Hi all,

I have some issues when a link is clicked twice quickly that deletes  
an ActiveRecord row.

All I really want to do is set up some universal catch that will  
redirect all application errors to index.

Best way?

Thanks!

Shawn

in your ApplicationController, define:

def rescue\_action(exception)  
super # optional

# your code

end

try this:  
instead of ActiveRecord::Errors use ActiveRecord::ActiveRecordError,

class ApplicationController \< ActionController::Base

rescue\_from ActiveRecord::ActiveRecordError, :with =\> :method\_name

private

def method\_name  
redirect\_to your\_path  
end

Put a redirect tag in 404.html or 500.html, perhaps.
