If you want to know what makes Ruby on Rails the best framework for mobile and web apps, read this blog. The Fifth Collection, now a leading online vintage and luxury fashion portal, is a world-class Ruby on Rails example.

The business is now Southeast Asia’s No.1 online vintage and removed luxury website. The primary focus was to fulfil our client’s requirement of building an online portal that brought vintage fashion lovers closer to the products.

It has been useful for ROR projects in the past and offered a flexible approach to the development of The Fifth Collection as well. From the sellers' perspective, we included Manage account(order, inventory and shipping per seller), Support for managing Sale and Coupons, Revenue sharing model, Optimize shipping rates, Automate Online Advertising and scaling.

Since the application required automatically processing the pre-approval letters and generating loan calculations, our developers took it as a cool Ruby on Rails projects opportunity. They conducted complex calculations for creating a solution that enabled homebuyers to easily get letters.

Users could create their personal profile, manage their information through the centralized dashboard, know about updated interest rates, download pre-approval letters. Approve was one of those Ruby on Rails projects where we used high-functional Rutgers to integrate functionalities and make the application feature-rich.

Next in line is an amazing Ruby on Rails project that our developers worked on to improve the healthcare outcomes. Our Ruby on Rails developers built the perfect solutions that could match the therapist with clients based on their requirements.

Losing luggage while travelling was one of the biggest challenges someone could face, and the client identified that. The client told us that they want to help people claim compensation for lost luggage and file complaints the right way.

Such unique projects posses many challenges, one of which was to understand how to design the user-interface and integrate the claim filing process. These questions are related to travel disruptions and calculate the amount of compensation instantly.

Once the amount is calculated, the robot develops a template for the insurance claim and fills in all the details of the complaint. It is a platform for processing many PDF documents in varied layouts and publishing the content to major content management systems (CMS) like WordPress, Joomla, Drupal, Medium.com etc.

Along with Ruby on Rails, we used jQuery, MySQL, AWS, and Sinatra for building the application. But our client recognized that these magazines and instructional texts didn’t have any public visibility.

The primary challenge was to understand how to structure this data once it is extracted so that everyone can easily access it. The best option was to find a PDF parsing solution that can work with Ruby on Rails application development.

On top of that, our team provided constant support and maintenance for enhancing the application whenever it was necessary. Red mine is a Ruby on Rails -based project management software that includes a Gantt chart, calendar, wiki, forums, multiple roles, and email notification.

Betterment is a Rails -based online project management software that helps you to track work in a command and control environment. 9arrows is an Open source project management software written in Ruby on Rails and Extra framework.

It’s free and open-source software released under GNU General Public License (GPL). This guide is designed for beginners who want to get started with a Rails application from scratch.

Rails is a web application framework running on the Ruby programming language. If you have no prior experience with Ruby, you will find a very steep learning curve diving straight into Rails.

There are several curated lists of online resources for learning Ruby: Be aware that some resources, while still excellent, cover older versions of Ruby, and may not include some syntax that you will see in day-to-day development with Rails.

Rails is a web application development framework written in the Ruby programming language. It allows you to write less code while accomplishing more than many other languages and frameworks.

Don't Repeat Yourself: DRY is a principle of software development which states that “Every piece of knowledge must have a single, unambiguous, authoritative representation within a system”. By not writing the same information over and over again, our code is more maintainable, more extensible, and less buggy.

Convention Over Configuration: Rails has opinions about the best way to do many things in a web application, and defaults to this set of conventions, rather than require that you specify minutiae through endless configuration files. By following along with this guide, you'll create a Rails project called blog, a (very) simple weblog.

Before you can start building the application, you need to make sure that you have Rails itself installed. The examples below use $ to represent your terminal prompt in a UNIX-like OS, though it may have been customized to appear differently.

3.1.1 Installing Ruby Open up a command line prompt. On macOS open Terminal.app; on Windows choose “Run” from your Start menu and type cmd.exe.

