The easiest way to create read-only models

Installation

Install using pip:

pip install django-readonly-model

Add 'readonly_model' to your INSTALLED_APPS setting:

INSTALLED_APPS = [
    ...
    'readonly_model',
]

Example

Declare a model to read:

from django.db import models

class Directory(models.Model):
    class Meta:
        read_only_model = True

We can read data from the model but we cannot write:

>>> from app.models import Directory
>>> Directory.objects.count()
0
>>> Directory.objects.create(name='kg')
...
readonly_model.exceptions.ReadOnlyModel: Model 'app.models.Directory' is read-only

You cannot write but you can load data from fixtures:

$ python3 manage.py loaddata fixtures/directory.json

>>> from app.models import Directory
>>> Directory.objects.count()
3

When is it needed?

• When you want to protect the model from accidental recording.

• When you have some data that cannot be changed programmatically (for example, various directories).

• When you need to use a read-only model from a database that you cannot write to it.
