Belongs To Many create & edit form UI for Nova. Enables attaching relationships easily and includes validation.
Installation

Usage

public function fields(Request $request) { return [ AttachMany::make('Permissions'), ]; }
You can explicitly define the relationship & Nova resource:
AttachMany::make('Field Name', 'relationshipName', RelatedResource::class);
Pivot Values
You can pass additional parameters for any pivot value.
For details, please check https://laravel.com/docs/9.x/eloquent-relationships#syncing-associations
AttachMany::make('Field Name', 'relationshipName', RelatedResource::class, ['pivot_name' => value]);
Display on detail:
This package only provides the create / edit views that BelongsToMany does not.
BelongsToMany should be used for displaying the table on detail views.
public function fields(Request $request) { return [ AttachMany::make('Permissions'), BelongsToMany::make('Permissions'), ]; }
Validation
You can set min, max, size or custom rule objects
->rules('min:5', 'max:10', 'size:10', new CustomRule)

Relatable
The attachable resources will be filtered by relatableQuery() So you can filter which resources are able to be attached
Being Notified of Changes
You can add a method to the resource to be notified of the changes that have happened:
The method must be a camel cased version of the attribute name, followed by Synced
. For example:
public function fields(Request $request) { return [ AttachMany::make('Permissions'), ]; }
public function permissionsSynced(array $changes) { $changes['attached']; // An array of IDs of attached models $changes['detached']; // An array of IDs of detached models $changes['updated']; // An array of IDs of updated models }
Authorization
This field also respects policies: ie Role / Permission
- RolePolicy: attachAnyPermission($user, $role)
- RolePolicy: attachPermission($user, $role, $permission)
- PermissionPolicy: viewAny($user)