Finally, you'll need Node.js and Yarn installed to manage your application's JavaScript. Rails comes with a number of scripts called generators that are designed to make your development life easier by creating everything that's necessary to start working on a particular task.

To use this generator, open a terminal, navigate to a directory where you have rights to create files, and run: This will create a Rails application called Blog in a blog directory and install the gem dependencies that are already mentioned in Gem file using bundle install.

If you're using Windows Subsystem for Linux then there are currently some limitations on file system notifications that mean you should disable the spring and listen gems which you can do by running rails new blog --skip-spring --skip-listen instead. The blog directory will have a number of generated files and folders that make up the structure of a Rails application.

Most of the work in this tutorial will happen in the app folder, but here's a basic rundown on the function of each of the files and folders that Rails creates by default: File/FolderPurposeapp/Contains the controllers, models, views, helpers, mailers, channels, jobs, and assets for your application.

You'll focus on this folder for the remainder of this guide.bin/Contains the rails script that starts your app and can contain other scripts you used to set up, update, deploy, or run your application.config/Contains configuration for your application's routes, database, and more. For more information about Rack, see the Rack website .db/Contains your current database schema, as well as the database migrations. GemfileGemfile.Lockheed files allow you to specify what gem dependencies are needed for your Rails application.

For more information about Bundler, see the Bundler website .lib/Extended modules for your application.log/Application log files.package.months file allows you to specify what NPM dependencies are needed for your Rails application. Rather than changing Rake file, you should add your own tasks by adding files to the lib/tasks directory of your application.README.Mathis is a brief instruction manual for your application.

In a typical Rails application this includes vendored gems.gitignoreThis file tells git which files (or patterns) it should ignore. To see it, you need to start a web server on your development machine.

JavaScript asset compression requires you have a JavaScript runtime available on your system, in the absence of a runtime you will see an execs error during asset compression. This will start up Puma, a web server distributed with Rails by default.

To see your application in action, open a browser window and navigate to http://localhost:3000. When you want to stop the web server, hit Ctrl+C in the terminal window where it's running.

In the development environment, Rails does not generally require you to restart the server; changes you make in files will be automatically picked up by the server. To get Rails saying “Hello”, you need to create at minimum a route, a controller with an action, and a view.

A controller action performs the necessary work to handle the request, and prepares any data for the view. In terms of implementation: Routes are rules written in a Ruby DSL (Domain-Specific Language).

Controllers are Ruby classes, and their public methods are actions. And views are templates, usually written in a mixture of HTML and Ruby.

When an action does not explicitly render a view (or otherwise trigger an HTTP response), Rails will automatically render a view that matches the name of the controller and action. To do so, we will add a route that maps the root path of our application to the appropriate controller and action.

Let's open config/routes.Rb, and add the following root route to the top of the Rails.application.routes.draw block: Text when we visit http://localhost:3000, confirming that the root route is also mapped to the index action of ArticlesController.

All of these are typical pieces of a web application that follows the MVC (Model-View-Controller) pattern. MVC is a design pattern that divides the responsibilities of an application to make it easier to reason about.

Since we have a controller and a view to work with, let's generate the next piece: a model. Additionally, models can interact with the application's database through a feature of Rails called Active Record.

Bin/ rails generate model Article title:string body:text Copy To help remember this convention, think of how you would call the model's constructor: we want to write Article.new(...), not Articles.new(...).

By default, the create_table method adds an id column as an auto-incrementing primary key. Inside the block for create_table, two columns are defined: title and body.

To play with our model a bit, we're going to use a feature of Rails called the console. The above output shows an INSERT INTO “articles” ... database query.

The <%= %> tag means “evaluate the enclosed Ruby code, and output the value it returns.” Anything you could write in a regular Ruby program can go inside these ERA tags, though it's usually best to keep the contents of ERA tags short, for readability.

