    Bonjour à tous.
    Je suis en train de la gestion des utilisateurs, et je reçois quelques erreurs que 'ai tenté de regler mais vainement.
    l'erreur suivante s'affiche si je veux creer un utilisateur "Call to undefined method App\User::assignRole()"
    et celle ci quand je veux editer un utilisateur "Call to undefined relationship [roles] on model [App\User]"


    Ceci est le code du modele Role
    <?php

    namespace App;

    use Illuminate\Database\Eloquent\Model;
    use Spatie\Activitylog\Traits\LogsActivity;

    class Role extends Model
    {
    use LogsActivity;

    /
    The attributes that are mass assignable.

    @var array
    /
    protected $fillable = ['name', 'label'];

    /

    A role may be given various permissions.

    @return \Illuminate\Database\Eloquent\Relations\BelongsToMany
    /
    public function permissions()
    {
    return $this->belongsToMany(Permission::class);
    }

    /
    Grant the given permission to a role.

    @param Permission $permission

    @return mixed
    /
    public function givePermissionTo(Permission $permission)
    {
    return $this->permissions()->save($permission);
    }

    /

    Change activity log event description

    @param string $eventName

    @return string
    /
    public function getDescriptionForEvent($eventName)
    {
    return CLASS . " model has been {$eventName}";
    }
    }

    Ceci est le code du modele User

    <?php

    namespace App;

    use Illuminate\Notifications\Notifiable;
    use Illuminate\Contracts\Auth\MustVerifyEmail;
    use Illuminate\Foundation\Auth\User as Authenticatable;

    class User extends Authenticatable
    {
    use Notifiable;

    /
    The attributes that are mass assignable.

    @var array
    /
    protected $fillable = [
    'name', 'email', 'password',
    ];

    /

    The attributes that should be hidden for arrays.

    @var array
    /
    protected $hidden = [
    'password', 'remember_token',
    ];

    Salut,

    Il me semble que le trait n'est pas définit dans le modèle User :

    class User extends Authenticatable
    {
    use HasRoles;

Vous ne pouvez pas répondre à ce sujet.
