Congratulations, you've successfully created and run your first Rails application. Now you can start building the specific features for your e-commerce site.

Essential Components of E-commerce Sites

Understanding MVC Architecture

The Model-View-Controller (MVC) architecture is central to Ruby on Rails and helps structure your application effectively. MVC divides your application into three interconnected components: Models, Views, and Controllers.

The Model represents the data and business logic of your application. In an e-commerce site, models could include User, Product, and Order. Models interact with the database, managing the data.

The View is responsible for presenting data to the user. Views render the user interface and handle the display logic. In Rails, views are typically written in HTML with embedded Ruby (ERB) for dynamic content.

The Controller acts as the intermediary between models and views. Controllers handle incoming HTTP requests, process data through models, and pass the results to the views for rendering.

By following the MVC architecture, you can maintain a clean separation of concerns, making your codebase easier to manage and scale as your e-commerce site grows.

Setting Up User Authentication

User authentication is crucial for any e-commerce site, ensuring that only authorised users can access certain features. In Ruby on Rails, you can implement authentication easily using gems like Devise.

To get started, add Devise to your Gemfile by including gem 'devise', then run bundle install to install the gem. Next, run rails generate devise:install to set up the initial configuration. Follow the instructions provided by Devise to ensure proper setup.

Generate a User model with Devise by running rails generate devise User. This command creates a model and migration file for users. Run rails db:migrate to apply the changes to your database. Devise provides built-in views for user registration, login, and password recovery, which you can customise to match your site's design.

With user authentication in place, only registered users can perform actions like placing orders or accessing their account details, enhancing the security and user experience of your e-commerce site.

Managing Products and Inventory

Managing products and inventory is a core feature of any e-commerce site. In Ruby on Rails, you can create a Product model to handle the data related to your products. You can also organize your products into categories, making it easier for customers to browse and for administrators to manage the product catalog. Start by generating a Product model with attributes such as name, description, price, and stock quantity using the command rails generate model Product name:string description:text price:decimal stock_quantity:integer

After generating the model, run rails db:migrate to apply the changes to your database. You can then create a controller and views to manage the CRUD (Create, Read, Update, Delete) operations for your products. This allows you to add new products, update existing ones, and manage inventory levels.

Additionally, consider implementing validations in your Product model to ensure data integrity, such as validating the presence of a name and price. By effectively managing products and inventory, you can maintain an organised catalogue and provide a seamless shopping experience for your customers.

Managing Orders and Transactions

Efficient order processing and transaction management are at the heart of any successful ecommerce site.
