django.utils.safestring SafeData Example Code

SafeData is a class within the django.utils.safestring module of the Django project.

Example 1 from django-angular

django-angular (project examples website) is a library with helper code to make it easier to use Angular as the front-end to Django projects. The code for django-angular is open source under the MIT license.

Example 2 from django-rest-framework

Django REST Framework (project homepage and documentation, PyPI package information and more resources on Full Stack Python), often abbreviated as "DRF", is a popular Django extension for building web APIs. The project has fantastic documentation and a wonderful quickstart that serve as examples of how to make it easier for newcomers to get started.

The project is open sourced under the Encode OSS Ltd. license.

Example 3 from django-tables2

django-tables2 (projection documentation and PyPI page) is a code library for Django that simplifies creating and displaying tables in Django templates, especially with more advanced features such as pagination and sorting. The project and its code are available as open source.
