README

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

Installation

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

composer require manmohanjit/nova-belongs-to-dependency

Usage

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

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