Class ModelValidators

java.lang.Object
  com.scooterframework.common.validation.Validators
      com.scooterframework.orm.activerecord.ModelValidators

public class ModelValidators
extends Validators

ModelValidators contains validation methods to validate a model record.

Subclass of ActiveRecord may override one or more of the following methods in order to use validations:

• validatesRecord() (applies to create, update, and save a record)
• validatesRecordBeforeCreate() (applies to create a record)
• validatesRecordBeforeUpdate() (applies to update a record)
• validatesRecordBeforeSave() (applies to save a record)
• validatesRecordBeforeDelete() (applies to delete a record)

To use a different ModelValidators class, subclass of ActiveRecord must override validators() method.

 Examples:
      public class Post extends ActiveRecord {
            public void registerRelations() {
                belongsTo(Topic.class, "mapping: topic_id=id; counter_cache: true");
                belongsTo(User.class, "mapping: user_id=id; counter_cache: true");
            }

            public void validatesRecord() {
                validators().validatesPresenceOf("body");
                validators().validatesLengthMaximum("body", 10000);
            }
        }
