Sorry guys i miss ":" next to the new in the controller

class TodoItemsController < ApplicationController
  def index
    @todo_list = TodoList.find(params[:todo_list_id])
  end

  def new
    @todo_list = TodoList.find(params[:todo_list_id])
    @todo_item = @todo_list.todo_items.new
  end


  def create
    @todo_list = TodoList.find(params[:todo_list_id])
    @todo_item = @todo_list.todo_items.new(todo_item_params)

    if @todo_item.save
        flash[:success] = "Added todo list item."
        redirect_to todo_list_todo_items_path
    else
        flash[:error] = "There was a problem adding that todo list item."
        render action: :new
    end
  end

  private
  def todo_item_params
    params[:todo_item].permit(:content)
  end

end
