Question

how can I execute such query in django:

SELECT * FROM keywords_keyword WHERE id not in (SELECT keyword_id FROM sites_pagekeyword)

In the latest SVN release we can use:

keywords = Keyword.objects.raw('SELECT * FROM keywords_keyword WHERE id not in (SELECT keyword_id FROM sites_pagekeyword)')

But RawQuerySet doesn’t support filter(), count(), indexing and other things. Is there another way?

Answer 1

Keyword.objects.exclude(id__in=PageKeyword.objects.all()

Keyword.objects.exclude(id__in=PageKeyword.objects.values('keyword_id'))

For future reference, exclude is documented here.

Edit: Yes, you are right; I corrected my answer. See above.

Edit: Even more readable:

Keyword.objects.exclude(pagekeyword__in=PageKeyword.objects.all())
