How do I hide Unit_attribute object (3) from the admin display?

In my Django admin UI I use a TabularInline like this:

I used django-comment-system
I want import classadmin from admin.py (that in my app project) at admin.py (that in LIB/site-packages/comment)

I have such models:

I have filters for year_record, age_category, and malnutrition_category. I want the default data shown in my Django admin UI list to correspond to the first value in each filter list. Additional data should only appear when filters are applied or when searching

I have pretty large list of objects so I would like to move the “save” button in the Django admin panel to the top of the list of objects, rather than the bottom.

I need to add custom file upload handler in admin add and change view (using django 3.2). And getting an error.

I’m developing a django app. I wish to change the admin url with an environment variable.

Recently, i cloned a project from github to get more familiar with projects written in Django. Previously, everything was running fine, but today when i tried to sign into the Django admin page it gave me this error:

I’m having a weird problem where normally field_val should be set to some particular value but is being set to “”. When I debug in vscode and look into the value from the debugger, inspecting it (possibly triggering something), suddenly the variable becomes available. When I’m not debugging the value is empty string. I couldn’t understand what’s happening here. Is there some kind of lazy evaluation that I’m missing in django forms?
