Creates a pg_dumpish output which masks data without saving changes to the source database.
Project description
Django Mask Postgres Data
Adds a management command to your Django project which allows you to create a (sort of) pg_dump of your data with sensitive data masked.
Installation
Install with pip:
pip install django-maskpostgresdata
And add maskpostgresdata
to your INSTALLED_APPS
:
INSTALLED_APPS = [
...
'maskpostgresdata',
...
]
Usage
By default, django-maskpostgresdata
will replace the password
column for each row in the Django User
model with "password". Just run manage.py dump_masked_data
and you'll get a pg_dump with the password field changed to "password" for all users.
There are 2 ways to customise the behaviour of django-maskpostgresdata
.
To override individual fields of a model with a given value, add a dictionary called MASKER_FIELDS
to your settings using the following format:
MASKER_FIELDS = {
"{ APP_NAME }": {"{ MODEL_NAME }": {"{ FIELD_NAME }": { VALUE },}},
}
Alternatively, you can define exactly how the data is updated by subclassing BasePostgresDataMaskingCommand
in a management command of your own. For example:
from django.contrib.auth.hashers import make_password
from maskpostgresdata import BasePostgresDataMaskingCommand
class Command(BasePostgresDataMaskingCommand):
def update_auth_user(self, queryset):
queryset.update(password=make_password("a_different_password"))
Just create a method called update_{ db_table_name }
taking a queryset
as the parameter. You can then perform update
operations on this queryset. { db_table_name }
is of the format {app_label}_{model_name}
by default, but could technically be different.
You can then run manage.py dump_masked_data
and it will dump your data to stdout
.
