def initialize(struct = {})
  # Set the initial unmapped struct
  self._unmapped = RecursiveOpenStruct.new
  # Build a RecursiveOpenStruct and a simple hash from the given data
  struct, hash = sanitize_data(struct)
  # Initialize associations and map them accordingly
  struct, hash = initialize_associations(struct, hash)
  # Initialize attributes and map unknown ones and pass back the known
  known = initialize_attributes(struct, hash)
  # Mass assign the known attributes via ActiveModel
  super(known)
  # Follow the ActiveRecord API
  yield self if block_given?

end

Instance Attribute Details

#_unmapped ⇒ Object

We collect all unknown attributes instead of raising while creating a new instance. The unknown attributes are wrapped inside a RecursiveOpenStruct to ease the accessibility. This also allows us to handle responses in a forward-compatible way.

Class Method Details

.inherited(child_class) ⇒ Object

Initialize the class we were inherited to. We trigger all our methods which start with inherited_setup_ to allow per-concern/feature based initialization after BaseEntity inheritance.

Parameters:

  • child_class (Class) —

    the child class which inherits us
