Hi, Wonder if someone can help. I have a piece of code (filtched from elsewhere) that retrieves the comments for a particular Entry (blog post):
Comment.objects.filter(content_type=ContentType.objects.get_for_model(Entry), object_pk__in=Entry.objects.filter(title=self.title)) Problem is, that with Postgres 8.3 (and seemingly Django 1.2.1), this command fails: " django.db.utils.DatabaseError: operator does not exist: text = integer HINT: No operator matches the given name and argument type(s). You might need to add explicit type casts. " Having searched around in various forms this appears to be a sort of known problem (see http://code.djangoproject.com/ticket/10015). The issue is that object_py in Comments is a "text" field, whereas the id field in Entry is an int - hence a cast is required. I can make the actual SQL work in Postgres 8.3 by altering the start of the WHERE to be: "WHERE (cast(django_comments.object_pk as int) IN (SELECT" .... i.e. adding the 'cast'. So, my question is: what's the best way to go about this in Django 1.2.1 with Postgres 8.3? (8.3.8 to be exact). Any thoughts/ recommendations most welcome. FYI - this is for use with Djapian.
