I’m having a little problem figuring out how to stub this scenario:

my controller has this code in it:

if current\_user.foos \<\< @foo

and my spec is giving me errors about a missing stub:

Mock ‘foos’ received unexpected message :\<\< with

Also related to this issue, I’m using mock\_model but it’s not pulling  
in the methods from the model I’ve specified and I have to specify  
every single stub that I want to use. Is this normal behavior?

Anyway, I also tried to do

@user = mock\_model(User)  
@user.foos.stub!(:\<\<).and\_return([])

which still gave me the same dreadful error. Can anyone assist me with  
my two problems?

TIA
