How do I add custom field in 'roles' table on guard 'web'?

[jahid404]

Hi,
I have added a new field named salary in roles table using new migration add_salary_to_roles_table with following code:

public function up(): void
{
    Schema::table('roles', function (Blueprint $table) {
        $table->string('salary')->after('short_name')->default(0)->nullable();
    });
}

Here is the current structure of roles table:

Note: I have added a new field named short_name before. But, there was no problem with web guard.

It has been created a new field salary on roles table. But, when I try to create a role with necessary data, it returns an error like: 'There is no permission named salary for guard web'.
Here is the controller code:

foreach ($request->all() as $key => $value) {
    if ($key != '_token' && $key != 'role_name' && $key != 'short_name' && substr($key, -7) != '_module') {
        $permissions[] = $key;
    }
}

// create role
$role = Role::create([
    'name' => $request->role_name,
    'short_name' => $request->short_name,
    'salary' => $request->salary
]);

// give requested permissions to role
foreach ($permissions as $item) {
    $role->givePermissionTo($item);
}

In here, Role is creating perfectly with salary value, but problem is occuring when trying to give permissions to the Role.
Help me please...
