Latest changelog

0.12.0 - 2017-02-14

This is the cumulative release with many backward incompatibility changes.

  • Django 1.6 now longer supported.
  • Frontend now a part of the open-source package.
  • Flow chart visualization added
  • Every _cls suffix, ex in flow_cls, activation_cls, was renamed to _class. The reason for that is just to be consistent with django naming theme.
  • Django-Extra-Views integration is removed. This was a pretty creepy way to handle Formsets and Inlines within django class-based views. Instead, django-material introduce a new way to handle Form Inlines same as a standard form field. See details in the documentation.
  • Views are no longer inherits and implement an Activation interface. This change makes things much simple internally, and fixes inconsistency, in different scenarios. @flow_view, @flow_start_view decorators are no longer callable.
  • Activation now passed as a request attribute. You need to remove explicit activation parameter from view function signature, and use request.activation instead.
  • Built-in class based views are renamed, to be more consistent. Check the documentation to find a new view name.
  • If().OnTrue().OnFalse() renamed to If().Then().Else()
  • All conditions in If, Switch and other nodes receives now a node activation instance instead of process. So you can gen an access to the current task via activation.task variable.
  • Same for callable in the .Assign() and .Permissions definitions.
  • task_loader not is the attribute of a flow task. In makes functions and signal handlers reusable over different flows.
  • Flow namespace are no longer hardcoded. Flow views now can be attached to any namespace in a URL config.
  • flow_start_func, flow_start_signal decorators need to be used for the start nodes handlers. Decorators would establish a proper locking avoids concurrent flow process modifications in the background tasks.
  • To use celery job with django 1.8, django-transaction-hooks need to be enabled.
