Instance Method Details

#from_json(json) ⇒ JsonModel

Process JSON input and return a JsonModel for the data.

This method must be invoked on a subclass of the correct type. Invoking it on JsonModel itself will do nothing. All parameters in the JSON are recursively mapped to their attribute names, based on :param on the attribute. Unknown parameters are ignored.

Parameters:

  • json (String) —

    the raw JSON string as returned by the API

Returns:

  • (JsonModel) —

    a JsonModel mapped against the provided JSON

def from_json(json)
  new(to_attributes(JSON.parse(json)))
end

#to_attributes(json) ⇒ Hash

Given a ruby Hash representation of raw JSON from the API (or a subset thereof), map all JSON parameter keys to attribute names

Parameters:

  • json (Hash) —

    a ruby Hash representing a subset of the overall JSON structure

Returns:

  • (Hash) —

    a new Hash with all keys mapped to their attribute names

def to_attributes(json)
  json = {} unless json.kind_of?(Hash)
  json.inject({}) { |hash, (key, value)| (attr_value = attribute_value(key, value)) ? hash.merge(attribute_key(key) => attr_value) : hash }
