Hi,
I'm working on a similar solution in ruby.
Could'nd find any difficulty on the orientdb-side:
92 context 'work with multi dimensional Arrays', focus:true do
93 let( :multi_array ){ a = [1,2,3]; b = [ :a, :b, :c ]; [ a, b ] }
94 it 'intitialize' do
95 new_record = TestModel.create ll: multi_array
96 expect( new_record.ll ).to eq [[1, 2, 3], ["a", "b", "c"]]
97
98 end
99
100 it "use saved dataset for update" do
101 dataset = TestModel.create ll: [] # create schemaless
property type embedded
102 expect{ dataset.update set: {ll: multi_array } }.to change{
dataset.version }
103 # explicit reread the dataset
104 data_set = TestModel.last
105 expect( data_set.ll ).to eq [[1, 2, 3], ['a', 'b', 'c']]
106
107 end
108
109 end
11
The test passed:
