I have 3 models PersonType, Person and Album. On a person_detail page
I want to pull the person albums as an artist(person_type).
I want to pull the person albums as an composer(person_type).
I want to pull the person albums as an lyricist(person_type).
or
all the albums of the person he is associated with
I am using the following code
{% if object.album_set.all %}
<ul>
{% for album in object.album_set.all %}
<li><a href="{{ album.get_absolute_url }}">{{ album.title }}</a></
li>
{% endfor %}
</ul>
{% endif %}
but nothing shows up, can anyone please correct me.
