When upgrading Laravel from 5.4 to 5.5 I got the following error:

Call to undefined method Webpatser\\Uuid\\UuidFacade::generate()

I'm using 'Uuid' => Webpatser\Uuid\Uuid::class, in my aliases.

My code:

static::creating(function ($model) {
     $model->{$model->getKeyName()} = Uuid::generate()->string;
});

I needed to be able to validate UUIDs on a Laravel API I'm creating, but couldn't find a solution in Laravel itself. Here's my attempt to create a ServiceProvider that introduces the validation support (it also fixes #5).

I wouldn't consider this PR complete, however, because it lacks the localization support. Whenever the user does happen to run across a UUID that is invalid, it only says validation.uuid as the message instead of something friendlier.

I spent some time looking through the Laravel documentation trying to find a way for packages to add non-namespaced localization (or configure the validator to use the namespaced localization key), but it doesn't seem like that's currently possible.

As I was finalizing the pull request, I noticed that this library also supports MAC-address-like UUIDs (those are considered UUIDs?). I'm not sure the regex I use in the validation function is robust enough to handle validating something like that, so feel free to replace the regex in that with something else.

I also updated the README with instructions on how to activate the service provider and how to configure the localization on the application's Laravel instance (because like I said above, it doesn't seem like we can configure it in the package for the time being).

I like to know in which type of situation I need to use this program. Can you give me some real time scenarios.. which will be easy for me to understand..

Hi,

While using the findOrFail(id) method, I noticed that Eloquent returns a record matching a different id than the one I pass in. It does not throw an error, so it took me some time to find this flaw.

Am I correct to assume that findOrFail() is currently not supported by this package?

Kind regards,

Sander

Hey, I wanted to use this for my API, and after running composer require, I tried to use the library in my code, but was unsuccessfull.

It seems like Lumen does not know anything about it.

Help please?

Hey,

I have three entities: 'items', 'users', and 'cities'. Users can receive items in certain cities and I want to save where a particular user has received that item. As I could have millions of items in the database, I don't want to use integer ids, so I figured I'd use your uuids like so

Schema::create('items', function (Blueprint $table) {
            $table->uuid('id');
            $table->string('name');
            $table->timestamps();
            $table->primary('id');
        });

Schema::create('item_user', function (Blueprint $table) {
            $table->increments('id');
            $table->uuid('item_id')->references('id')->on('items');
            $table->integer('user_id')->references('id')->on('users');
            $table->integer('city_id')->nullable();
            $table->timestamps();
        });

Schema::create('cities', function (Blueprint $table) {
            $table->increments('id');
            $table->integer('country_id');
            $table->string('englName');
            $table->string('nativeName');
            $table->timestamps();
        });

and added the following lines in the Item Model class

public static function boot()
  {
    parent::boot();
    self::creating(function ($model) {
        $model->id = (string) Uuid::generate(4);
    });
  }
    public function users(){
      return $this->belongsToMany('App\User');
    }

    public function cities(){
      return $this->belongsToMany('App\City', 'item_user');

However the relationships weren't returning anything even though I filled the database with legitimate testing data. So I started investigating and just put a var_dump on all queries using \DB::connection()->enableQueryLog(); and {{var_dump(DB::getQueryLog())}} finding that the binding for those queries goes wrong. As you can see it uses some integer value even though it should be using the uuid. Do you have any ideas what is going wrong?

[3]=> array(3) { ["query"]=> string(283) "select "users".*, "item_user"."item_id" as "pivot_ item_id", "item_user"."user_id" as "pivot_user_id" from "users" inner join "item_user" on "users"."id" = "item_user"."user_id" where "item_user"."item_id" in (?)" ["bindings"]=> array(1) { [0]=> int(1) } 

`

Whoops, looks like something went wrong.

1/1 FatalErrorException in PhotosController.php line 40: Class 'App\Http\Controllers\Uuid' not found``

added it to aliasses...

Using UUID via a trait:

` <?php

namespace App;

use Webpatser\Uuid\Uuid;
trait Uuids
{

    /**
     * Boot function from laravel.
     */
    protected static function boot()
    {
        parent::boot();

        static::creating(function ($model) {
            $model->{$model->getKeyName()} = Uuid::generate()->string;
        });
    }
}`

When creating a record, the uuid is stored in the database uppercase, but it is passed to the return route url in lowercase. When you click on the same record from a list view the url contains the uuid in uppercase. I did not think this was an issue until trying to use Laravel Scout and Algolia Search.

This causes Algolia to create two records in the index, one with a lower case uuid when the record is created and another with uppercase uuid when the record is modified. Only the uppercase uuid is searchable since it matches the database record.

Why is this happening and how can I force uppercase UUID only within the trait?

When I want return UUID that generated in the JSON, laravel return this error. I use utf8_encode function like this return utf8_encode(Webpatser\Uuid\Uuid::generate()); and error fixed. after saved UUID in the database and get it, the value is correct and did not generate error anymore. laravel 5.5

I have created a trait and applied it to my model. But in other side, How to solve the problem of making uuid in many to many relationship, where we do not make model many to many table?

Example : we have two model User and Role and we have three tables users , roles and user_role. we have sync code bellow. $create = $user->roles()->sync($roles_id); we get $create with id = '' how to solve the problem?

Hey!

I use laravel-uuid in my project and I found a problem with routing. I store UUIDs in uuid column and I have also this code in user model:

// app/User.php

/**
 * Get the route key for the model.
 *
 * @return string
 */
public function getRouteKeyName()
{
    return 'uuid';
}

When I send GET request (for example to http://127.0.0.1:8000/api/v1/users/5af0ed93-5575-4c91-951c-f4b065ea2aea) I get an error:

SQLSTATE[42S22]: Column not found: 1054 Unknown column 'id' in 'where clause' (SQL: select * from `users` where `id` = 1 limit 1)

My router:

// routes/api.php

Route::prefix('v1')->middleware(['auth:api'])->group(function () {
    Route::resource('users', 'UserController', ['only' => ['update', 'show', 'destroy']]);
});

In the readme the minimum php version listed for 4.* is 7.3 but in the composer.json it has 7.0. dependabot is raising a pr for this when the project php version is 7.2 and it's passing. Either the readme should be updated or the composer.json file

I've been troubleshooting parts our our application and came across uuid's that I believe do not have their RFC4122 version information.

Uuid::generate( 4 )->string

Example: 14326a6c-184f-11ea-9e97-06aad2cae86c

A version 4 UUID is defined in RFC 4122: 128 randomly-generated bits with six bits at certain positions set to particular values. the four most significant bits of the 7th byte to 0100'B, so the high nibble is "4" set the two most significant bits of the 9th byte to 10'B, so the high nibble will be one of "8", "9", "A", or "B"

https://www.cryptosys.net/pki/uuid-rfc4122.html https://tools.ietf.org/html/rfc4122#section-4.1.3

I have a high load on one of my apps right now. I've never seen this error:

Integrity constraint violation: 1062 Duplicate entry '' for key 'PRIMARY'

Should I be worried about NULL collisions as records are being inserted?

Thanks, btw! I love the package.

Validate-function returns true with parameter value "20191015_100_051". The result is the same with any given parameter of length 16. Tested with version 3 on Laravel 5.5.
