How to implement modules to reuse Python/Django code?

Question

Django

Hello, please help me understand.
I am writing an application for the sake of interest and practice, a small social network in Python 3.4 - Django 1.7
As always and everywhere in the social. networks have:
User page:
- Photos
- Videos
- Wall with comments
Communities:
- Photos
- Videos
- Wall with comments
- Discussions where there is a question and answers to them in the form of comments
Photos have their own comments, videos have their own comments
. For example, the functionality of photos - adding / deleting / editing / outputting - is the same everywhere on the user's page, in the community
. Also, all comments have the same functionality.
Of course, you can create for all comments, photos, videos on 1 table where there will be item_id and app_label fields,
item_id - the identifier of the owned record
app_label - the application to which the record belongs to
do for each application view - adding / deleting, etc., which will accept item_id and app_label to use them everywhere.
This option, I think, will be a little wrong, since the tables will be too clogged.
I would like each application to have its own tables in the database, for example:
user_page_comments
user_photo_comments
user_video_comments
community_comments
community_photo_comments
...
but there was only one code responsible for business logic.
Do you have any ideas?

In my opinion, in your case, generic relations is the very thing.
