Boolean Columns

Just found this little tidbit about returning a boolean from a tinyint column tonight on the rails wiki

Columns which are either boolean or tinyint(1) are recognised as booleans by ActiveRecord. So, if you have a table “people” and a column “rocks tinyint(1)”, you can say:

person = People.find(1)
person.rocks = true

However, person.rocks will return an integer, and Ruby thinks that 0 is true. If you want to test for truth, use person.rocks?, like this view example:

message = "You rock, dude!" if person.rocks?

I did not know that. Pretty dang cool.
