Hey everybody,
still have lots of problems with my associations that are not saved
corectly.
I am using a lot of nested file/folder type structures like the
following and
i really want to understand why i am unable to save the parent
relationship?
Thanks,
Sebastian
class File
include DataMapper::Resource
property :id, Serial
property :classtype, Discriminator
property :name, String
has 1, :parent, self
end
class Folder < File
has n, :childs, File
end
file = File.new(:name=>"File")
folder = Folder.new(:name=>"Folder", :childs =>[file])
file.parent = folder
folder.childs[0].parent.name.should =="Folder" # works
folder.save!
Folder.first(:name=>"Folder").childs[0].parent # gives nil
File.first(:name=>"File").parent # gives nil
