當我按照網站上的官方指南制作示例博客專案時，我是 rails 7.0 的新手。
當談到洗掉單個帖子功能時。似乎我的代碼仍然觸發 GET HTTP 請求而不是 DELETE 請求。我只有一個控制器是articles_controller.rb
class ArticlesController < ApplicationController
def index
@articles = Article.all
end
def show
@article = Article.find(params[:id])
end
def new
@article = Article.new
end
def create
@article = Article.new(article_params)
if @article.save
redirect_to @article
else
render :new, status: :unprocessable_entity
end
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, status: :unprocessable_entity
end
end
def destroy
@article = Article.find(params[:id])
@article.destroy
redirect_to root_path
end
private
def article_params
params.require(:article).permit(:title, :body)
end
end
我的 show.html.erb 檔案是這樣的：
<h1><%= @article.title %></h1>
<p><%= @article.body %></p>
<ul>
<li><%= link_to "Edit", edit_article_path(@article) %></li>
<li><%= link_to "Destroy", article_path(@article),
method: :delete,
data: { confirm: "Are you sure?" } %></li>
</ul>
更新：我的 routes.rb 就像
Rails.application.routes.draw do
root "articles#index"
resources :articles
# Define your application routes per the DSL in https://guides.rubyonrails.org/routing.html
# Defines the root path route ("/")
# root "articles#index"
end
當我 bin/rails routes在終端執行時，輸出也像：
Prefix Verb URI Pattern Controller#Action
root GET / articles#index
articles GET /articles(.:format) articles#index
POST /articles(.:format) articles#create
new_article GET /articles/new(.:format) articles#new

uj5u.com熱心網友回復：
Rails 7 使用 hotwire 和 turbo 代替 Rails/ujs。所以的link_to有一些問題，改變link_to到button_to，它應該作業。
