hi,
some newbie questions here... after spending much time with
reading/testing I still have no solution; some help is needed and
appreciated.
here's the problem:
having a class definition with a custom sql statement:
class VMergeDocsInfo(models.Model):
....
def by_categories(self):
from django.db import connection
cursor = connection.cursor()
cursor.execute("SELECT DISTINCT doc_title FROM t_merge_docs")
return [row for row in cursor.fetchall()]
......
... and a view definition with:
paginate_by = 15
paginator =
ObjectPaginator(VMergeDocsInfo.objects.all().by_categories(),
paginate_by)
results in:
AttributeError
Exception Value: 'QuerySet' object has no attribute 'by_categories'
following is ok:
paginator =
ObjectPaginator(VMergeDocsInfo.objects.all()[0].by_categories(),
paginate_by)
objects = paginator.get_page(page)
return render_to_response('show_categories/index.html', {'objects':
objects})
but now comes the next problem:
return render_to_response('show_categories/index.html', {'objects':
objects, 'hits' : paginator.hits})
produces
TypeError
Exception Value: count() takes exactly one argument (0 given)
why? what's wrong with the paginator?
thank you in advance,
robert
