[Python-Cache Binding] Unable to set $List property with 2D Python array

Question

Ivan Tioh · Apr 11, 2017

It is possible to update Cache object property from Python using the following Python code, with import of intersys.pythonbind3:

my_object.set("my_property",["A","B","C"])

However, I am unable to save 2D %List with 2D Python array like the following:

my_object.set("my_property",[["A","B","C"],["1","2","3"]])

I am not sure whether this is Python-Cache bind flaw or design issue. Is there any alternative/ workaround to do the same for above?

Our current Python binding only supports one dimensional lists.

I don't know of a work-around.

Please contact the WRC and discuss an enhancement request. Product Management will decide whether the enhancement request is approved, and if approved when scheduled.

Thanks,

Class my_class Extends %Persistent{

Property my_property As %List;

}

From Cache, I normally update my_property field with $lb($lb(...),$lb(...),...) data. So, I was expecting the following behaviors:

Python	Cache	Result
[1,2,3]	$lb(1,2,3)	OK
[[1,2,3],[4,5,6]]	$lb($lb(1,2,3),$lb(4,5,6))	Error
