Rails 7 completely redefines what it means to produce fantastic user experiences and provides a way to achieve all the benefits of single-page applications - at a fraction of the complexity. Rails 7 integrates the Hotwire frameworks of Stimulus and Turbo directly as the new defaults, together with that hot newness of import maps. The result is a toolkit so powerful that it allows a single individual to create modern applications upon which they can build a competitive business. The way it used to be.
Ruby on Rails helps you produce high-quality, beautiful-looking web applications quickly - you concentrate on creating the application, and Rails takes care of the details. Rails 7 brings many improvements, and this edition is updated to cover the new features and changes in best practices.

Eliminate tedious configuration and housekeeping, seamlessly incorporate JavaScript, send and receive emails, manage background jobs with ActiveJob, and build real-time features using WebSockets and ActionCable. Test your applications as you write them using the built-in unit, integration, and system testing frameworks, internationalize your applications, and deploy your applications easily and securely.
Rails 1.0 was released in December 2005. This book was there from the start, and didn't just evolve alongside Rails, it evolved with Rails. It has been developed in consultation with the Rails core team. In fact, Rails itself is tested against the code in this book.
All you need is a Windows, Mac OS X, or Linux machine to do development on. This book will take you through the steps to install Rails and its dependencies. If you aren't familiar with the Ruby programming language, this book contains a chapter that covers the basics necessary to understand the material in the book.
I am learning ruby on rails following the book agile development. Last thing I did, I created the Checkout part: I added the action to the controller, and the method for the instance variables of the model. Everything is working as expected, ... to a certain degree.
I would look at the code for adding a product to the cart, the validations look correct, the model defines the business rules, relationships between the objects (each object defined by a controller has a table (row) in the database).
If a part of your code deletes an object (table row) before another object (table row entry) is saved this will break the relationship in the databse which appears as a validation error as well, in my case, I was executing a charge within its own rescue block after the order save command (the first part of this deletes the cart object), the stripe charge lines of code were dictating when the order was saved which was after the lines of code in which the order was saved, this caused the error "invalid line items", once the charge code was put before @order.save and within a single begin rescue block the orders saved without error [link]rails 4 stripe payment causing line item invalid error
Agile Web Development with Rails first takes you into the world of Rails (a new Web development framework based on the Ruby language) with a simple Web application, then takes you through some of the details of Rails after you get familiar with it, such as Active Record, Action Controller, etc. Some of the best practices of Rails let readers feel the beauty of Rails to an extreme, and can be well referenced in your own daily development. Eventually, you will realize that Web development can benefit a lot from the application of agile development principles.

Perhaps the most commonly used programming language in Agile development is Ruby. The primary focus of this method is to develop full-scale web applications mirroring the Model-View-Controller architecture. The reason ROR( Ruby on Rails) is so popularly associated with Agile is that it needs just a few lines of code to build a whole web application and generally requires less configuration than you usually need when you use other applications.
Ruby is an object-oriented programming language It was first created and designed by Yukihiro in Japan sometime around the 1990s. The syntax that you use in Ruby is like that of Perl. The semantics used in it is like that of Smalltalk. Ruby uses the C dialect. David Heinemeier, the creator of Rails, wrote its framework using Ruby in 2003 with the initial release around the year 2005.
From the past few years, Ruby on Rails development has become incredibly popular with startups looking to iterate on the first version of their product quickly. The ROR framework has grown to encompass an extensive list of features. The features include asynchronous emails, foreign keys, a web console as well as active job and adequate records management.
Since the team members are highly qualified and experienced, each of them has the expertise in certain activities such as designing, coding, testing, and quality acceptance. At the end of each sprint, the product-owner verifies the product feature that the team develops. Once the PO is okay with the product, they then present it to the stakeholders for their review. Stakeholders comments are well noted and worked upon to improve the product in the current product development cycle. The entire process is repeated several times in the form of sprints until the development of all the constituent product features is complete.
Rails has its own set of conventions that can speed up the development process. Rails applications in their most basic form save programmers a considerable amount of development time. In contrast, Java requires engineers to configure just about everything, where with Rails there are a number of predefined conventions that drive development standards.
REST stands for the Representational State Transfer. It is one unique architectural software style that is the backbone of numerous modern applications. The primary emphasis of REST is to better the relationship between the client and the server. It is also useful in making the structural components of an app a lot more logical and compatible with one another. ROR makes heavy use of the REST framework.

Choosing Ruby on Rails for your digital product development project can help businesses stay competitive, responsive, and agile in the fast-paced business environment by enabling quick software development.
Ruby is a concise language with a lean codebase contributing to faster development and integration. Rails was created with many built-in libraries, and starting a new project with Rails automatically includes lines of skeleton code that are common across most applications.
As a business, you want these features for your development to lower your time to market and receive a lot of audience feedback. These factors increase a startup's probability of success and validate existing ideas.
Speed plays a crucial role in software development, as it impacts the time-to-market, cost, customer satisfaction, and overall agility of businesses in responding to changing market demands and customer needs.
Here comes Ruby on Rails that is known for its ability to facilitate fast software development due to its convention over configuration approach, agile development principles, expressive Ruby language, rich ecosystem, and built-in testing framework, making it an excellent choice for businesses seeking to develop software quickly and efficiently.
Using them is always faster than developing these features from scratch. Though the time-save depends on what you need to build, Ruby developers have shared that building with Rails cuts down development time in half when comparing this to building from scratch.
By utilizing the Ruby programming language, Rails has access to a large repository of third-party components (gems), which greatly accelerates application development by providing pre-built functionalities, eliminating the need for developers to create these features from scratch.
For example, authentication packages (registration, login pages, or through social media providers like Facebook or Google) are very easy to set up, thanks to Devise gem. Building the administration panel is simple with ActiveAdmin.
The convention over configuration strategy saves dozens of configuration lines and boilerplate code. Favoring sets of rules that come with the Rails framework can cut the number of decisions that need to be made, keeping code simplicity and flexibility simultaneously. 152ee80cbc
