Hi altogether,
I'm still working on the Ruby-ORM-Adapter to OrientDB, focussing on the
behavior of embedded lists, lightweight edges
In Ruby they are serialized as ordinary Arrays. Thus - they should behave
like Arrays in the ORM-Adapter, too.
In Ruby the method "<<" is used to add an element to an array, thus in
activeOrient after initializing the Classes TestMode and LinkClass this code
59 new_record = TestModel.new_instance ll: [ ]
# new document with an empty array
60 (1..9).each do |i|
61 new_record.ll << LinkClass.new_instance( att: "#{i} attribute"
)
62 new_record.ll << i
63 end
creates an Array with 18 Elements:
1 attribute ; 1 ; 2 attribute ; 2 ; 3 attribute ; 3 ; 4 attribute ; 4 ; 5
attribute ; 5 ; 6 attribute ; 6 ; 7 attribute ; 7 ; 8 attribute ; 8 ; 9
attribute ; 9
each link to the LinkClass-Instance is followed by a Number
Now the surprise. When checking the Record in Studio I got:

..More(3)
The Numeric-Items are ignored, only the links are displayed, and only 9
Array-Elements are detected.
However, if I reverse the order of entries (adding first the number then
the link), Studio does not recognize the links but displays all elements.

Am I bending the Datamodel of Orientdb to much or is this just a bug in
studio?
