Of course! Remember, this is just Ruby. Put something like this in
spec/spec_helper.rb:
####################
module InspectModelForRSpec
def inspect
...
end
end
ActiveRecord::Base.send(:include, InspectModelForRSpec)
####################
Now, as long as the code is not inadvertently loading up
spec/spec_helper.rb when running the app or console, you'll only see
the result of this when you run specs.
