Unpermitted parameter: :phone_number. Context: { controller: OrdersController, action: create, request: #<ActionDispatch::Request:0x00007f54ac186660>

Question

I created a form with custom routing for orders with resources :orders , only: [:new, :create] and i want the users to click the submit button and the form fields should save the data into database, but when i click submit button, inside of the terminal it shows unpermitted params can anyone point out the mistake what i am doing in order for it to save into database

orders_controller.rb

class OrdersController < ApplicationController

    # GET to /orders/new
    def new
        @order = Order.new
    end

    # POST to /orders
    def create
        @order = Order.new(order_params)
        if @order.save
            redirect_to root_path, notice: "Order saved"
            
        else
            redirect_to root_path, notice: "Error Occured"
        end



    end

    private
        def order_params
            params.require(:order).permit(:paper_size, :color, :quantity, :type, :description, :first_name, :last_name, :phone_numnber, :email, files: [] )
        end
end

Answer 1

You typed phone_numnber, not phone_number.
