I’m trying out ruby on rails for a project and up to this point its been great but when following the tutorial and i get to 8, for comments, it just doesnt work? ive try to go back and reread, but i always get the undefined method with the comments being the part not working. the route is there so i dont know what is wrong as ive followed the tutorial perfectly (i think) for the comment part.

NoMethodError in Articles#show
Showing C:/blog/app/views/articles/show.html.erb where line #17 raised:

undefined method `comments' for an instance of Article


16 <h2>Add a comment:</h2>
17 <%= form_with model: [ @article, @article.comments.build ] do |form| %>
18 <p>
19  <%= form.label :commenter %><br>
20  <%= form.text_field :commenter %>

here are my codes, which for the most part follow the tutorial

articles/show

<h1><%= @article.title %></h1>

<p><%= @article.body %></p>
<br>
<br>
<h3>
<%= link_to "Edit", edit_article_path(@article) %>  <br> 
<%= link_to "Destroy", article_path(@article), data: {
    turbo_method: :delete,
    turbo_confirm: "Are you sure?"
  } %>  <br>
<%= link_to "Home", root_path %>
</h3>

<h2>Comments</h2>
<% @article.comments.each do |comment| %>
  <p>
    <strong>Commenter:</strong>
    <%= comment.commenter %>
  </p>

  <p>
    <strong>Comment:</strong>
    <%= comment.body %>
  </p>
<% end %>

<h2>Add a comment:</h2>
<%= form_with model: [ @article, @article.comments.build ] do |form| %>
  <p>
    <%= form.label :commenter %><br>
    <%= form.text_field :commenter %>
  </p>
  <p>
    <%= form.label :body %><br>
    <%= form.text_area :body %>
  </p>
  <p>
    <%= form.submit %>
  </p>
<% end %>

comments_controller

class CommentsController < ApplicationController
  def create
    @article = Article.find(params[:article_id])
    @comment = @article.comments.create(comment_params)
    redirect_to article_path(@article)
  end

  private
    def comment_params
      params.require(:comment).permit(:commenter, :body)
    end
end

models/comments

class Comment < ApplicationRecord
  belongs_to :article
  
  validates :title, presence: true
  validates :body, presence: true, length: { minimum: 10 }
end

schema

ActiveRecord::Schema[7.1].define(version: 2024_06_07_161059) do
  create_table "articles", force: :cascade do |t|
    t.string "title"
    t.text "body"
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
  end

  create_table "comments", force: :cascade do |t|
    t.string "commenter"
    t.text "body"
    t.integer "article_id", null: false
    t.datetime "created_at", null: false
    t.datetime "updated_at", null: false
    t.index ["article_id"], name: "index_comments_on_article_id"
  end

  add_foreign_key "comments", "articles"
end

routes

Rails.application.routes.draw do
  root "articles#index"

  resources :articles do
    resources :comments
  end
end

here’s a screenshot of the page when i try to access an article
