Is there a way to concatenate 2 model field names in the "list display" to display as one column in Django Admin?

Question

In the Django Admin area, rather than have two separate columns for first_name and last_name to display, I'd like to concatenate those to create one column.

I want to avoid creating a separate model field to get this done. One solution could be to return self, but that seems to not work either.

The code below gets me "This site cannot be reached."

admin.py

from django.contrib import admin
from .models import Agent

class RealtorAdmin(admin.ModelAdmin):
  list_display = ('MLS_number', 'first_name' + 'last_name', 'email', 'phone', 'hire_Date')

See [this question](https://stackoverflow.com/questions/9164610/custom-columns-using-django-admin) for more examples. — Lord Elrond, Sep 12 '19 at 18:53

You can define a property in the model :

class Agent(models.Model):
    first_name = models.CharField(max_length=50)
    last_name = models.CharField(max_length=50)

    @property
    def fullname(self):
        return '{} {}'.format(self.first_name, self.last_name)
        # return f'{self.first_name} {self.last_name}'  # with python 3.6+

And then call it in the fields :

class RealtorAdmin(admin.ModelAdmin):
  list_display = ('MLS_number', 'fullname', 'email', 'phone', 'hire_Date')

@CalebGoodman, yep it's a clear and usefull syntax, but sadly not available in every versions of python. Thanks for the suggestion ;-) – PRMoureu Sep 12 '19 at 18:57
YW. I'm just a bit tilted that you beat me to the answer :) – Lord Elrond Sep 12 '19 at 18:59
@CalebGoodman Many answers is not a bad thing if each one brings something (even slightly) different – PRMoureu Sep 12 '19 at 19:01

Either define it as a property or method on the model, as PRMoureu showed, or define it directly on the ModelAdmin class:

class RealtorAdmin(admin.ModelAdmin):
  list_display = ('MLS_number', 'full_name', 'email', 'phone', 'hire_Date')

  def full_name(self, obj):
    return '{} {}'.format(obj.first_name, obj.last_name)

This is better if the admin is the only place you'll use this; otherwise the model is more appropriate.
