Step 1: Setting Up Your Environment
Before diving into the development process, ensure you have Ruby, Rails, and the necessary dependencies installed on your system. A well-prepared environment is the first step toward smooth development.
Step 2: Creating Your Rails Application
Generate a new Rails application by entering the following commands into your terminal. The application will be the canvas upon which you build your shopping cart.
```bash
rails new AudioCart
cd AudioCart
```
Step 3: Crafting the Product Model
Start by creating a model to represent your products—whether they are audio files, videos, or books. This model forms the core of your product management system.
```bash
rails generate model Product title:string description:text price:decimal
rails db:migrate
```
Step 4: Forming the Cart Foundation
To manage user carts, create a model that represents a cart. This model acts as a container for the items users wish to purchase.
```bash
rails generate model Cart user:references
rails db:migrate
```
Step 5: Building the LineItem Connection
Generate a model to establish the connection between items and the cart. Line items are the bridge between products and the user's shopping cart.
```bash
rails generate model LineItem product:references cart:references quantity:integer
rails db:migrate
```
Step 6: Establishing Crucial Associations
Connect the models to ensure smooth interactions. By defining associations, you enable the seamless flow of data within your application.
```ruby
# app/models/product.rb
class Product < ApplicationRecord
has_many :line_items
end
# app/models/cart.rb
class Cart < ApplicationRecord
belongs_to :user
has_many :line_items
end
# app/models/line_item.rb
class LineItem < ApplicationRecord
belongs_to :product
belongs_to :cart
end
```
Step 7: Crafting Controllers and Views
Generate controllers for products, carts, and line items. Controllers handle the logic, while views present data to users.
```bash
rails generate controller Products
rails generate controller Carts
rails generate controller LineItems
```
Step 8: Navigating with Routes
Configure routes in `config/routes.rb` to map URLs to specific controller actions. Routes dictate how users navigate through your application.
Step 9: Designing User Interfaces
Create views under `app/views` for products, carts, and line items. These interfaces allow users to interact with your application in a user-friendly manner.
Step 10: Adding Products to the Cart
Enhance the Products controller by adding an action to add products to the cart. This crucial step enables users to build their shopping lists.
```ruby
def add_to_cart
product = Product.find(params[:id])
current_cart.line_items.create(product: product)
redirect_to products_path, notice: 'Product added to cart'
end
```
Step 11: Displaying the Shopping Cart
In the Carts controller, implement an action to display the contents of the cart. Users should have a clear view of their selected items.
```ruby
def show
@cart = current_cart
end
```
Step 12: Presenting the Cart in Views
In your Cart's view, iterate through line items to display product details and quantities. This visual representation helps users review their choices.
