Strong parameters definition issue

Question

Employee controller has the following definition for params. Positions attribute seems init correctly.

def employee_params
  params.fetch(:employee, {}).permit(
    :note,
    positions_attributes: [:id, :branch_id , :department_id, :employee_id],
    :work_type)
end

The error I am getting is the following:

Answer 1

If you want to put not enclosed in {} hash, it's only possible if this is the last parameter of the method. This is not the case in your example, so you should change your code a little bit:

def employee_params
  params.fetch(:employee, {}).permit(:note, :work_type,
                                     positions_attributes: [:id, :branch_id , :department_id, :employee_id])
end
