Rails - May 2011 - How to placing common exceptions for all models in single method?

Hi guys,

In my models i am using common exception in every methods.

So Instead of writing same exception code on each method  of model is
there a best way to separate exception code into seperate method.

when we need it simple we need to invoke that method.


for example like this

def rescue_excetpion
 begin

  rescue => e
   raise  "Error message is #{e}"

  end

end

so when i invoke this rescue_excetpion method in my events method

it need to apply

def events
rescue_excetpion
@user = User.find(1)
end


Any one have idea about this ?

 How to move all common exceptions into a single method ?

 How to invoke that method?

Thanks in advance !!

Sounds like your rescue_exception method should be yielding to a block, you can
then do
rescue_exception do
  ...
end

If you want to handle these exceptions at the controller level, you might want
to look at rescue_from
