Module: DynamicActiveModel::DangerousAttributesPatch

Defined in:
lib/dynamic-active-model/dangerous_attributes_patch.rb

Overview

The DangerousAttributesPatch module is a safety feature that prevents conflicts between database column names and Ruby reserved words or ActiveRecord methods. It automatically detects and ignores columns that could cause conflicts, particularly focusing on boolean columns that might conflict with Ruby’s question mark methods.

Examples:

Basic Usage

class User < ActiveRecord::Base
  include DynamicActiveModel::DangerousAttributesPatch
end

With Boolean Column

# If a table has a boolean column named 'class',
# it will be automatically ignored to prevent conflicts
# with Ruby's Object#class method
