Some validations are provided:
-
Presence (not empty):
User::validates("name" ,array("presence"=>true)) -
Regular expression:
User::validates("email",array("format" =>"^[_a-z0-9-]+(\.[_a-z0-9-]+)*@[a-z0-9-]+(\.[a-z0-9-]+)*(\.[a-z]{2,4})$"))There are options to allow blank and null values:"allow_blank"=>trueand"allow_null"=>true, after the "format" option likeUser::validates("zip",array("format"=>"^[0-9]{5}-[0-9]{3}$","allow_null"=>true)) -
Uniqueness:
User::validates("email",array("uniqueness"=>true)) -
Numericality:

You can check for an valid object using $user->isValid().
For multiple validations on the same attribute, just add a validates line for each validation.
