Building a CRUD Application with Ruby on Rails: Step-by-Step Guide

#ruby #rails #learning

Let’s take a deep dive into building a fully functional CRUD (Create, Read, Update, Delete) application using Ruby on Rails. I will walk through each step of the process, providing technical examples and explanations to help you understand the concepts and implementation details. By the end of this guide, you will have a solid foundation in developing CRUD applications with Ruby on Rails.

Step 1: Install Ruby on Rails
Make sure you have Ruby and Rails installed on your system. You can install Rails using the following command:

gem install rails
Enter fullscreen mode Exit fullscreen mode

Step 2: Create a New Rails Application
Create a new Rails application using the following command:

rails new crud_app cd crud_app
Enter fullscreen mode Exit fullscreen mode

Step 3: Generate a Model

Generate a model for the application. In this example, we’ll create a Task model with a title and description.

rails generate model Task title:string description:text rake db:migrate
Enter fullscreen mode Exit fullscreen mode

Step 4: Generate a Controller
Generate a controller to handle the CRUD operations for the Task model.

rails generate controller Tasks
Enter fullscreen mode Exit fullscreen mode

Step 5: Define Routes
Open the config/routes.rb file and define the routes for the Tasks controller:

config/routes.rb 

Rails.application.routes.draw do resources :tasks root 'tasks#index' end
Enter fullscreen mode Exit fullscreen mode

Step 6: Implement Controller Actions

Open the app/controllers/tasks_controller.rb file and implement the CRUD actions:

app/controllers/tasks_controller.rb 

class TasksController < ApplicationController before_action :set_task, only: [:show, :edit, :update, :destroy] def index @tasks = Task.all end def show end def new @task = Task.new end def create @task = Task.new(task_params) if @task.save redirect_to @task, notice: 'Task was successfully created.' else render :new end end def edit end def update if @task.update(task_params) redirect_to @task, notice: 'Task was successfully updated.' else render :edit end end def destroy @task.destroy redirect_to tasks_url, notice: 'Task was successfully destroyed.' end private def set_task @task = Task.find(params[:id]) end def task_params params.require(:task).permit(:title, :description) end end
Enter fullscreen mode Exit fullscreen mode

Step 7: Create Views
Create views for the Tasks controller. You can use the default Rails scaffold views or customize them based on your needs.

Step 8: Run the Application
Start the Rails server and navigate to http://localhost:3000 to see your CRUD application in action.

rails server
Enter fullscreen mode Exit fullscreen mode

That’s it! You’ve now created a simple CRUD application with Ruby on Rails. You can further customize and enhance it based on your requirements.
