Rails error: ArgumentError in ArticlesController#create wrong number of arguments (2 for 1)

Question

我从这里获得了关于 Rails 的教程： Rails5

并想在表单中添加一个字段 "attachment"。 articles_controller.rb如下：

class ArticlesController < ApplicationController

http_basic_authenticate_with name: "gerrit", password: "Ifb6K54WVs7U", except: [:index, :show]

def index
  @articles = Article.all
end

def show
  @article = Article.find(params[:id])
end



def new
  @article = Article.new
end

def edit
  @article = Article.find(params[:id])
end

def create
  @article = Article.new(article_params)

  if @article.save
    redirect_to @article
  else
    render 'new'
  end
end

def update
  @article = Article.find(params[:id])

  if @article.update(article_params)
    redirect_to @article
  else
    render 'edit'
  end
end

def destroy
  @article = Article.find(params[:id])
  @article.destroy

  redirect_to articles_path
end

private
  def article_params
    params.require(:article).permit(:title, :text, :attachment)
  end
end

为此我添加了回形针和 turbolink5。

我重新运行了教程中的所有配置步骤，但我总是收到标题中的错误：

  Extracted source (around line #24):

def create
  @article = Article.new(article_params)

  if @article.save
    redirect_to @article

我在这里不使用单个参数，但是 article_params!? 感谢任何帮助！

如上条评论所述：

我将 paperclip 更新到 v5.1.0，错误消失了。
