class Helio::APIResource
Attributes
save_with_parent[RW]
A flag that can be set a behavior that will cause this resource to be encoded and sent up along with an update of its parent resource. This is usually not desirable because resources are updated individually on their own endpoints, but there are certain cases, replacing a customer's source for example, where this is allowed.

save_nested_resource(name)

A metaprogramming call that specifies that a field of a resource can be its own type of API resource (say a nested card under an account for example), and if that resource is set, it should be transmitted to the API on a create or update. Doing so is not the default behavior because API resources should normally be persisted on their own RESTful endpoints.
Calls superclass method
# File lib/helio/api_resource.rb, line 32 def self.save_nested_resource(name) define_method(:"#{name}=") do |value| super(value) # The parent setter will perform certain useful operations like # converting to an APIResource if appropriate. Refresh our argument # value to whatever it mutated to. value = send(name) # Note that the value may be subresource, but could also be a scalar # (like a tokenized card's ID for example), so we check the type before # setting #save_with_parent here. value.save_with_parent = true if value.is_a?(APIResource) value end end
