Define labels

Label can store in a static property of model, or in a locale file. Labels in locale files will override model's static property

1. Define labels in model class

Define a static property named $labels, it is an array of labels, with key is fields name, value is label. Label maybe a string or callable value. If it's a callable value, then result of it will used as label, that callable has 1 argument, it is the field need to get label.

class Country extends Model
{
    use SoftDeletes, LabelFieldTrait;
    
    //...
    
    public static $labels = [
        'name' => 'Name of country',
        'flag' => function($field){
            return 'Flag ('.$field.')';
    }];
    
    //...

2. Define labels in locale files

Add file to site's locale folder, named model_<model_name_in_snake_case>.php. This locale file return an array of string. Labels of model's fields store at a key named is field, it is an array of field name and label.

<?php
return [
    'field' => [
        'name' => 'Tên quốc gia'
    ]
];
