Any limitations on string or dictionary size in Ignition?

[pturmel]

Look at the example for system.util.jsonDecode. Do that to assign to some top-level variable in a project script module. All usage elsewhere would be to someScript.someVar[someKeyOrSubscript].

Personally, I like running through such objects replacing dictionaries with my SmartMap subclass so that keys are accessible as properties:

Has anyone made an ORM work with Ignition transaction groups?

I've long been using a "SmartMap" extended dictionary that naturally allows property access to dictionary content. Create one with a tuple sequence of colName/colValue pairs and you suddenly have a very ORM-like row object. The one I like most delivers a None for missing keys automatically: #---------- # Handy tool for objects as "bags of properties" # by Peter Norvig, enhanced as a subclass of dict() by Philip J.
