.. BANNEREND

django-anon will help you anonymize your production database so it can be shared among developers, helping to reproduce bugs and make performance improvements in a production-like environment.

"🚀", "Really fast data anonymization and database operations using bulk updates to operate over huge tables" "🍰", "Flexible to use your own anonymization functions or external libraries like Faker <https://faker.readthedocs.io/en/latest/index.html>" "🐩", "Elegant solution following consolidated patterns from projects like Django <https://djangoproject.com/> and Factory Boy <https://factoryboy.readthedocs.io/en/latest/index.html>_" "🔨", "Powerful. It can be used on any projects, not only Django, not only Python. Really!"

.. end-introduction .. start-usage

Usage

Use anon.BaseAnonymizer to define your anonymizer classes:

.. code-block:: python

import anon

from your_app.models import Person

class PersonAnonymizer(anon.BaseAnonymizer): email = anon.fake_email

  # You can use static values instead of callables
  is_admin = False

  class Meta:
     model = Person

run anonymizer: be cautious, this will affect your current database!

PersonAnonymizer().run()

Built-in functions

.. code:: python

   import anon

   anon.fake_word(min_size=_min_word_size, max_size=20)
   anon.fake_text(max_size=255, max_diff_allowed=5, separator=' ')
   anon.fake_small_text(max_size=50)
   anon.fake_name(max_size=15)
   anon.fake_username(max_size=10, separator='')
   anon.fake_email(max_size=40, suffix='@example.com')
   anon.fake_url(max_size=50, scheme='http://', suffix='.com')
   anon.fake_phone_number(format='999-999-9999')


Lazy attributes
~~~~~~~~~~~~~~~

Lazy attributes can be defined as inline lambdas or methods, as shown below,
using the ``anon.lazy_attribute`` function/decorator.

.. code-block:: python

   import anon

   from your_app.models import Person

   class PersonAnonymizer(anon.BaseAnonymizer):
      name = anon.lazy_attribute(lambda o: 'x' * len(o.name))

      @lazy_attribute
      def date_of_birth(self):
         # keep year and month
         return self.date_of_birth.replace(day=1)

      class Meta:
         model = Person


The clean method
~~~~~~~~~~~~~~~~

.. code-block:: python

   import anon

   class UserAnonymizer(anon.BaseAnonymizer):
      class Meta:
         model = User

      def clean(self, obj):
         obj.set_password('test')
         obj.save()


Defining a custom QuerySet

A custom QuerySet can be used to select the rows that should be anonymized:

.. code-block:: python

import anon

from your_app.models import Person

class PersonAnonymizer(anon.BaseAnonymizer): email = anon.fake_email

  class Meta:
     model = Person

  def get_queryset(self):
     # keep admins unmodified
     return Person.objects.exclude(is_admin=True)

High-quality fake data

In order to be really fast, **django-anon** uses it's own algorithm to generate fake data. It is
really fast, but the generated data is not pretty. If you need something prettier in terms of data,
we suggest using `Faker <https://faker.readthedocs.io/en/latest/index.html>`_, which can be used
out-of-the-box as the below:

.. code-block:: python

   import anon

   from faker import Faker
   from your_app.models import Address

   faker = Faker()

   class PersonAnonymizer(anon.BaseAnonymizer):
      postalcode = faker.postalcode

      class Meta:
         model = Address

.. end-usage
