Inspired from: https://github.com/Benjacho/belongs-to-many-field-nova The initial package did not work with older versions of Nova because of "sortableUriKey" Belongs To Many field to represent many to many relationship in field. This Field allow attaching relationships easily. Also you can:
composer require keops007/belongs-to-many-field
In the resource you need to pass:
use Keops007\BelongsToManyField\BelongsToManyField;
public function fields(Request $request){
return [
..., //If you are using with BelongsToMany native Field, put this field after
BelongsToManyField::make('Role Label', 'roles', 'App\Nova\Role'),
];
}
Function | Param | default | description |
---|---|---|---|
optionsLabel |
String | 'name' | If you don't have column 'name' in your relationship table, use this method. This displays in index and detail Ejm (optionsLabel('full_role_name') ). |
isAction |
Boolean | true | This method is when you need this field in actions, this puts height of field in 350px, and converts in action. |
setMultiselectProps |
Array | [] | this method allows you to set properties for the vue multiselect component |
dependsOn |
String, String | null, null | This method allows you to depend on belongsto field, this make an auto query |
canSelectAll |
String, Boolean | 'Select All', true | This method allows you to have a select all checkbox and display custom message |
IMPORTANT
use Keops007\BelongsToManyField\BelongsToManyField;
public function fields(Request $request){
BelongsToManyField::make('Role Label', 'roles', 'App\Nova\Role')->optionsLabel('full_role_name'),
}
public function handle(ActionFields $fields, Collection $models)
{
//note that roles is the many to many relationship function name
$values = array_column(json_decode(request()->roles, true),'id');
foreach ($models as $model) {
$model->roles()->sync($values);
}
}
BelongsToManyField::make('Role Label', 'roles', 'App\Nova\Role')
->options(\App\Role::all())
->setMultiselectProps([
'selectLabel' => 'click for select',
// and others from docs
]);
BelongsTo::make('Association', 'association', 'App\Nova\Association'),
BelongsToManyField::make('Participants', 'participant', 'App\Nova\Participant')
->dependsOn('association', 'association_id'),
BelongsToManyField::make('Participants', 'participant', 'App\Nova\Participant')
->canSelectAll('Seleccionar Todo'),
This package implement all Laravel Validations, you need to pass the rules in rules method, rules are listed on laravel validations rules for arrays*.
use Keops007\BelongsToManyField\BelongsToManyField;
public function fields(Request $request){
return [
...,
BelongsToManyField::make('Role Label', 'roles', 'App\Nova\Role')->relationModel(\App\User::class)->rules('required', 'min:1', 'max:5', 'size:3', new CustomRule),
];
}
For translations of this validations, use normal laravel validations translations.
