GitHub logo rcrowther / django-streamfield-w

A StreamField for Django. Ported from Wagtail, with new DjangoAdmin-like API.

StreamField

A Streamfield for Django. Saves data as JSON to the referenced field. The admin display is designed to operate unobtrusively and be styled as the stock Django Admin.

The distribution is called 'django-streamfield-w', but internally the module is called 'streamfield'.

Pros

  • It's a StreamField
  • Written data should be Wagtail-compatible (mostly, no guarantee)

Cons

  • No file or image handling (unless you implement from another app)
  • Small but scenery-chewing admin

And an admission: anything that works here has needed code reduction, code expansion, and/or hacks. There are still many possibilities for work within the programmer API. So this codebase will not be solid anytime soon, and lacks tests on code, app, and distribution. Best I can say is that I have outlined the functionality.

Examples

Want to give a user the ability to add blocks of text, interspaced with blockquotes, URL links and dates? Declare this field,

body = StreamField(
    block_types

Mask your objects instead of deleting them from your database.

Django safedelete

https://travis-ci.org/makinacorpus/django-safedelete.png https://coveralls.io/repos/makinacorpus/django-safedelete/badge.png

What is it ?

For various reasons, you may want to avoid deleting objects from your database.

This Django application provides an abstract model, that allows you to transparently retrieve or delete your objects without having them deleted from your database.

You can choose what happens when you delete an object :
  • it can be masked from your database (soft delete, the default behavior)
  • it can be masked from your database and mask any dependent models. (cascading soft delete)
  • it can be normally deleted (hard delete)
  • it can be hard-deleted, but if its deletion would delete other objects, it will only be masked
  • it can be never deleted or masked from your database (no delete, use with caution)

Example

# imports
from safedelete.models import SafeDeleteModel
from safedelete.models import HARD_DELETE_NOCASCADE
# Models

# We create a new model, with the given policy : Objects will
