How to Display readonly_fields in Admin in Django

In this article, we show how to display readonly_fields in admin in Django.

By default, fields marked as 'editable= False' will not show up in admin.

However, there still is a way that you can display them without changing 'editable= False'

The way to do so is to create a ModelAdmin in which you can display readonly_fields.

So, examples of fields that are readonly_fields are DateTimeField(s).

These fields cannot be seen unless you explicitly write code that makes them seeable.

So this is what we're going to do in this page.

As an example, we'll create a simple database table called MemberComment. This database table will have 3 fields: comment, timestamp (for when the comment was submitted), and updated (for when it was last updated).

This is shown below.

models.py File

from django.db import models class MemberComment(models.Model): comment= models.TextField() timestamp = models.DateTimeField(auto_now_add= True) updated= models.DateTimeField(auto_now= True)

By default, timestamp and updated are marked 'editable= False', so they will not show up by default in admin.

So what we have to do is go into the admin.py file and create a ModelAdmin for the database table.

We then can render out readonly_fields.

We can register these fields into admin in the admin.py page, using the following code.

from django.contrib import admin from .models import MemberComment class MemberCommentAdmin(admin.ModelAdmin): fields= [ 'comment', 'updated', 'timestamp', ] readonly_fields= ['updated', 'timestamp',] class Meta: model= MemberComment

Once you register it, you will see the following output, shown below.

And this is how readonly_fields can be displayed in admin in Django.
