I have a handful of records that I would like to sort based on a computed value. Got the answer over here... like so:

I am hoping not to denormalize the data, but I guess I will if I have to.
it seems that the only way to get a queryset back is if you can get all of your logic into the sql queries.
When that is not possible, (I think) you need to denormalize the data
There is no point in converting a data list back to a query. A query object never holds data; it just represents a query to the database. It would have to fetch everything again if you made your list to a query, and that would be redundant and very bad performance-wise.
What you can do:
reputationfield is calculated; it's probably possible to order the data in the database somehow.
Ok...this post is now old BUT what you could do is get all the
ids of the objects in your list, then perform a
