init_with(coder)
public
Initialize an empty model object from coder. coder must contain the attributes necessary for initializing an empty model object. For example:
class Post < ActiveRecord::Base end post = Post.allocate post.init_with('attributes' => { 'title' => 'hello world' }) post.title # => 'hello world'