But, since we do want to output the value returned by article. Title (for each article), we've enclosed that code in <%= %>. The Rails router maps the root route to the index action of ArticlesController.

The ERA code in the view is evaluated to output HTML. The server sends a response containing the HTML back to the browser.

Almost all web applications involve CRUD (Create, Read, Update, and Delete) operations. Rails acknowledges this, and provides many features to help simplify code doing CRUD.

Let's begin exploring these features by adding more functionality to our application. Let's add a new view that shows the title and body of a single article.

We start by adding a new route that maps to a new controller action (which we will add next). A route parameter captures a segment of the request's path, and puts that value into the paras Hash, which is accessible by the controller action.

For example, when handling a request like GET http://localhost:3000/articles/1, 1 would be captured as the value for :id, which would then be accessible as paras in the show action of ArticlesController. The show action calls Article. Find () with the ID captured by the route parameter.

As you might have guessed, we will do so by adding new routes, controller actions, and views. Whenever we have such a combination of routes, controller actions, and views that work together to perform CRUD operations on an entity, we call that entity a resource.

Rails provides a routes' method named resources that maps all the conventional routes for a collection of resources, such as articles. The values in the “Prefix” column above plus a suffix of _URL or _path form the names of these helpers.

Typically, in web applications, creating a new resource is a multi-step process. If there are no errors, then the resource is created and some kind of confirmation is displayed.

Else, the form is redisplayed with error messages, and the process is repeated. In a Rails application, these steps are conventionally handled by a controller's new and create actions.

The creation action instantiates a new article with values for the title and body, and attempts to save it. Otherwise, if the user refreshes the page, the browser will make the same request, and the mutation will be repeated.

Thus, the creation action can access the submitted title via paras and the submitted body via paras. Otherwise, a malicious user could potentially submit extra form fields and overwrite private data.

In fact, if we pass the unfiltered paras Hash directly to Article. New, Rails will raise a ForbiddenAttributesError to alert us about the problem. So we will use a feature of Rails called Strong Parameters to filter paras.

Let's add a private method to the bottom of app/controllers/articles_controller.Rb named article_params that filters paras. Handling invalid user input is another step of that process.

Rails provides a feature called validations to help us deal with invalid user input. Validations are rules that are checked before a model object is saved.

Class Article < ApplicationRecord validates :title, presence: true validates :body, presence: true, length: {minimum: 10} end Copy Additionally, it declares that the body value must be at least 10 characters long.

When we submit the form, the POST /articles request is mapped to the creation action. If any validation fails, article will not be saved, and app/views/articles/new.html.era will be rendered with error messages.

Else, the form is redisplayed with error messages, and the process is repeated. These steps are conventionally handled by a controller's edit and update actions.

If no validations fail and the update is successful, the action redirects the browser to the article's page. Else, the action redisplays the form, with error messages, by rendering app/views/articles/edit.html.era.

Even the code will be the same, thanks to the Rails form builder and resourceful routing. The form builder automatically configures the form to make the appropriate kind of request, based on whether the model object has been previously saved.

Because the code will be the same, we're going to factor it out into a shared view called a partial. Because partials are shared code, it is best practice that they do not depend on specific instance variables set by a controller action.

We can now update an article by visiting its edit page, e.g. http://localhost:3000/articles/1/edit. Deleting a resource is a simpler process than creating or updating.

And our resourceful routing (resources :articles) already provides the route, which maps DELETE /articles/:id requests to the destroy action of ArticlesController. We have chosen to redirect to the root path because that is our main access point for articles.

Now let's add a link at the bottom of app/views/articles/show.html.era so that we can delete an article from its own page: } option causes a confirmation dialog to appear when the link is clicked.

Both of these options are powered by a feature of Rails called Unobtrusive JavaScript (US). The JavaScript file that implements these behaviors is included by default in fresh Rails applications.

We can now list, show, create, update, and delete articles! This time we'll create a Comment model to hold a reference to an article.

