Django User' object is not iterable or not serializable

Question

I am new in Django I have this function in views.py

def edituser(request, id):
    member = User.objects.get(id=id)
    return JsonResponse(member, safe=False)

i have the error: Object of type User is not JSON serializable

How can i solve to return User values to javascript ajax function ?

If you want a list of one object, use `[x]`, not `list(x)`. (I don't see _why_ you would want a list in this case though, as it's guaranteed to have one one item...) — John Gordon, Mar 13 '23 at 01:05
json only knowns about basic data types: integer, string, float, list, dict, etc. It doesn't know how to convert custom classes. — John Gordon, Mar 13 '23 at 01:07
you means: member = [User.objects.get(id=id)] ? This doesn't work too — Amedeo De Longis, Mar 13 '23 at 01:09
It fixed the "Django User object is not iterable" error, which is all I intended. (But again, you have not said _why_ you wuld want a list of one item...) — John Gordon, Mar 13 '23 at 01:13
I don't want a list i am only trying to return the User values — Amedeo De Longis, Mar 13 '23 at 01:18
_I don't want a list_ Then it's quite surprising that you tried to use `list()`... — John Gordon, Mar 13 '23 at 01:19
ok let's forget the list. How can i return User values and solve the issue of Object of type User is not JSON serializable ? — Amedeo De Longis, Mar 13 '23 at 01:25

I think that the answer is here: https://linuxpip.org/object-of-type-is-not-json-serializable/ since the User object IS and/or contains non-serializables values, let's call them "this object contains a thing that have not a Javascript equivalent" check if you have an attribute out of the table in the link provided, to solve this maybe you should filter the "User" object using json.JSONEncoder

If you know the attributes that you want to return from the User object, you could construct a dictionary of those specific attributes:

def edituser(request, id):
    member = User.objects.get(id=id)
    member_dict = {
        "id": member.id,
        "name": member.name,
        "email": member.email,
        # etc...
    }
    return JsonResponse(member_dict, safe=False)
