Build a CRUD Web App with Ruby on Rails

If you are fairly new to Ruby on Rails (or forgot how to use it) and need a quick guide to creating a CRUD (create, read, update, destroy) web application, then you’ve come to the right place!

Below I have written some simple steps to creating a very simple application, linked to some documentation or a tutorial for each step, and included an example of what you might write for each step.

Here’s a nice, simple tutorial that gives some more context and explanation and walks you through these steps. This guide is also fairly easy to follow, much longer, and more detailed.

  1. Create a new app
rails new pets-app

  1. Launch a server and go to http://localhost:3000 in your browser to view your app
rails s

  1. Create models
rails g model owner first_name last_name age:integer email
rails g model pet name species owner_id:integer owner:belongs_to

  1. Set up associations
class Owner < ApplicationRecord
  has_many :pets
end

  1. Add validations
class Owner < ApplicationRecord
  has_many :pets
  validates :name, presence: true
end

  1. Run migrations
rails db:migrate

  1. Check your schema by looking at the db/schema.rb file

  2. Seed your database

Owner.create!(first_name:"Dan", last_name:"Weirdo", age: 18, email:"realemail@cool.com")
Pet.create!(name:"Snowball", species:"dog", owner_id:1)

  1. Test associations
Owner.first.pets
Pet.first.owner

  1. Test validations
owner = Owner.new(first_name: "")
owner.valid?
owner.errors.messages

  1. Create controllers and views
rails g controller owners index show new create edit update destroy
rails g controller pets index show new create edit update destroy

  1. Create routes using resources or manual routes
resources :pets
resources :owners

  1. Make sure your routes are working correctly by running your server

(rails s) and looking at each path that you created (i.e. /pets)

  1. Add/edit controller actions

Hint: scroll to the bottom for an example of standard controller actions

  1. Add/edit view files

Hint: “find on page” “new.html”, “index.html”, etc. to see examples

Another hint: the form_for helper

That’s it! Make sure you test your code as you go, and commit often.

How long does it take to develop/build an app?

With more of us using smartphones, the popularity of mobile applications has exploded. In the digital era, the number of people looking for products and services online is growing rapidly. Smartphone owners look for mobile applications that give them quick access to companies’ products and services. As a result, mobile apps provide customers with a lot of benefits in just one device.

Likewise, companies use mobile apps to increase customer loyalty and improve their services. Mobile Developers are in high demand as companies use apps not only to create brand awareness but also to gather information. For that reason, mobile apps are used as tools to collect valuable data from customers to help companies improve their offer.

There are many types of mobile applications, each with its own advantages. For example, native apps perform better, while web apps don’t need to be customized for the platform or operating system (OS). Likewise, hybrid apps provide users with comfortable user experience. However, you may be wondering how long it takes to develop an app.

To give you an idea of how long the app development process takes, here’s a short guide.

App Idea & Research

app-idea-research

_Average time spent: two to five weeks _

This is the initial stage and a crucial step in setting the project in the right direction. In this stage, you brainstorm ideas and select the best one. Apart from that, you’ll need to do some research to see if your idea is viable. Remember that coming up with an idea is easy; the hard part is to make it a reality.

All your ideas may seem viable, but you still have to run some tests to keep it as real as possible. For that reason, when Web Developers are building a web app, they analyze the available ideas to see which one is the best match for the targeted audience.

Targeting the right audience is crucial when you are developing an app. It saves time when shaping the app in the right direction as you have a clear set of objectives. Likewise, analyzing how the app affects the market is essential. During the research process, App Developers must gather information about potential competitors and threats. This helps the app owners develop strategies to tackle difficulties that come up after the launch.

The research process can take several weeks, but it determines how successful your app can be. For that reason, you must take your time to know all the weaknesses and strengths of the competitors, possible app strategies, and targeted audience.

The outcomes of this stage are app prototypes and the minimum feasible product.

Converting Your First Ruby CLI App Into a Ruby on Rails Web App

I have a CLI app that I created in Ruby for my first project at Flatiron School. I’m pretty proud of what I accomplished in just a couple of days. The app was built from scratch with nothing but the basic knowledge of Ruby that I learned in a little over a week. The fact that the user interface was working in time for my presentation was a huge relief. I had something to show everyone, and it brought me back to my early days of programming in a dos prompt — where my interest in coding truly began.

Image for post

my first Ruby CLI app

As cute and nostalgic as my little app was, I knew I wanted to build on it someday. My goal was to give my users a more visual and interactive experience as they navigated through my text-based app. I had visions of adding more user stories, and some cool ASCII graphics with a background soundtrack of cheesy arcade music. To add more under the hood and additional flair would take a bit of time and attention — and time was not on my side while attending school. Vowing to come back to it, I put my project expansion on the back burner while Mod 2 of Flatiron got underway.

In Mod 2, I began to learn Ruby on Rails. Rails is a web application framework that is written in Ruby and provides the backend functionality of a database and a web server, as well as the front end functionality of creating web pages for the user experience. It took me some effort to understand Rails, as I clumsily tried to keep track of all the many moving parts. I at times literally felt like I was on a runaway freight train, just trying to grasp at all the information that was coming at me. Rails is actually a beast of a framework, and there is A LOT to learn. One thing that was helpful to think about is that there is a process to everything you do when you are building things in Rails. This makes it easier to break the entire process down step by step. It is also true that the more you do something, the better you get at it. I learned a great deal by making mistakes and learning how to fix them.

