A simple DSL for defining database seeds in Rails.

DeprecatedAttributes provides a straightforward and unobtrusive method for flagging deprecated attributes in your model. When these attributes are accessed, a warning message will be logged along with a trace of where the deprecated attribute was called. Additionally, an exception can be raised if desired.

DeprecateSoft is a lightweight Ruby gem that lets you gracefully deprecate methods in your codebase without breaking functionality. It wraps existing instance or class methods and lets you plug in custom before/after hooks for tracking usage via logging, Redis, DataDog, or any other observability tools. Once you verify in your tracking that a method is no longer called, you can remove it safely from your code base. This is especially useful in large codebases where you want to safely remove legacy methods, but first need insight into whether and where they're still being called. Hooks are configured once globally and apply project-wide. Fully compatible with Rails or plain Ruby applications.

This gem takes random numbers and gives them out.
