Django Admin Dashboard problem with user permissions

Question

What can I do to prevent user w1 from selecting user q when creating the location? The uesr w1 has all the rights to create the models and has staff status. Is there a way that the user w1 is written directly into the field "user" without the user w1 having to do this manually?

code: models.py and admin.py https://www.codepile.net/pile/QmA9awmV
