README

This package is an extension of Laravel Nova's existing BelongsTo field and Vue components.

Originally created by manmohanjit, the original package was abandoned.

Installation

You can install this package on a Laravel app that uses Nova via composer:

composer require webparking/nova-belongs-to-dependency

Usage

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

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

Look at the example below for other use cases.

Example

Database Structure

Type (id, name)
Posts (id, type_id, category_id, title, body)
Category (id, type_id, title)

We should only be able to assign categories to posts that belong to the same type.

This is how you would achieve it on the Nova category resource:

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

This would work if you used a text/enum type field too.

use Webparking\BelongsToDependency\BelongsToDependency;
...
return [
    ...
    Select::make('Type')->options([
        'post' => 'Post',
        'page' => 'Page',
    ])>displayUsingLabels(),
    
    BelongsToDependency::make('User')
        ->dependsOn('type', 'type'),
    ...
];
