jsonify() method for Q class in django.db.models.query_utils

[Austin Hunt]

Hi,

I have written a new recursive method along with documentation and testing that allows one to translate a Django Q object representing a complex query into JSON format for the purpose of easily re-using and editing complex queries that have been saved via pickling in a database. I am opening this ticket so that I can reference it in a pull request.

Thank you,

It's not appropriate to accept your own ticket. Most probably it would be more appropriate to release this as a third-party package (which of course would have to be a function that takes a Q object) and see if it gains widespread adoption, but I'll leave the ticket open for another opinion.

I agree with Tim. Q() is already deconstructible and pickleable so you can use pickle to save and reuse existing Q() objects. I think that support for editing Q objects by users is quite niche and it's not worth the extra complexity. It sounds like a third-party package is the best way to proceed.
