/**
 * ExistValidator validates that the attribute value exists in a table.
 *
 * ExistValidator checks if the value being validated can be found in the table column specified by
 * the ActiveRecord class [[targetClass]] and the attribute [[targetAttribute]].
 * Since version 2.0.14 you can use more convenient attribute [[targetRelation]]
 *
 * This validator is often used to verify that a foreign key contains a value
 * that can be found in the foreign table.
 *
 * The following are examples of validation rules using this validator:
 *
 * ```php
 * // a1 needs to exist
 * ['a1', 'exist']
 * // a1 needs to exist, but its value will use a2 to check for the existence
 * ['a1', 'exist', 'targetAttribute' => 'a2']
 * // a1 and a2 need to exist together, and they both will receive error message
 * [['a1', 'a2'], 'exist', 'targetAttribute' => ['a1', 'a2']]
 * // a1 and a2 need to exist together, only a1 will receive error message
 * ['a1', 'exist', 'targetAttribute' => ['a1', 'a2']]
 * // a1 needs to exist by checking the existence of both a2 and a3 (using a1 value)
 * ['a1', 'exist', 'targetAttribute' => ['a2', 'a1' => 'a3']]
 * // type_id needs to exist in the column "id" in the table defined in ProductType class
 * ['type_id', 'exist', 'targetClass' => ProductType::class, 'targetAttribute' => ['type_id' => 'id']],
 * // the same as the previous, but using already defined relation "type"
 * ['type_id', 'exist', 'targetRelation' => 'type'],
 * ```
