Active Record Attribute Methods Query

Adds query methods for attributes that return either true or false depending on the attribute type and value.

For Boolean attributes this will return true if the value is present and return false otherwise:

“‘ class Product < ActiveRecord::Base end

product = Product.new(archived: false) product.archived? # => false product.archived = true product.archived? # => true “‘

For Numeric attributes this will return true if the value is a non-zero number and return false otherwise:

“‘ product.inventory_count = 0 product.inventory_count? # => false product.inventory_count = 1 product.inventory_count? # => true “`

For other attributes it will return true if the value is present and return false otherwise:

“‘ product.name = nil product.name? # => false product.name = “ ” product.name? # => false product.name = “Orange” product.name? # => true “`
