问题
So this question came about because of this other question I was looking into.
So I have dabbled in this a bit working with backend forms and thought I knew how to tackle this. However I am not seeing the results that I thought I would. I have tried to do some research and haven't seen anyone bring this up in the issues on the github page or here in stackoverflow. Unless I missed it. How do you show the stored extra Pivot Data in the backend?
Here is my model.php
relationship:
public $belongsToMany = [
'equipments' => [
'Brandon\Pixelrpg\Models\Equipments',
'table' => 'brandon_pixelrpg_equipment_inventory',
'key' => 'inventory',
'otherKey' => 'equipment'
]
];
Here is my controller.php
:
public $implement = [
'Backend\Behaviors\ListController',
'Backend\Behaviors\FormController',
'Backend\Behaviors\ReorderController',
'Backend\Behaviors\RelationController'
];
public $listConfig = 'config_list.yaml';
public $formConfig = 'config_form.yaml';
public $reorderConfig = 'config_reorder.yaml';
public $relationConfig = 'config_relation.yaml';
Here is my config_relation.yaml
:
equipments:
label: Equipments
view:
list:
columns:
id:
label: ID
type: number
searchable: true
sortable: true
name:
label: Name
type: text
searchable: true
sortable: true
value:
label: Value
type: number
searchable: true
sortable: true
updated_at:
label: Updated
type: datetime
searchable: true
sortable: true
pivot[quantity]:
label: Quantity
type: number
pivot:
form:
fields:
pivot[quantity]:
label: Quantity
type: number
default: 0
So here is my backend form showing correctly the relation manager. You will noticed that the quantity field is not being filled out. In the second image of my database it does correctly get filled out updated and deleted using the form:

So I solved this after digging around and reading laravel documents. The solution was to add pivot => ['quantity']
in the model relationship configuration.
public $belongsToMany = [
'equipments' => [
'Brandon\Pixelrpg\Models\Equipments',
'table' => 'brandon_pixelrpg_equipment_inventory',
'key' => 'inventory',
'otherKey' => 'equipment',
'pivot' => ['quantity']
]
];
