Defined in:

lib/spiderfw/model/base_model.rb

#load(*params) ⇒ Object

Loads the object from the storage Acceptable arguments are:

• a Query object, or

• a Request object, or a Hash, which will be converted to a Request, or

• a list of elements to request

It will then construct a Condition with current primary keys, and call Mapper#load Note that an error will be raised by the Mapper if not all primary keys are set.
