find_or_create_resource(resource_class, identifiable_attributes, additional_attributes={}, &constructor) click to toggle source

If a resource_class with matching identifiable_attributes exists, return that user and present a resource_already_exists message.

Otherwise, create a new instance of resource_class using the identifiable_attributes and additional_attributes.

@param [Class] resource_class: The class to create the resource in. EG: User @param [Hash] identifiable_attributes: A hash of attributes and values that can be used to

identify the given resource. EG: {email: "jordan@example.com"}

@param [Hash] additional_attributes: A hash of attributes and values that don’t identify

the given resource, but should be assigned to the new resource.
