Constructor Details

#initialize(attributes = {}) ⇒ Base

Initialize a new object. Send in attributes which we’ll dynamically set up read- and write methods for and assign to instance variables. How read- and write methods are defined might change over time when the DSL for describing column families and fields are in place

  read_attribute(:id)
end

#init_with(coder) ⇒ Object

Initialize an empty model object from coder. coder must contain the attributes necessary for initializing an empty model object. For example:

This should be used after finding a record from the database, as it will trust the coder’s attributes and not load it with default values.

class Person < MassiveRecord::ORM::Table
end

person = Person.allocate
person.init_with('attributes' => { 'name' => 'Alice' })
person.name # => 'Alice'
