Searchable Nova filter for belongsTo relationships.

This package is not needed with Nova 4, you can achieve the same behaviour with:

BelongsTo::make('User')
    ->searchable()
    ->filterable(),

This package assumes you have a text-search setup for your Eloquent models. See Laravel Scout.

composer require suenerds/nova-searchable-belongs-to-filter

For this example let's assume a user belongs to a department and a department has many users. To make the relationship searchable via a filter, add this to the filters() function of your Nova user resource:

By default the filter will display the name of the fieldAttribute you passed on instantiation. You can customize the name by passing it as an argument to the filter's construct function, for example my-new-name.

// app/Nova/User.php

use Suenerds\NovaSearchableBelongsToFilter\NovaSearchableBelongsToFilter

public function filters(Request $request)
{
    return [
	(new NovaSearchableBelongsToFilter('my-new-name'))
	    ->fieldAttribute('department')
	    ->filterBy('department_id')
    ];
}
