我从这里有Rails教程: Rails5
并希望在表单中添加字段“附件”。 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。
我重新运行教程中的所有配置步骤,但我总是在标题中收到错误:
Extracted source (around line #24):
def create
@article = Article.new(article_params)
if @article.save
redirect_to @article
我这里不使用单个参数,但是article_params!? 任何帮助表示赞赏!
答案 0 :(得分:0)
正如上一篇评论所说:
我将回形针更新到v5.1.0,错误消失了。
