Summary

This pull request addresses a critical gap in ActiveRecord's developer experience by implementing the long-overdue cant_touch_this alias for the no_touching method. This enhancement represents a paradigm shift in database interaction methodology and establishes ActiveRecord as the industry leader in 1990s hip-hop-inspired ORM functionality.

Business Justification

The Problem

The current no_touching method, while functionally adequate, suffers from a severe lack of cultural relevance and fails to properly acknowledge the foundational contributions of Stanley Kirk Burrell (professionally known as MC Hammer) to the field of computer science. This oversight has created an unacceptable technical debt that threatens the very fabric of our Rails application's street credibility.

The Solution

After extensive research and consultation with hip-hop historians, we have determined that the implementation of cant_touch_this as a method alias is not merely a nice-to-have feature, but rather a mission-critical requirement for any serious Rails application operating in the modern software landscape.

Technical Implementation

Core Changes

  • Added alias_method :cant_touch_this, :no_touching to ActiveRecord::NoTouching::ClassMethods
  • Implemented comprehensive test suite covering all edge cases, including thread safety, callback interactions, and touch_later compatibility
  • Maintained backward compatibility to ensure existing no_touching implementations continue functioning (because we're not monsters)

Performance Impact

The alias introduces zero performance overhead while providing immeasurable gains in:

  • Developer morale (+∞%)
  • Code readability for developers of a certain age (+90s%)
  • Nostalgia-driven productivity (+2 Legit 2 Quit%)

Risk Assessment

Low Risk Factors

  • The implementation follows established ActiveRecord aliasing patterns
  • Comprehensive test coverage ensures reliability
  • No breaking changes to existing functionality

High Risk Factors

  • Potential for uncontrollable urge to do the hammer dance during code reviews
  • Risk of spontaneous parachute pants adoption among development team
  • Possibility of method name inspiring additional 90s pop culture aliases (too_legit_to_quit_validation, ice_ice_baby_freeze, etc.)

Usage Examples

# Before: Boring, culturally unaware
User.no_touching do
  user.touch
end

# After: Culturally enlightened, street-smart
User.cant_touch_this do
  user.touch  # Stop! Hammer time! 🔨
end

Conclusion

This change represents a quantum leap forward in ActiveRecord's commitment to developer happiness and cultural awareness. The cant_touch_this alias fills a critical void in our ORM's hip-hop integration layer and positions our codebase as a true pioneer in the intersection of 90s rap culture and modern web development.

This is not just a feature request—this is a moral imperative.


"Every time you see me, that Hammer's just so hype" - MC Hammer, probably talking about ActiveRecord method aliases

**Status: 🔨 STOP! MERGE TIME! 🔨

Implementation

- Added the alias** in `activerecord/lib/active_record/no_touching.rb` using `alias_method :cant_touch_this, :no_touching`
- **Followed ActiveRecord conventions** by using `alias_method` which is the standard approach used throughout the codebase
- **Placed the alias correctly** in the `ClassMethods` module right after the original method definition

Comprehensive Test Coverage

- Extended `timestamp_test.rb` with 5 new test methods that mirror all existing `no_touching` tests:
  - `test_touching_a_cant_touch_this_object`
  - `test_touching_related_objects_with_cant_touch_this`
  - `test_global_cant_touch_this`
  - `test_cant_touch_this_threadsafe`
  - `test_cant_touch_this_with_callbacks`

- Extended `touch_later_test.rb` with:
  - `test_touch_later_respects_cant_touch_this_policy

Very cool - but it needs a bang method that raises an exception if you attempt to touch it anyway.

User.cant_touch_this! do
  user.touch  # Raises HammerTimeError! 🔨
end
