For example: I create an object c. Now, if I call c.xxx, ruby just raise an exception 'method missing' But, I want it return nil, for each method which is not pre-defined. Is there a way I can gain this ? Thanks!
If you are doing something like this s = c.xxx then u can always give recue nil which would then set the value of s as nil.
Thank you!~ I imaged there may be some trigger, open it, then object of some class will response to every method. close it, then exception raises. I wanna the classes predefined by ruby/rails can have this functionality. Can anyone tell me how to diy it ? For example, I want a model class has this kind of trigger.
Then I think yo need to write your custom method_missing in you model class. This is how rails actually creates its dynamic finders by invoking method_missing in base.rb. Or you can actually modify the method_missing in base.rb as per your need.
Thank very much! That's just I want. I lack of knowledge about how rails works, I think. Thanks a lot!!
