Domain Object
Within any domain object you can define a public variable called this.constraints
that is a assigned an implicit structure of validation rules for any fields or properties in your object.
Declaration
component persistent="true"{
// Object properties
property name="id" fieldtype="id" generator="native" setter="false";
property name="fname";
property name="lname";
property name="email";
property name="username";
property name="password";
property name="age";
// Validation
this.constraints = {
// Constraints go here
}
}
We can then create the validation rules for the properties it will apply to it:
component persistent="true"{
...
// Validation
this.constraints = {
fname = { required = true },
lname = { required = true},
username = {required=true, size="6..10"},
password = {required=true, size="6..8"},
email = {required=true, type="email"},
age = {required=true, type="numeric", min=18}
};
}
That easy! You can just declare these validation rules and ColdBox will validate your properties according to the rules. In this case you can see that a password must be between 6 and 10 characters long, and it cannot be blank.
Usage
You can then use them implicitly when calling our validation methods:
validate( myUser );
validateOrFail( myUser );
