Rein

Overview

ReinBuild Status is an innovative gem that enhances the ActiveRecord framework by introducing a set of database constraints. This tool allows developers to enforce data integrity at the database level, which is crucial for maintaining the sanity of data. By leveraging Rein, users can easily integrate essential constraints directly into their migrations without needing to resort to complex SQL commands. With its user-friendly approach, Rein simplifies the task of ensuring that only valid data is stored in the database.

The gem is particularly notable for its reversible migration methods, allowing developers to apply and roll back constraints seamlessly. Whether working with foreign keys, unique values, or numerical requirements, ReinBuild Status offers flexible solutions for various data integrity scenarios. This tool fills a significant gap left by ActiveRecord, empowering developers with enhanced control over their database constraints.

Features

• Foreign Key Constraints: Easily define relationships between tables to ensure data consistency, preventing orphaned records.
• Unique Constraints: Enforce uniqueness on specified columns, preventing duplicate entries within your database.
• Exclusion Constraints: Ensure that no two rows in a specified combination of columns overlap, maintaining unique sets of values.
• Inclusion Constraints: Validate that data falls within a particular set of values, ensuring compliance with business rules.
• Length Constraints: Set limits on the length of string fields, safeguarding against overly long input from users.
• Numericality Constraints: Verify that values in specific columns are numbers and adhere to defined numerical rules.
• Presence Constraints: Ensure that certain fields are always populated, enforcing mandatory data entry.
• Reversible Migrations: All methods implemented in Rein are reversible, making it easy to add or remove constraints as needs evolve.
