Octobercms: How can I make a repeater field jsonable because I am creating this repeater field into a different plugin

Question

How can I make a repeater field jsonable because I am creating this repeater field into a different plugin and I have created my own plugin. for example: I want to add a repeater field in rainlab.user plugin model but I want to do this by my own plugin so updates on rainlab.user plugin won't affect my work. Thanks

You should read about Extending Plugins.

1) First register the events in your custom plugin.php - Example

2) Add the related fields to your migration file - Example - Make sure the field type is set to json or text : $table->json('field_name')->nullable();

Let's say you want to add a Dogs repeater field to the User Model ;

public function boot()
{

    UserModel::extend(function($model)
    {
        $model->addJsonable([
            'dogs',
        ]);
    });

    UsersController::extendFormFields(function($form, $model, $context){

        if (!$model instanceof UserModel) {
            return;
        }

        $form->addTabFields([
            'dogs' => [
                'label'      => 'My Dogs',
                'type'       => 'repeater',
                'form'       => [
                    'fields' => [
                        'breed' => [
                            'label' => 'Breed',
                            'type' => 'dropdown',
                            'options' => [
                                'labrador' => "Labrador",
                                'cocker'   => "Cocker Spaniel"
                            ]
                        ],
                        'name' => [
                            'label' => 'Name',
                            'type' => 'text',
                        ]
                    ],
                ],
            ],
        ]);

    });

}
