路由错误没有路由匹配[GET]“/products/1”

Question

I'm practicing with RoR with a CRUD, but when I want delete some product, I got this error (like in the image), I don't know why got this error, someone can help me pleas?

This is my routes.rb

Rails.application.routes.draw do
  
  get '/products', to: 'products#index'
  get '/products/new', to: 'products#new'
  post '/products', to: 'products#create'
  post '/products/:id', to: 'products#shows', as: 'product'
  get '/products/:id/edit', to: 'products#edit', as: 'edit_product'
  patch '/products/:id', to: 'products#update'
  delete '/products/:id', to: 'products#delete'
  # resources :products    
end

This is my products_controller.rb

class ProductsController < ApplicationController
  
  def delete
    @product = Product.find(params[:id])
    @product.destroy
    redirect_to products_path
  end

  private
    def product_params
      params.require(:product).permit(:name, :description, :price)
    end
  
end

And this is my index.html.rb, where I'm listing the products.

<h1>Products list</h1>
<table>
  <tr>
    <thead>
      <th>Name</th>
      <th>Description</th>
      <th>price %></th>
    </thead>
  </tr>
  <% @products.each do |product| %>
    <tr>
      <td><%= product.name %></td>
      <td><%= product.description %></td>
      <td><%= product.price %></td>
      <td>
        <%= link_to "Update", edit_product_path(product) %>
        <%= link_to "Delete", product, method: :delete, data: { confirm: 'Are you sure?' } %>
      </td>
    </tr>
  <% end %>
</table>

Answer 1

Looks like you are using Rails 7 since method: :delete is no longer working without ujs .

So, it leads to GET request and there is really no such route in your config. This issue was discussed in this question and the solution is:

  <%= link_to "Delete", product, data: {  turbo-method: :delete, confirm: 'Are you sure?' } %>

But there is a catch: looks like not all versions of Rails 7 support this behavior. And this will not work inside the form because actual mechanics of changing the method is based on creating a hidden form. There is a discussion in the issue and a hint in the docs : you should use links only for GET requests. For other requests use actual forms or buttons, so button_to will do the job better since it can change method and use confirmation prompt.

I infer that you try to do the show action. If it is the case, the HTML verb is wrong. You are using post instead of get .

The POST verb is most often utilized to create new resources.

The HTTP GET method is used to read (or retrieve) a representation of a resource
