NDB structuredProperty randomly converting actual value.

[protodmorgan]

I'm working with a nested json I'm converted into NDB models that are structured. However, the last line of my attempt to contructed the model randomly converts the actual value. I might just be doing something wrong, but I asked on stackoverflow and haven't seen a response. I'm calling a bug at this point due to my testing.

data being passed in..

• "deviceId": "TEST",
• "settings": "{\"product\": \"bread\", \"sensorConfig\": [{\"lowerRange\": \"0\", \"upperRange\": \"1000000\", \"type\": \"MO\", \"description\": \"Slot 0 moisture\", \"label\": \"MO\"}, {\"lowerRange\": \"70\", \"upperRange\": \"400\", \"type\": \"TC\", \"description\": \"Slot 0 bread temp\", \"label\": \"Slot 0 temp\"}], \"name\": \"Jay Hunt\", \"algorithm\": {\"setpoint\": \"572000\", \"version\": \"1.2\", \"name\": \"absolute value\", \"setpointUnits\": \"hz\"}, \"title\": \"white bread medium\", \"level\": \"5\", \"productBrand\": \"Wonder Brand\", \"mode\": \"toast\", \"productType\": \"white\", \"action\": \"create\", \"htpGen\": \"2.1\", \"firmwareVersion\": \"1.3.12\", \"productKeywords\": \"bread,white,medium\"}"

                                                type=settings['sensorConfig'][0]['type'],
                                                label=settings['sensorConfig'][0]['label'],
                                                description=settings['sensorConfig'][0]['description'],
                                                lowerRange=int(settings['sensorConfig'][0]['lowerRange']),
                                                upperRange=int(settings['sensorConfig'][0]['upperRange'])),
                                            SensorConfig(
                                                type=settings['sensorConfig'][1]['type'],
                                                label=settings['sensorConfig'][1]['label'],
                                                description=settings['sensorConfig'][1]['description'],
                                                lowerRange=int(settings['sensorConfig'][1]['lowerRange']),
                                                upperRange=converted,   *ERROR HERE*
                                            )]))

So, last line where upperRange=converted No matter how i pass in the value. App engine throws back an error BadValue got u'5' expect Int. Even tho above shows the value is actually 400 and is INT.

IF I just pass in settings['sensorConfig'][1]['upperRange'] with out conversion. I get an error that I expect which is Type Error Unicode "400". So basically if I'm not converting the value type...it see it correctly. If I change the IntergerProperty to StringProperty I see u'5' again. If I hard code a value instead of passing in a variable I still see it try passing in u'5'. If I'm doing something wrong I'm at a lost on what.

Presumably you've seen #228.

I have, but seems to happen even if I switch to LocalStructuredProperties as well.
