I don't believe you can set a relationship like that after it's
already been saved, unless you clear what's already there. The second
"@foo.bars = [Bar.new(:name => 'test'), {:name => '123'}]" would imply
that that all the other @foo.bars would be cleared of the association
in the db.On Mar 15, 4:07 am, morbusg <[email protected]> wrote: > 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? -- You received this message because you are subscribed to the Google Groups "DataMapper" group.
