Django Users as choices in another model

Using Django Forms & APIs

Django 5.1.1
Python 3.12.4

I need to get all the Django username’s and use them as a choice field in model . I generally use
user = request.user to get a user’s information but I need all users and use them in a choice class

class ManagerMessages(models.Model):
   class UserChoices(models.TextChoices):
           *Not sure what to put here*

    UserName= models.CharField(max_length=10, choices=UserChoices.choices)

Actually, the appropriate option here would be to change that field to be a ForeignKey to your User model.

Quoting directly from the Django docs for choices at: Model field reference | Django documentation | Django

Note that choices can be any sequence object – not necessarily a list or tuple. This lets you construct choices dynamically. But if you find yourself hacking choices to be dynamic, you’re probably better off using a proper database table with a ForeignKey. choices is meant for static data that doesn’t change much, if ever.
