Hi Sirs.

An important trick on the famous ActiveRecord::Base find method.

When you are in development time of your application, and you do some query on your database query editor, is a good practice to use the limit clauses and selects just the columns you want.

In the find method we can do it with the :limit and :select arguments.

For example in our code when we try to authenticate some user we got it like:

find(:first, :conditions => [query, hash], :select => "id, email, login")

The returned object contains just the id, email and login attributes. Clean object.

Password and other attributes do not appears in the returned object =]

Simple development practice, but very important too.

See you.