Class Comment < ApplicationRecord belongs_to :article end Copy The difference is the line belongs_to :article, which sets up an Active Record association.

The (:references) keyword used in the bash command is a special data type for models. It creates a new column on your database table with the provided model name appended with an _id that can hold integer values.

In addition to the model, Rails has also made a migration to create the corresponding database table: The t.references line creates an integer column called article_id, an index for it, and a foreign key constraint that points to the id column of the articles table.

Rails is smart enough to only execute the migrations that have not already been run against the current database, so in this case you will just see: Active Record associations let you easily declare the relationship between two models.

Class Article < ApplicationRecord has_many :comments validates :title, presence: true validates :body, presence: true, length: {minimum: 10} end Copy These two declarations enable a good bit of automatic behavior.

As with the welcome controller, we will need to add a route so that Rails knows where we would like to navigate to see comments. This is another part of capturing the hierarchical relationship that exists between articles and comments.

In addition, the code takes advantage of some methods available for an association. As we have already seen, this calls the show action of the ArticlesController which in turn renders the show.html.era template.

Now you can add articles and comments to your blog and have them show up in the right places. As the render method iterates over the article.comments collection, it assigns each comment to a local variable named the same as the partial, in this case comment, which is then available in the partial for us to show.

Rails is smart enough to spot the forward slash in that string and realize that you want to render the _form.html.era file in the app/views/comments directory. The article object is available to any partials rendered in the view because we defined it as an instance variable.

Concerns are a way to make large controllers or models easier to understand and manage. This also has the advantage of reusability when multiple models (or controllers) share the same concerns.

If we want a count of public articles or comments to display on our main page, we might add a class method to Visible as follows: There are a few more steps to be carried out before our application works with the addition of status column.

We also have to permit the :status key as part of the strong parameter, in app/controllers/articles_controller.Rb : Another important feature of a blog is being able to delete spam comments.

Class CommentsController < ApplicationController def create article = Article.find(paras) comment = article.comments.create(comment_params) redirect_to article_path(article) end def destroy article = Article.find(paras) comment = article.comments.find(paras) comment.destroy redirect_to article_path(article) end private def comment_params paras.require(:comment).permit(:commenter, :body) end Copy The destroy action will find the article we are looking at, locate the comment within the article.comments collection, and then remove it from the database and send us back to the show action for the article.

Rails provides an HTTP authentication system that will work nicely in this situation. In the ArticlesController we need to have a way to block access to the various actions if the person is not authenticated.

We also want to allow only authenticated users to delete comments, so in the CommentsController (app/controllers/comments_controller.Rb) we write: Class CommentsController < ApplicationController http_basic_authenticate_with name: “DHH”, password: “secret”, only: :destroy def create article = Article.find(paras) # ... End # snippet for brevity Copy.

Now if you try to create a new article, you will be greeted with a basic HTTP Authentication challenge: Security, especially in web applications, is a broad and detailed area.

The easiest way to work with Rails is to store all external data as UTF-8. If you have made a mistake in this area, the most common symptom is a black diamond with a question mark inside appearing in the browser.

Another common symptom is characters like “A” appearing instead of “ü”. Rails takes a number of internal steps to mitigate common causes of these problems that can be automatically detected and corrected.

However, if you have external data that is not stored as UTF-8, it can occasionally result in these kinds of issues that cannot be automatically detected by Rails and corrected. If your text editor does not, this can result in special characters that you enter in your templates (such as é) to appear as a diamond with a question mark inside in the browser.

However, if your database is not using UTF-8 internally, it may not be able to store all characters that your users enter. For instance, if your database is using Latin-1 internally, and your user enters a Russian, Hebrew, or Japanese character, the data will be lost forever once it enters the database.

Make sure to check Edge Guides first to verify if the issues are already fixed or not on the master branch. Check the Ruby on Rails Guides Guidelines for style and conventions.
