Method: ActiveAttr::Attributes::ClassMethods#attribute!

Defined in:
lib/active_attr/attributes.rb

#attribute!(name, options = {}) ⇒ AttributeDefinition

Defines an attribute without checking for conflicts

Allows you to define an attribute whose methods will conflict with an existing method. For example, Ruby’s Timeout library adds a timeout method to Object. Attempting to define a timeout attribute using .attribute will raise a DangerousAttributeError, but .attribute! will not.

Examples:

Define a dangerous attribute.

attribute! :timeout

Parameters:

  • name (Symbol, String, #to_sym) —

    attribute name

  • options (Hash{Symbol => Object}) (defaults to: {}) —

    attribute options

Returns:
