Thanks, I've added a function to the Enty models. It doesn't in some cases I
get good returns now. But not always.
Content is the name of the app. There is no PK-relation on the Category
class, but only the below on the Entry class.
class Entry(models.Model):
categories = models.ManyToManyField(Category, blank=True, null=True,
default = None)
def related_entries(self):
related =
Entry._default_manager.get(categories=self.categories.all())
return related
{% for related_entry in object.related_entries %}
<p><a href="{{ related_entry.get_absolute_url }}">{{
related_entry.title }}</a></p>
{% endfor %}
The related_entries work when all categories match. If there is a difference
(e.g. an Entry has multiple categories) it should return none. Instead I get
an error statement, which is probably because for each assigned category to
the entry a row is returned.
Caught DatabaseError while rendering: more than one row returned by a
subquery used as an expression
