If I'm following correctly and you want to access author profile photos
from querysets of Post objects: if you add related_name=‘profile’ to the
user field in the Profile model then you can add a method to the Post model:
def author_profile_photo(self):
return self.author.profile.photo
and then access the photos in the template using {{
post.author_profile_photo }}
You will need to catch cases where there is no photo either in the class
method or the template to avoid an error, eg.
{% if post.author_profile_photo %} {{ post.author_profile_photo }} {% else
%} {{ <placeholder image>}} {% endif %}
