Contacts.cfc

Let's use CommandBox to build it:

coldbox create orm-entity entityName=contacts primaryKey=contactID properties=firstName,lastName,email --open

Then spice it up with the validation constraints

/**
* A cool Contact entity
*/
component persistent="true" table="contacts"{

    // Primary Key
    property name="contactID" fieldtype="id" column="contactID" generator="native" setter="false";

    // Properties
    property name="firstName" ormtype="string";
    property name="lastName" ormtype="string";
    property name="email" ormtype="string";

    // validation
    this.constraints = {
        firstName = {required=true},
        lastName = {required=true},
        email = {required=true, type="email"}
    };

}
