Installation

This package can be installed via command:

composer require aqjw/nova-belongs-to-dependency

Usage

The following will list categories with type_id equal to the value set in the first BelongsTo field.

use Aqjw\BelongsToDependency\BelongsToDependency;
...
return [
    ...
    BelongsTo::make('Type'),
    
    BelongsToDependency::make('User')
        ->dependsOn('type', 'type_id')
    ...
];

Methods

dependsOn

The method can take one or two parameters. If you don't pass the second parameter, it will be generated from first one with the _id suffix.

This may depend on BelognsTo, Text, Enum, and others 🤷

BelongsToDependency::make('User')
    ->dependsOn('type', 'type_id'),

Multiple dependency

You can also pass an array as the first parameter. To make a dependency on two or more fields.

BelongsToDependency::make('User')
    ->dependsOn(['type', 'role']),

Or

BelongsToDependency::make('User')
    ->dependsOn([
        'type' => 'type_id',
        'role' => 'role_id',
    ]),

searchable

Use this method if you have many entries.

BelongsTo::make('Country')
    ->searchable(),

BelongsToDependency::make('State')
    ->searchable()
    ->dependsOn('country'),

BelongsToDependency::make('City')
    ->searchable()
    ->dependsOn('state'),

buildQuery

If you want to add your own conditions to the query then greet the buildQuery method.

BelongsToDependency::make('Product')
    ->dependsOn('category')
    ->buildQuery(function ($query, $values) {
        $query->where($values)
            ->where('status', 'active');
    }),

formatResource

Use this method to change the resource format. This can be useful if you want to group items.

BelongsToDependency::make('Product')
    ->dependsOn('category')
    ->formatResource(function ($resource) {
        return [
            'display' => $resource->name,
            'value' => $resource->id,
            'group' => $resource->parent_category,
        ];
    })
