Easily and consistently inherit attributes and configurations. This is particularly designed to work well with Rspec, which creates new inherited classes during each context.
Inheritable accessors comes with 3 inheritable components that can be used: an iheritable hash, set, and option accessor.
class Parent
include InheritableAccessors::InheritableHashAccessor
inheritable_hash_accessor :options
options[:a] = 1
end
class Child < Parent
options[:b] = 2
end
item = Child.new
# deleted items do not affect parent items
item.delete(:a)
item.options[:c] = 3
Parent.options.to_hash
#=> {a: 1})
Child.options.to_hash
#=> {a: 1, b: 1})
item.options.to_hash
#=> {b: 2, c: 3})class MyRequest
include InheritableAccessors::InheritableHashAccessor
include InheritableAccessors::InheritableOptionAccessor
inheritable_hash_accessor :request_opts
inheritable_option_accessor :path, :action, :params, for: :request_opts
# passing an argument to the accessor will "set" that value.
action "GET"
action # => "GET"
# passing a block will use the value of the block, but *only* when it is
# called. Block values will be memoized after the first run.
path { secret_path }
protected
def secret_path
"/secret_path"
end
end
request = MyRequest.new
request.path # => "/secret_path"
request.path "/other_path"
request.path # => "/other_path"
