OctoberCMS相关模型动态默认值

Question

I have a backend controller implements Backend\\Behaviors\\RelationController , I just want to set default values for the related model depending on the parent model values.

I have tried the following: model.beforeCreate , formExtendFields but no luck.

Thank you all.

After whole day of searching, I found the solution, it is documented no where on OctoberCMS website , I inspected the source file Backend\\Behaviors\\RelationController , after that I came with the below solution.

You should implement relationExtendViewWidget on your controller, then you can access the model from: $widget->model , something like below:

class Members extends Controller
{
    public $implement = [
        'Backend\Behaviors\RelationController',
    ];

    public function relationExtendViewWidget($widget, $field)
    {
        $member = Member::findOrFail($this->params[0]);

        $widget->model->course_id = $member->course_id;
        $widget->model->member_id = $member->id;
    }

    public function relationExtendManageWidget($widget, $field)
    {
        $member = Member::findOrFail($this->params[0]);

        $widget->model->course_id = $member->course_id;
        $widget->model->member_id = $member->id;
    }
}

I believe this should be documented somewhere on OctoberCMS documentation
