Sniff your django models to look for any data issues

Project description


django-data-sniffer provides a set of tools to inspect the data in your service for misconfigurations


  • Configurable warning/alert queries on any database table in your django app
  • A view to see all misconfigured objects in your table
  • Ability to modify your queries via an externally hosted manifest file so that adding a new health check doesn't require a deployment

Coming Soon

  • Filters & grouping
  • Search
  • Pagination
  • Get manifest file from util method instead of URL
  • JSON API response
  • Notifications



pip install django_data_sniffer
