Instance Method Details

#blueprint(name_or_attrs, attrs = {}) ⇒ Object

Two forms of this method can be used. First one is typically used inside blueprint block. Essentially it does same as create!, except it does bypass attr_protected and attr_accessible. It accepts only a hash or attributes, same as create! does.

blueprint :post => [:user, :board] do
  @user.posts.blueprint(:title => 'first post', :text => 'My first post')
end

The second form is used when you want to define new blueprint. It takes first argument as name of blueprint and second one as hash of attributes. As you cannot use instance variables outside of blueprint block, you need to prefix them with colon. So the example above could be rewritten like this:

Post.blueprint(:post, :title => 'first post', :text => 'My first post', :user => d(:user)).depends_on(:board)
