Forgot to add template tags

backend/templatetags/perms.py

+from django import template
+from backend import const
+
+register = template.Library()
+
+@register.filter
+def editable_by(value, arg):
+    return value.can_be_edited(arg)
+
+@register.filter
+def is_admin(value):
+    # Make sure we work with an AM
+    if hasattr(value, "am_or_none"):
+        value = value.am_or_none
+    if value is None:
+        return False
+    return value.is_fd or value.is_dam
