Overview

MigrationData is an innovative gem designed to enhance the reliability of database migrations in Rails applications. It resolves common issues associated with writing migrations that alter not only the database schema but also the underlying data. Often, developers face the risk of outdated migration code that can compromise data integrity, and this tool seeks to mitigate these risks by enforcing systematic testing and separation of data-related migration logic.

By allowing developers to define specific methods for data modifications, MigrationData ensures that migrations are executed safely without the fear of data corruption. Its structured approach encourages best practices in migration coding, making it an essential tool for Rails developers who prioritize stability and integrity in their applications.

Features

Safe Data Migrations: Provides a framework for writing migration code that protects against data corruption and outdated logic.
Separation of Concerns: Encourages the use of separate methods for data-related code, making it easier to maintain and test.
Testing Integration: Simplifies the process of writing tests for migrations by providing a dedicated structure for migration logic.
Custom Execution Flow: Allows for pre- and post-execution methods (#data_before, #data_after, etc.) to control when data migrations occur relative to standard migration methods.
Environment Configuration: Offers a simple way to skip data migration execution in specific environments to avoid conflicts with existing data, especially in test scenarios.
Detailed Method Order: Clearly defines the execution order of data methods during migration rolling up and down, facilitating understanding and implementation.
Supports Rails Best Practices: Aligns with Rails best practices for migration management, promoting healthier codebases through better structure and testing.
