Re: Lazy QuerySet command to get lists of objects and an attribute of a specific object

Dear Richard,

Thank you for your feedback. So there are multiple stage types associated with a sample, and I plan to check a priori whether

a sample has no stage types associated (whether equivalent to a user-defined null case). But for each stage type, it is not exceptional to 

have no stages. (Let me know if I'm sounding too vague)

basically there are (used Stage1, etc. here in place of actual stage names)

Stage1

Stage2

Stage3

...

and each Sample may have 0 - multiple associated StageN objects. Probably the best solution is revising my schema (in the long run).

But if try/catch expressions are expensive, and I'd prefer to check whether there are no stages 

then write try/catch, because of large number of samples I'd bee looping over.

Also, I was wondering if there is a way to combine the above two calls without calling stage1_set twice.

Thanks,

Moon
