Hi,
require 'rubygems'
require 'dm-core'
DataMapper.setup(:default, 'sqlite3::memory:')
class Foo
include DataMapper::Resource
property :id, Serial
property :name, String
has n, :bars
end
class Bar
include DataMapper::Resource
property :id, Serial
property :name, String
belongs_to :foo
end
DataMapper.auto_migrate!
@foo = Foo.new(:name => 'baz')
@foo.bars = [Bar.new(:name => 'lala'), {:name => 'diudiu'}]
puts @foo.save
@foo = Foo.first
@foo.bars = [Bar.new(:name => 'test'), {:name => '123'}]
puts @foo.save
=>
true
false
How is this meant to work?
