Just in case any of you want to do this...I've written a routine that enables you to save a Query/Expression object in the session.
I have a controller that uses a form to build a relatively complex query and I want other controllers to use that query to generate reports and graphs. I initially explored saving the query in the session as a string, but it just wasn't working for me so I bit the bullet and wrote a seralization routine that takes a Query object and extracts it into a dictionary strucuture. There's another function that does the reverse. It's all here in this slice: http://www.web2pyslices.com/slice/show/1489/save-query-in-session It needs more testing for edge cases (I just don't know enough about the DAL to do all of that). I've written it as a module, but ultimately it would be nice to have something like it as a method within the gluon.dal.Query class itself? Better yet, get the framework to automatically invoke it when saving a Query/Expression to session (like it does for rows).
