Toggle Behavior

A CakePHP behavior to handle unique toggles.

An implementation of a unique field toggle per table or scope. This will ensure that on a set of records only one can be a "toggled" one, setting the others to false then. On delete it will give the toggle status to another record if applicable.

Usage

Basic usage

Include behavior in your Table class as

$this->addBehavior('Tools.Toggle', [
    'field' => 'primary', 
    'scopeFields' => ['user_id'],
    'scope' => [],
]);

Set the field to your table field. Optionally, you can also set scope fields and a manual scope. Those will always be taken into consideration as scope conditions.

Configuration

The 'findOrder' can be used to further customize the find result when looking for a new toggle record. By default it will try to use the modified field as DESC. But maybe you would want it to sort by another field.
