Question

I need to check is there any object exist for given time Interval? How can I do that?How can I translate this Mysql into Django:

SELECT * 
FROM  `event_event` 
WHERE (startDate BETWEEN  "2010-10-1" AND  "2010-10-5")
   OR (endDate BETWEEN  "2010-10-1" AND  "2010-10-5")

I am currently using

Event.objects.filter(Q(startDate__range(datetime(2010,10,1),datetime(2010,10,5)))|Q(endDate__range(datetime(2010,10,1),datetime(2010,10,5))))

But I am not getting any object when I am using Django filter.Please suggest me where I am wrong.

Answer 1

Do

print Event.objects.filter(Q(startDate__range(datetime(2010,10,1),datetime(2010,10,5)))|Q(endDate__range(datetime(2010,10,1),datetime(2010,10,5)))).query

And see what SQL it produces, it’ll help you spot the differences.
