Display custom format name on django admin page

I want to display first name and last name. To achieve that, I have used __str__() method. But it is not working. 

class OnlineUser(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)

    def __str__(self):
        return f"{self.user.first_name} {self.user.last_name}"

Instead it display, user ID.

In admin.py,

class OnlineUsersAdmin(admin.ModelAdmin):
    # a list of displayed columns name.
    list_display=['user']

admin.site.register(OnlineUsers, OnlineUsersAdmin)

Where I'm doing wrong? How to get the format I want?

Version:

Django==2.0.1

Debug:

user_info=OnlineUsers.objects.get_or_create(user=self.user)
print(user_info.__str__())

Output:

((<OnlineUsers: FIRST_NAME LAST_NAME >, False))

Here, inside return you can return only str + str, not str + int. So, you have to convert every int to str

from django.db import models

# Create your models here.


class Fabonacci(models.Model):
    numstr = models.IntegerField()
    terms = models.CharField(max_length=500)

    def __str__(self):
        return "The first " + str(self.numstr) + " terms in fibonacci series : " + self.terms

The list_display--(Django doc) support callable methods too. So, define a user(...) method on Model admin as,

class OnlineUsersAdmin(admin.ModelAdmin):
    # a list of displayed columns name.
    list_display = ['user']

    def user(self, instance):
        return instance.__str__()

You should use __str__ instead of user in list_display:

list_display=['__str__']

Otherwise you tell django to show user field. And since User model doen't have overrided __str__ method you see user's id.

Also you can just remove list_display attribute. In this case __str__ will be used by default.
