Re: Django Admin: object history not working

[Ryan Kite]

Thanks for the clarification, I didn't realize it only applied to changes 
administered directly from the Django Admin. 
Was interested in learning about an objects' change history, but in this 
case, the changes were not performed from the Django Admin.

Django Admin: object history not working

[Ryan Kite]

Hello,

The issue is when clicking the "History" button on an object from the 
Django admin site, it opens to the template but says "*This object doesn't 
have a change history. It probably wasn't added via this admin site."*

>From reading the docs it appears that: *history_view*() already exists 
(which is what I want)

/// from the doc page: 
ModelAdmin.history_view(*request*, *object_id*, *extra_context=None*)
[source] 

¶ 


 Django view for the page that shows the modification history for a 
given model instance.

///

We can see the change history when doing:

 python manage.shell

import django.contrib.admin.models import LogEntry
from django.contrib.contenttypes.models import ContentType
from app import MyModel 

 results = 
LogEntry.objects.filter(content_type=ContentType.objects.get_for_model(MyModel 
))

print(vars(results[1])) 

.. shows the change details

Please tell me what I'm missing or need to add.

Re: Tables missing in SQLite but viewable in admin (confusion)

[Ryan Kite]

Thanks, Antonis, you were correct. The app was not actually using the 
SQLite DB it was using a different one that was not on the local machine.
