Rubocop with Ruby on Rails

What?

RuboCop is a static code analysis tool for checking Ruby code for compliance with a set of coding standards and best practices. It may be used to check for things like long methods, complex conditionals, and variables that aren’t being used automatically.

When used with Ruby on Rails, RuboCop can help make sure that the codebase follows the rules of the Rails framework and has a consistent style of code throughout the project. It can also be used to look for common security problems, like SQL injection vulnerabilities and cross-site scripting (XSS) attacks.

RuboCop uses a set of built-in rules (or “cops”) to check for specific issues in Ruby code. These rules are organized into different categories, such as “style", “lint" and “security." Some examples of the types of issues that RuboCop can check for include:

• Style: RuboCop can check for issues related to code style, such as indentation, line length, and naming conventions. It can also check for code that violates the Ruby community’s widely accepted style guide, called Ruby Style Guide.
• Lint: RuboCop can check for common code smells, such as long methods, complex conditionals, and unused variables. It can also check for issues related to performance, such as expensive method calls.
• Security: RuboCop can check…
