Undefined property error in authentication

[abhivachan]

I am using laravel 5.3 and installed in Homestead. I have followed the below steps

1. Installed neo4j
2. Followed the steps Vinelab/NeoEloquent related configurations.
3. From laravel 5.3, I am able to connect to neo4j without any issues. I am able to create the user label with properties like (firstname, lastname, email, password etc.). Password is encrypted using bcrypt
4. No modification in Auth.php file.
5. Updated the method register in AppServiceProvider with the below line $this->app->bind(\Illuminate\Database\Eloquent\Model::class, \Vinelab\NeoEloquent\Eloquent\Model::class);
6. My Label details are below Label Name: User Data: { "firstname": "suresh", "isactive": "yes", "created_at": "2016-10-09 12:27:23", "middlename": "", "title": "suresh subramanian", "created_by": "ssuresh", "lastname": "subramanian", "password": "$2y$10$Ddr/y8LmVD6lvStB0dcj4OPlC.UjqC2CMjzozOkJ4kvXTNe1/isUi", "updated_at": "2016-10-09 12:27:23", "isadmin": "yes", "updated_by": "ssuresh", "name": "ssuresh", "email": "ssuresh@example.com" } ], "meta": [ { "id": 182, "type": "node", "deleted": false } ], "graph": { "nodes": [ { "id": "182", "labels": [ "User" ], "properties": { "firstname": "suresh", "isactive": "yes", "created_at": "2016-10-09 12:27:23", "middlename": "", "title": "suresh subramanian", "created_by": "ssuresh", "lastname": "subramanian", "password": "$2y$10$Ddr/y8LmVD6lvStB0dcj4OPlC.UjqC2CMjzozOkJ4kvXTNe1/isUi", "updated_at": "2016-10-09 12:27:23", "isadmin": "yes", "updated_by": "ssuresh", "name": "ssuresh", "email": "ssuresh@example.com" } } ], "relationships": [] } } ], "stats": { "contains_updates": false, "nodes_created": 0, "nodes_deleted": 0, "properties_set": 0, "relationships_created": 0, "relationship_deleted": 0, "labels_added": 0, "labels_removed": 0, "indexes_added": 0, "indexes_removed": 0, "constraints_added": 0, "constraints_removed": 0 } } ], "errors": [], "responseTime": 21 }

When I try to login with user id and password, the error is below

ErrorException in CypherGrammar.php line 99: Undefined property: Illuminate\Database\Query\Builder::$matches

I have further debugged the PHP code and getting error in

Type error: Argument 1 passed to Illuminate\Auth\EloquentUserProvider::validateCredentials() must be an instance of Illuminate\Contracts\Auth\Authenticatable, instance of Sample\NeoUser given, called in /home/vagrant/workbasket/php/projects/sample.dev/vendor/laravel/framework/src/Illuminate/Auth/SessionGuard.php on line 387

Can you post your User Model?

[abhivachan]

use Illuminate\Notifications\Notifiable;
use Illuminate\Foundation\Auth\User as Authenticatable;
use Vinelab\NeoEloquent\Eloquent;
use Vinelab\NeoEloquent\Facade\Neo4jSchema;

class NeoUser extends NeoEloquent
{
    protected $table = 'User';
    protected $connection = 'neo4j';
    protected $fillable = ['name','title','firstname','middlename','lastname','email','password','isadmin','isactive','created_by', 'updated_by'];
    public function createUser()
    {
        $user = NeoUser::create(
            [
                'name'  => 'ssuresh',
                'title' => 'suresh subramanian',
                'firstname' =>'suresh',
                'middlename'=>'',
                'lastname' => 'subramanian',
                'email'=>'ssuresh@example.com',
                'password' => bcrypt('password'),
                'isadmin' => 'yes',
                'isactive' => 'yes',
                'created_by' => 'ssuresh',
                'updated_by' => 'ssuresh'
            ]);
        $user->save();
    }
}

Any help will be really appreciated. :-)

[heydavid713]

Well the User is missing theimplements \Illuminate\Contracts\Auth\Authenticatable, \Illuminate\Contracts\Auth\CanResetPassword interfaces from the original Laravel User, they also work in NeoEloquent. Those are the ones that make Auth possible in Eloquent in general.

[abhivachan]

Thanks for your help . :-). I tried and getting another property error. array_filter() expects parameter 1 to be array, null given in Grammar.php line 812.

Is there example implementation will be really helpful?. I am not sure what I am really missing it.

My revised model is below.

class NeoUser extends NeoEloquent implements Authenticatable, CanResetPassword
{
    protected $table = 'User';
    protected $connection = 'neo4j';
    protected $fillable = ['name','title','firstname','middlename','lastname','email','password','isadmin','isactive','created_by', 'updated_by'];
    public function createUser()
    {
        $user = NeoUser::create(
            [
                'name'  => 'ssuresh',
                'title' => 'suresh subramanian',
                'firstname' =>'suresh',
                'middlename'=>'',
                'lastname' => 'subramanian',
                'email'=>'ssuresh@example.com',
                'password' => bcrypt('password'),
                'isadmin' => 'yes',
                'isactive' => 'yes',
                'created_by' => 'ssuresh',
                'updated_by' => 'ssuresh'
            ]);
        $user->save();
    }

It works. :-). It is implementation issue and not the framework issue. I am sorry for that.

[samirgit]

@abhivachan how did you make it work?

how did you implement Authenticatable when it is not an interface
