Relation supports laravel accessors

[dhb52]

Relation::make('post.author')
                    ->title('Author')
                    ->fromModel(User::class, 'name')
                    ->required(),

It's better idea to support laravel Accessors

    public function getDisplayAttribute(): string
    {
        return $this->name . ' (' . $this->email . ')';
    }

Relation::make('post.author')
                    ->title('Author')
                    ->fromModel(User::class, 'display')
                    ->required(),

now relation xhr call returns

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'display' in 'where clause' (SQL: select * from `users` where `display` like %% limit 10)

Hey @dhb52, this works a little differently. Here's an excerpt from the documentation:

Selection options can work with calculated fields, but only to display the result, the search will occur only on one column in the database. To do this, use the displayAppend method.

namespace App;

use Illuminate\Database\Eloquent\Model;

class User extends Model
{
    /**
     * @return string
     */
    public function getFullAttribute(): string
    {
        return $this->attributes['name'] . ' (' . $this->attributes['email'] . ')';
    }
}

To indicate the displayed field you must:

Relation::make('users.')
    ->fromModel(User::class, 'name')
    ->displayAppend('full')
    ->multiple()
    ->title('Select users');

Thanks for solution, a subtle correctness for whom may check out this later.

Relation::make('post.author')  # better refactor column name to `author_id`
    ->fromModel(User::class, 'name')
    ->displayAppend('full')
    ->title('Select users');
