Making a field in a django admin form visible or invisible depending on the user

While i was working on the project onspot_v2, i came across with a specific need. onspot_v2 makes use of the django admin interface for data entry. When employees are entering data, ‘branch’ field in the form will get populated automatically as per the branch of the employee. When a manager is entering data using the form, an extra field should appear to select the ‘branch’ instead of automatically populating. Googling didn’t help much. Finally i thought of overriding the ModelAdmin.add_view() method which is invoked when you try to add an entry using the admin. I changed the editable property of the field ‘branch’ inside after checking the request.user and it worked out. Part of my code in admin.py

from django.contrib import admin
from books.models import Agent, PolicyIssue

class PolicyIssueAdmin(admin.ModelAdmin):
 
    def add_view(self, request, form_url='', extra_context=None):
        if request.user.get_profile().is_employee:
            self.model.branch.field.editable = False
        else:
            self.model.branch.field.editable = True
        return super(PolicyIssueAdmin, self).add_view(request, form_url)

admin.site.register(PolicyIssue, PolicyIssueAdmin)
