Processing Level query by ID not working

[lsetiawan]

getProcessingLevels by ID not working since code is wrong. ProcessingLevel object has ProcessingLevelID not ProcessingLevelsID. See link or below:

if ids:
 q = q.filter(ProcessingLevels.ProcessingLevelsID.in_(ids))

I'll provide fix soon. Just want to put this here so I don't forget.
