adding automatic conditions to find method

Hello,

Is there a way to add automatic condition to all active record find
methods?

I have an attribute in all my tables something like "effective_end_date"
so that I don't delete records but I keep them by setting
effective_end_date so I want to put condition is all my find queries
effective_end_date Is null or effective_end_date > Time.now. I don't
want to type this for every single query so I was wondering if it's
possible to automate it.

Thanks,

Tam

Yes, you can use default_scope: http://api.rubyonrails.org/classes/ActiveRecord/Base.html#M002258
It supports the same options as the find methods.
