在 controllers 中定义 destory 方法
然后在 index 视图中加入 Destroy 链接
[root@h202 blog]# vim app/controllers/articles_controller.rb
[root@h202 blog]# cat app/controllers/articles_controller.rb
class ArticlesController < ApplicationController
def new
@article = Article.new
end
def edit
@article = Article.find(params[:id])
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
def create
# render plain: params[:article].inspect
# @article = Article.new(params[:article])
@article = Article.new(article_params)
if @article.save
redirect_to @article
else
render 'new'
end
end
def show
@article = Article.find(params[:id])
end
def index
@articles = Article.all
end
private
def article_params
params.require(:article).permit(:title,:text)
end
end
[root@h202 blog]# vim app/views/articles/index.html.erb
[root@h202 blog]# cat app/views/articles/index.html.erb
<h1>Link test!!!!</h1>
<%= link_to 'My Blog', controller: 'articles' %>
<%= link_to 'New article', new_article_path %>
