I'm very new with Laravel and Laravel backpack. I have installed yesterday the demo version and I'm trying to create my first crud.

My crud will consist of 6 dependent select database dropdowns and one field.

I have disabled 6 of my fields to test with only one select dropdown 'product_type_id'.

I have created according to the documentation :

database tables
models
Controller
Route
Menu Item

When I'm loading my CRUD, my CRUD is loaded, but I get this error : 'Error Loading Page. Please refresh the page'. Whit the Chrome Inspect function, I can see that there's an error generated by Search POST :

"message": "Call to undefined relationship [product_type] on model [AppModelsMageProduct]."

Whatever I'm trying, I always get this error. I'm certainly missing something, so I would appreciate some help here. I have of course read the related other similar issues concerning undefined relationships on StackOverflow, but couldn't solve it by myself. Please find hereafter my models and controller. Thanks in advance for your support, cheers, Marc
