Yeah,
I think you just want to overwrite it for the specific connection 
adapter.
Do "ActiveRecord::Base.connection.class",

reopen that class,
and redefine quote on that class.

See also alias_method_chain if you want to overwrite but still call 
through to the original function

Indeed Freddy,

Although I quite like doing my aliases as "blah_before_blah" and 
"blah_after_blah"
rather than with / without.
but...

Hi,

The theory I ve understood...
Unfortunelty,  ive got no idea how to actually do it.

I ve tried the following:
I ve created a quoting.rb in my rails app lib folder.
module ActiveRecord
  module ConnectionAdapters # :nodoc:
    module Quoting
      def quote(value, column = nil)
        my new code...


Afterwards I ve added a require of my little quoting file into my
environment file... well, but that does not work
So, you mentioned that just reopen the class and ...
How do I actually do that?

Hi,

Ok, after some further try and errors...
I ve achieved what I want with the following code:
module ActiveRecord
  module ConnectionAdapters # :nodoc:
    class AbstractAdapter
      # Quotes the column value to help prevent
      # {SQL injection attacks}[http://en.wikipedia.org/wiki/
SQL_injection].
      def quote(value, column = nil)

As suggested, I ve tried this time to overwrite the AbstractAdapter
class and not the quoting module.

Thanks a lot.

hmm...
well I tried overwriting the Quoting module,
and it works.
>> module ActiveRecord::ConnectionAdapters::Quoting
>> def quote(value, column=nil)

so perhaps you were doing something else wrong.
