Question

Hi I have a user input form which takes date in 2011-05-12 format. I want to query the results using Q . But my database field is in datetime format something like 2011-05-18 08:36:34. I am giving the query like this

k = Posts.objects.filter(Q(review_email__contains = user), review_time = datetime(date)) where user is some username and date is the form inputvalue

If I execute the above query I am getting below error

Traceback (most recent call last):
File "<console>", line 1, in <module>
TypeError: 'module' object is not callable

Can some one help me in solving this. Thanks in advance

The error comes from not doing datetime.datetime, but as soon you fix that, you’re going run into incorrect results in your query. When you coerce the datetime.date to a datetime.datetime object it will be at midnight. Consequently, only Posts created exactly at midnight on that day will match.

You should do this instead:

Post.objects.filter(
     review_email__contains = user, 
     review_time__year=date.year, 
     review_time__day=date.day, 
     review_time__month=date.month,
 )

See the queryset reference for more info.

On a side note, you don’t really need to use the Q object in this.
