Comment (by caioariede): It looks like there's an issue with the user-defined function used by the SQLite backend to make arithmetic calculations: https://github.com/django/django/blob/master/django/db/backends/sqlite3/base.py#L416 It only expects microseconds, timedeltas and datetime objects. In the given example, it also would need to expect an integer (the percent). This works with the PostgreSQL backend but not with the SQLite backend. -- Ticket URL: <https://code.djangoproject.com/ticket/25287#comment:6> Django <https://code.djangoproject.com/> The Web framework for perfectionists with deadlines. -- You received this message because you are subscribed to the Google Groups "Django updates" group.
