#374 closed defect (fixed)

[patch] Filtering BooleanField does not work with SQLite

Reported by: davidschein@… Owned by: adrian
Component: contrib.admin Version:
Severity: major Keywords: sqlite, filters, booleanfield
Cc: Triage Stage: Unreviewed
Has patch: yes Needs documentation: no
Needs tests: no Patch needs improvement: no
Easy pickings: UI/UX:


When Django wants to filter on a bool, it passes the parameter value as 'True' or 'False', whereas SQLite expects a 1/0 or '1'/'0' or even a proper Python True/False. But the string containing 'True'/'False' is lost on it. I am not sure where to address this in the code. The sqlite adapted does not know about models, so main might be the best place for logic to look for backend mappings (which need to be added obviously.) Trivially, the following hack/patch gets it working for sqlite.

David, do you have any way of testing to see if this patch works with MySQL/PostgreSQL? Seems like it should and I'll check it out when I get a chance, but if you can verify it works with other backends I'll check this fix in.
