I'm new to Rails, so I'll preface this by saying that I might be
wrong, but you can give it a shot. I believe you have to have a
"begin" and "rescue" within your methods, not surrounding them as you
illustrated above. So your authenticate method might look like this:
def authenticate (name, args)
begin
#the first two arguments are always username and password
generic_login(args[0], args[1])
unless logged_in?
raise Exceptions::LoginFailedError , "LoginFailedError:
Invalid user name or password"
end
rescue Exception => e
n = e.exception "#{e.inspect}: #{e.message}"
n.set_backtrace []
raise n
end
end
Since you'll probably have multiple methods that require error
handling, I think you can define an error handling method outside of
each of your other methods. Instead of processing the exception
separately within each method's rescue function, your rescue functions
would instead call the error handling method. See below. Not 100%
sure this is kosher, but it's worth a shot...and let me know if it
works, I'm going to be building error handling into my app fairly
soon :)
def method_1
begin
#code
rescue Exception => e
process_exception(e)
end
end
def process_exception(e)
#code for handling exception
end
end
