Unpermitted Parameter carrierwave

Question

I'm trying to upload a document within a nested form using the carrierwave gem. When I submit the form, I can see that there is an unpermitted parameter.

I have permitted the params in the controller

    def debt_params
  params.require(:debt).permit(:user_id, :amount, :commission, :invoice_issued, :invoice_date, :status, :details,
  document_attributes: [:id, :debt_id, :document],
  debtor_attributes: [:id, :user_id, :business_name, :abn, :first_name, :last_name, :email, :mobile_number, :phone_number],
  creditor_attributes: [:id, :user_id, :business_name, :abn, :first_name, :last_name, :email, :mobile_number, :phone_number])
end

The model accepts nested attributes for

class Debt < ActiveRecord::Base
 belongs_to :user
 belongs_to :creditor
 belongs_to :debtor
 has_many :documents

 accepts_nested_attributes_for :debtor
 accepts_nested_attributes_for :creditor
 accepts_nested_attributes_for :documents
end

Not sure what I'm missing here?

The answer was to change document_attributes to plural in the controller = documents_attributes
