In Ruby, the command ri is used to access the built-in documentation (also known as “RDoc”) of a library, class, method, or specific topic. ri is an abbreviation for “Ruby Interactive” or “Ruby Index.”

A comment in Ruby on Rails (and in programming in general) is a piece of text that is ignored by the interpreter when executing the code. Comments are used to provide explanations, documentation, or notes within the code to make it more understandable.

Rails 7.1 introduced a new method called ActiveRecord::Base::normalizes which can be used to declare normalizations for attribute values. This can be especially useful for sanitizing user input, ensuring consistent formatting, or cleaning up data from external sources.

In Ruby, both OpenStruct and Struct provide ways to create objects with predefined attributes. However, they differ in functionality and flexibility. Let’s explore the differences between OpenStruct and Struct, and showcase examples to illustrate their usage.

In Ruby on Rails, handling complex forms efficiently and maintaining clean and organized code is crucial. This is where Form Objects come into play. Let’s explore the concept of Form Objects and highlight the key differences between using a Form Object and a traditional form approach. Let’s dive in!

The presence of dead code in a Ruby on Rails application can lead to performance bottlenecks, increased maintenance costs, and unnecessary complexity. Fortunately, the Coverband Ruby gem offers a powerful solution for identifying and removing unused code.

Rails console is a powerful tool for interacting with your Rails application’s code and database. But what if you want to experiment with changes without affecting your production data? Enter the --sandbox option.

In this article, we’ll explore the concept of Presenters and how they can simplify view logic in Ruby on Rails, especially when conditionals are overused.

Error handling is a crucial aspect of writing robust and reliable code. In Ruby, exception handling provides a mechanism to gracefully handle and recover from errors during program execution. In this article, we will explore exception handling in Ruby, understand how to handle errors using begin-rescue blocks, and discuss best practices for effective error handling. We’ll cover key concepts and provide code examples to illustrate exception handling in Ruby.

Ruby is a dynamically-typed and highly flexible language that allows programmers to modify and extend the behavior of code at runtime. Metaprogramming is a powerful technique in Ruby that leverages its dynamic nature to write code that can generate or modify other code.

The Interactor gem is a powerful tool that simplifies the implementation of workflows in Ruby applications. By breaking down tasks into smaller components, known as interactors, and utilizing the context for data sharing, we can simplify business logic and improve code maintainability. In this blog post, we’ll explore how interactors can simplify business logic by implementing order fulfillment for an e-commerce application.

When working with Rails controllers, accessing data from incoming requests is a common task. Two commonly used objects for retrieving request data are params and request.env. Understanding the differences between these two objects and their appropriate usage is crucial for effective request handling and data retrieval in Rails applications.

Partials:

In a Rails application, rendering and redirecting are two common ways to handle responses in controllers. While both methods serve distinct purposes, understanding their differences is crucial for effective request handling and maintaining a smooth request/response cycle.

The each_cons method in Ruby on Rails is a versatile tool that simplifies iterating over consecutive pairs in a collection. With just a single line of code, we can perform tasks such as finding patterns or calculating differences between adjacent elements. In this blog post, we’ll explore the various use cases of each_cons, starting from simple examples and gradually progressing to more complex ones.

Working with multiple databases is a common requirement in many Rails applications. Whether you need to interact with legacy databases, implement data sharding strategies, or separate different types of data, Rails provides robust support for managing multiple databases.

Migrating from one file attachment library to another can be a challenging task, but with Rails’ built-in Active Storage, the process becomes much smoother.

Ruby 3.2 introduces a new Data class to define immutable value objects that contain a simple set of values. Similar to the Struct class in Ruby, it provides a simpler and more restricted API. In this article, we’ll explore what the Data class is and how it can be useful from a practical perspective.

In today’s digital landscape, the protection of sensitive data is of paramount importance. Encryption plays a crucial role in ensuring the confidentiality and integrity of sensitive information within your Ruby on Rails application. By implementing strong encryption techniques, you can significantly enhance the security of data at rest and in transit. In this article, we will explore how to leverage strong encryption for sensitive data in a Ruby on Rails application, along with code examples to guide you through the process.

In the digital age, ensuring the security of user accounts is paramount. One crucial aspect of account security is implementing strong password policies. By enforcing robust password requirements, you can significantly reduce the risk of unauthorized access and data breaches. In this article, we will explore how to implement strong password policies in a Ruby on Rails application, complete with code examples to guide you through the process.

In an increasingly digital world, ensuring the security of user accounts has become a critical concern for web developers. One effective method to safeguard user data and prevent unauthorized access is through Two-Factor Authentication (2FA). This authentication process adds an extra layer of security by requiring users to provide two forms of identification before accessing their accounts. In this article, we will explore how to implement 2FA in a Ruby on Rails application, with code examples to guide you through the process.

Ruby on Rails is a powerful web application framework that enables developers to build robust and scalable web applications. However, like any other web application, Rails applications are vulnerable to attacks if not properly secured. One of the most critical aspects of securing a Rails application is sanitizing user input.

Ruby on Rails is a powerful and popular web application framework that allows developers to build secure and scalable web applications. However, like any other web application, Rails applications are vulnerable to attacks if not properly secured. One of the most important aspects of securing a Rails application is secure session management.

Ruby on Rails is a popular web framework that is known for its security features. However, there are still many steps that developers need to take in order to ensure that their Rails applications are secure. One important step is to use strong parameters to protect against malicious input.

Input validation is an essential part of web application security, as it ensures that data entered by users is in the expected format and doesn’t contain any malicious content. In Ruby on Rails, input validation can be implemented using various methods and libraries. In this article, we’ll explore some of these techniques and provide code examples.
