It continues with the same error. I have created with a scaffold a  
posts\_controller:

class PostsController \< ApplicationController  
rescue\_from Activerecord::NoMethodError. with =\> :not\_found

protected  
def not\_found  
Code  
end

end

But it gives me the same error when I go to some view: NoMethod error.  
What’s is it wrong?

You’ve got several typos in here. What’s actually in your posts  
controller?  
In addition NoMethodError sounds like a bad thing to be rescuing like  
this. What’s the real problem you’re trying to solve?

For example, considerar I have an object named product. This product has  
a price. If I destroy that product and go to a ticket index view  
(showinng ID, client name and product) I get NoMethodError with  
ticket.product.price. Of course, if I don’t destroy that product, I  
don’t get that error.

Yeah I’ve often lamented the fact that we need a “halt dot-method  
chain” in ruby.

Oh dear god!

def show  
@product = Product.find(params[:id])  
rescue ActiveRecord::RecordNotFound  
not\_found  
end

protected

def not\_found  
your\_code\_here  
end

Is it really that hard?
