Alright, what you would want is to use is a named scope, that way you can have other scopes in the future. Usually you want to stay away from changing the default scope because it would affect other queries.

The code below creates a named scope called current_account and it ensures that all records match the condition, the account_id of the record must match the current account_id.

named_scope :current_account, :conditions => { :account_id => account_id }

Then when you want to use the named_scope you can call the code below:

User.current_account.all

This is just like calling:

User.all(:conditions => { :account_id => account_id })

Hope this helps you, let me know if anything is confusing.
