What''s the best way to handle a find that doesn''t find
anything?
For example.
Model Foo
@result = Foo.find(:first, :condition => "some condtion
string").name
if the condition is not met Foo.find stops the application with
''unexpected
nil''.
What is the best way to gracefully trap this error and return something
meaningfull to the calling method?
