Rails控制器不接受Rails教程中的参数

Question

i'm trying to create a new controller, i'm following the getting started tutorial. I've renamed articles to investments for something different. I keep getting the following error relating to my controller

myapp/app/controllers/investments_controller.rb:20: syntax error, unexpected ')', expecting keyword_end

The controller looks like this:

class InvestmentsController < ApplicationController

def show
@investment = Investment.new(params.require(:investment).permit(:title, :text))
end

def new
end

def create
    @investment = Investment.new

    @investment.save
    redirect_to @investment
end


private
  def investment_params
    params.require(:investment).permit(:title, :description))
  end
end

I've also added extra strings to the database. Adding them to the params didn't seem to work either

您在行尾有双括号

 params.require(:investment).permit(:title, :description))
