Extending model class causes Column not found error - php

Question

I'm using https://github.com/spatie/laravel-permission
I have created a new class which extends the Role class. Here is the code for Role:
<?php
namespace Spatie\Permission\Models;
use Illuminate\Database\Eloquent\Model;
use Spatie\Permission\Traits\HasPermissions;
use Spatie\Permission\Exceptions\RoleDoesNotExist;
use Spatie\Permission\Contracts\Role as RoleContract;
use Spatie\Permission\Traits\RefreshesPermissionCache;
class Role extends Model implements RoleContract
{
use HasPermissions;
use RefreshesPermissionCache;
/**
* The attributes that aren't mass assignable.
*
* #var array
*/
public $guarded = ['id'];
/**
* Create a new Eloquent model instance.
*
* #param array $attributes
*/
public function __construct(array $attributes = [])
{
parent::__construct($attributes);
$this->setTable(config('laravel-permission.table_names.roles'));
}
/**
* A role may be given various permissions.
*
* #return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function permissions()
{
return $this->belongsToMany(
config('laravel-permission.models.permission'),
config('laravel-permission.table_names.role_has_permissions')
);
}
/**
* A role may be assigned to various users.
*
* #return \Illuminate\Database\Eloquent\Relations\BelongsToMany
*/
public function users()
{
return $this->belongsToMany(
config('auth.model') ?: config('auth.providers.users.model'),
config('laravel-permission.table_names.user_has_roles')
);
}
/**
* Find a role by its name.
*
* #param string $name
*
* #throws RoleDoesNotExist
*
* #return Role
*/
public static function findByName($name)
{
$role = static::where('name', $name)->first();
if (! $role) {
throw new RoleDoesNotExist();
}
return $role;
}
/**
* Determine if the user may perform the given permission.
*
* #param string|Permission $permission
*
* #return bool
*/
public function hasPermissionTo($permission)
{
if (is_string($permission)) {
$permission = app(Permission::class)->findByName($permission);
}
return $this->permissions->contains('id', $permission->id);
}
}
My code was working fine when accessing this Role class directly for create()'s, but attempting to perform the same tasks using my new UserRole class, I am getting Column not found database errors when attempting to create a new Role.
Here is the UserRole class:
namespace App;
use Spatie\Activitylog\Traits\LogsActivity;
use Spatie\Permission\Models\Role;
class UserRole extends Role
{
use LogsActivity;
/**
* The attributes that should be logged.
*
* #var array
*/
protected static $logAttributes = ['name', 'permissions'];
}
So Role::create() works fine, but UserRole::create() does not.

Answer 1

Well changing the name to Role and then changing my use clause to as SpatieRole has fixed the issue. I'm guessing it was some type of class name relationship issue with Eloquent.

If you don't define the $table property on your Eloquent model, the table name is derived from the name of the Model. So, the Role model would use the roles table by default. The UserRole model would look for the user_roles table by default.
Since you still want to use the same table, but your model name is changed, you will need to define the $table property on your new model to make it look at the roles table.
class UserRole extends Role
{
protected $table = 'roles';
// ...
}
