Overview

Passive Columns is a powerful gem that enhances Active Record, allowing developers to retrieve database columns on demand. This is especially beneficial when working with Active Record in Rails 6.1 and Ruby 2.7 and above, as it streamlines the process of managing model attributes while also improving performance. By selectively loading columns, you can avoid unnecessary database queries, which can be a game-changer for larger applications.

This gem addresses common issues faced by developers when certain columns are not needed for every operation, thereby preventing bloated queries and performance bottlenecks. With Passive Columns, you can exclude columns from default retrieval and load them only when necessary, striking a balance between efficiency and functionality.

Features

Selective Column Retrieval: By default, ActiveRecord excludes passive columns from retrieval, optimizing performance by not loading unnecessary data.
On-Demand Loading: Use the load_column method to fetch any column value from the database only when required, streamlining data management.
Integration with Rails: Compatible with Rails 6.1 and Ruby 2.7+, making it easy to incorporate into existing projects with minimal effort.
Simplified Validation: Allows you to manage validation rules separately for passive columns, preventing validation errors when attributes are not loaded.
Built-In Efficiency: Utilizes Rails' .pick method under the hood for efficient value retrieval, ensuring that even on-demand loading is fast and reliable.
Easy Installation: Adding Passive Columns to your project is straightforward by including it in your Gemfile and executing a simple command.
Open Source: The gem is licensed under the MIT License, providing flexibility and community support for developers.

Passive Columns is an excellent tool for any Rails developer looking to improve their application's performance and maintainability.
