I was new to rails 7.0 as I followed the official guide in website, making the sample blog project.
When comes to the delete single post function. Seems my code still fires a GET HTTP request instead of a DELETE request. I only have one controller which is 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
My show.html.erb file was like:
<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>
UPDATE: my routes.rb was like
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
also when I perform bin/rails routes in terminal the output was like:

CodePudding user response：
In this part of code all seems to be okay. Can you show your routes.rb and all your routes? rails routes
After that we can step forward.
UPDATE
And where do you pass the :id param to delete article?
CodePudding user response：
Rails 7 is using hotwire and turbo instead of Rails/ujs.
So link_to have some problems, change link_to to button_to, it should work.
