said normally I use something on the lines of… @test\_session =  
Test\_session.new(params[:test\_session]) where the params comes from a  
form. How can you create a new entry in the database without a form and  
then set the two fields based of of two values stored in a session

The file does exists and the .rb files for a few other models are also  
empty and they work fine… although the entried are filled out through  
a form

Thanks a lot… my naming was wrong. The file is called test\_session.rb  
but when you open the file the class is TestSession. I always thought  
it was good to use \_ in ruby. Maybe just the wrong case here.

Ideally you shouldn’t have underscores in class names anyway; They  
should  
always be CamelCase.

Can you show us the code from test\_session.rb? At a guess it’s  
TestSession  
and not Test\_session.
