Adding ArticlesController and View

Here's how to add an ArticlesController and its corresponding view files to your Rails application:

1. Generate Controller:

Run the following command in your terminal:

rails generate controller Articles

This will create the following files:

• app/controllers/articles_controller.rb
• app/helpers/articles_helper.rb
• test/controllers/articles_controller_test.rb
• app/views/articles (directory)

2. Define Routes:

In config/routes.rb, add routes for your articles resource:

Rails.application.routes.draw do
  resources :articles
end

This will create RESTful routes for managing articles, including:

• GET /articles: index (list all articles)
• GET /articles/new: new (form for creating a new article)
• POST /articles: create (create a new article)
• GET /articles/:id: show (display a specific article)
• GET /articles/:id/edit: edit (form for editing an article)
• PATCH /articles/:id: update (update an article)
• DELETE /articles/:id: destroy (delete an article)

3. Implement Controller Actions:

Open app/controllers/articles_controller.rb and define actions for each route:

class ArticlesController < ApplicationController
  def index
    @articles = Article.all
  end

  def show
    @article = Article.find(params[:id])
  end

  # ... other actions like new, create, edit, update, destroy
end

4. Create Views:

Inside the app/views/articles directory, create view files corresponding to each action:

• index.html.erb
• show.html.erb
• new.html.erb
• edit.html.erb
• _form.html.erb (partial for both new and edit)

5. Implement Views:

Populate each view file with the appropriate HTML and ERB code to display or collect data:

• index.html.erb:

  <h1>Articles</h1>
  <ul>
  <% @articles.each do |article| %>
  <li><%= link_to article.title, article %></li>
  <% end %>
  </ul>

• show.html.erb:

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

6. (Optional) Add Model:

If you don't already have an Article model, generate one:

rails generate model Article title:string body:text

This will create app/models/article.rb and run a migration to create the articles table in your database.

7. Start Server and Test:

Run rails server to start your application and access the article routes in your browser.

Additional Notes:

• Remember to implement the missing controller actions and view files for complete CRUD functionality.
• You can customize the generated code and add validations, associations, and other features to your model and controller as needed.
• Consider using tools like Simple Form or Formtastic to simplify form building in your views.

This provides a basic framework for adding an Articles resource to your Rails application.
