Exception in Rails

Rails
1

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?
