Nullable database fields for the Laravel PHP Framework

Build Status Latest Stable Version Total Downloads License Buy us a tree

Often times, database fields that are not assigned values are defaulted to null. This is particularly important when creating records with foreign key constraints, where the relationship is not yet established.

public function up()
{
    Schema::create('profile_user', function (Blueprint $table) {
        $table->increments('id');
        $table->integer('user_id')->nullable()->default(null);
        $table->foreign('user_id')->references('users')->on('id'); 
        $table->string('twitter_profile')->nullable()->default(null);
        $table->string('facebook_profile')->nullable()->default(null);
        $table->string('linkedin_profile')->nullable()->default(null);
        $table->text('array_casted')->nullable()->default(null);
        $table->text('array_not_casted')->nullable()->default(null);
    });
}

More recent versions of MySQL will convert the value to an empty string if the field is not configured to allow null. Be aware that older versions may actually return an error.

Laravel does not currently support automatically setting nullable database fields as null when the value assigned to a given attribute is empty.

Installation

This trait is installed via Composer. To install, simply add it to your composer.json file:

$ composer require dyrynda/laravel-nullable-fields

In order to use this trait, import it in your Eloquent model, then set the protected $nullable property as an array of fields you would like to be saved as null when empty.

<?php

use Illuminate\Database\Eloquent\Model;
use Dyrynda\Database\Support\NullableFields;

class UserProfile extends Model
{
	use NullableFields;
	
	protected $nullable = [
		'facebook_profile',
		'twitter_profile',
		'linkedin_profile',
		'array_casted',
		'array_not_casted',
	];
	
	protected $casts = [ 'array_casted' => 'array', ];
	
}

Now, any time you are saving a UserProfile profile instance, any empty attributes that are set in the $nullable property will be saved as null.

<?php

$profile = new UserProfile::find(1);
$profile->facebook_profile = ' '; // Empty, saved as null
$profile->twitter_profile  = 'michaeldyrynda';
$profile->linkedin_profile = '';  // Empty, saved as null
$profile->array_casted = []; // Empty, saved as null
$profile->array_not_casted = []; // Empty, saved as null
$profile->save();