The brilliance of Rails is that you can see your mistakes happening directly in the web browser as you code. Having an artistic and creative background, I need to see things and to learn by doing. Rails gives me both of those qualities. I also lack patience (I’m learning how to unlearn this), so the fact that there’s just so much you can do in such a short amount of time, when creating a basic web app, is a form of instant gratification for me. I can see what I’m building in real time, which gets me super excited to build things!

Why should we use Ruby on Rails for Software Development?

What is Rails, Ruby on Rails?

Rails is a server-side web application development framework written in the Ruby programming language. Its emergence in 2005 has influenced and impacted web application development to a vast range, including but not limited to seamless database tables, migrations, and scaffolding of views. In the simplest understanding, Rails is a highly productive and intuitive software developer. 

Websites and applications of any complexity can be achieved with Ruby on Rails. The software is designed to perceive the needs of ruby on rails developers and encourage them with the best way out. It is designed to allow developers to write lesser code while spiking productivity much more than any other framework or language. Ruby on Rails rapid application development offers everyday web development tasks easier and uniquely out-of-the-box, both with the same effectiveness.

The Ruby on Rails framework is based on two philosophies:

 

  • Don’t Repeat Yourself (DRY): It is a software development principle that ensures that every piece or entity of knowledge must be assigned with a single and unambiguous representation within a development system.

    It not only reduces the need to write lengthy codes but also eliminates the repetitive writing of codes. As a result, it provides a much more manageable web app development with the least possible bugs.

 

  • Convention over Configuration (CoC): It indicates the highly opinionated feature that the Ruby on Rails framework possesses. It offers ready-made solutions or the “best way out” for many tasks in a web application and defaults them to the convention without the need for external specification. The programmer using the software is required to specify only the unconventional aspects of the web application. 

Some of the commonly known websites built by the Ruby on Rails software developers are Instacart, Scribd, Shopify, Github, ConvertKit, Soundcloud, GoodReads, Airbnb. It finds its application in Sa-as Solutions, Social Networking Platforms, Dating websites, Stock Exchange Platforms, etc.

Why use Ruby on Rails: The multifold benefits

  • Community and its abundant resources 

    • There is a large community that is dedicated to Ruby on Rails that keeps it up-to-date and indeed encourages its family of developers to continue using it. They make sure the benefits are soaring with every update they make. 

    • The community is committed to developing several ready-to-use code packages, commonly known as gems, for its users. They discuss and announce new project launches, help each other with queries, and engage in framework discussions and betterment. While Ruby on Rails helps developers in rapid application development, it also connects and grows businesses together.

  • Project Scalability

    • To talk about scalability, we indicate the ability to grow and manage more and more user requests per minute (RPM). However, this depends on the architecture rather than the framework. The right architecture of Ruby on Rails web application development allows it to write bulky codes and programs as compared to early-stage difficulties with scalability. 

    • It uses the Representational State Transfer (REST) architecture. This will enable Rails to create efficient web applications based on Rails 6, launched last year in 2020, which addresses most scalability issues. The portable components are agile and help in a better understanding of new requirements and needful adaptations for any business. The framework and architecture allow both vertical and horizontal scalability.

  • Fast Application Development and Cost Effectiveness

    • Ruby on Rails is lucid, logical, and has lean code requirements, thereby cutting down redundancy and improving the overall development speed. Lesser amount of code is proportional to lesser time investment with optimal results. The more time it takes for development, the more expensive it becomes for the end customers.

    • Considering the ready-made code modules/packages (gems) available, Ruby on Rails development company will less time and money are spent creating and modifying Rails websites and applications. Another advantage that has made Ruby on Rails super attractive for startups is its use of Model-View-Controller (MVC) architecture. It has a component separation scheme that speeds up the web development process and fixes any errors that occur.  

  • Data Protection

    • Rails framework and the Ruby on Rails community put in a lot of efforts for data protection and security of its customer base. It is also one of the efficient frameworks for developing database-backed applications. 

    • The developers at Ruby on Rails cover many aspects of cybersecurity, including encryptions of  passwords, credit card information, and users’ personal database. Special measures are taken to prevent the framework from SQL injections and XSS attacks. 

  • Ruby on Rails Enterprise Application Development

    • Ruby on Rails simplifies the daily operations and lowers the cost of enterprise app developments. The prominent features include data management, seamless updating of applications, easy and efficient code development, and high scalability, as discussed above. 

    • Ruby on Rails enterprise application development is preferred by companies and is slightly cost-intensive. It can be easily integrated with third-party apps like Oracle Business, Oracle, Windows services, and others. Ruby enterprise app development allows the developers and programmers to solve the problems at the root level, given its transparency.

Bottom Line

There are several reasons to prefer Ruby on Rails discussed above and extend further to early detection of errors, reduced time to market, and easy adaptation for API developments. It makes web programming much easier and simplifies website building of any complexity. Its flexibility and acceptance among new developers and programmers make it the perfect, one-stop choice for software application development company in 2021.
