editable = False — inline field validation in Django

Syntax

 field_name = models.Field (editable = False) 

Editing an inline field in Django editable = False explanation

Illustration editable = False using example. Consider a project named pythonengineering that has an application named geeks .

Refer to the following articles to check how to create a project and an app in Django.

• How to Create a Basic Project using MVT in Django?
• How to Create an App in Django?

Enter the following code into the models.py file of the geeks application. We will use CharField to experiment with all the margin variations.

from django.db import models from django.db.models import Model # Create your models here.    class GeeksModel (Model): geeks_field = models.CharField ( max_length = 200 ,    default = "GFG is best" ,  editable = False )

After running the make migrations and migrating to Django and rendering the above model, let’s try creating an instance from the Django admin interface. You can see that this field is not visible in the admin interface. Hit Save . 

Let’s check in the admin interface to see if the model has been instantiated. 

Therefore editable = False changes the field so that it is not visible to the admin interface.

Default Advanced Concepts

editable = False is usually used to hide some fields like encrypted code or email verification code etc. from admin panel ... To use editable fields, you must specify one of the following parameters:

• null = True and empty = True , so your field does not give required error while saving the model.
• default = value , this will also set the field to some value so that it does not cause suspicious errors for the administrator.
