Installation

$ pip install django-fsm-wagtail

Or from GitHub:

$ pip install -e git://github.com/abahnihi/django-fsm-wagtail.git#egg=django-fsm-wagtail

Usage

1. Add fsm_wagtail to your INSTALLED_APPS.

from django.conf import settings

TEMPLATE_CONTEXT_PROCESSORS = settings.TEMPLATE_CONTEXT_PROCESSORS + (
    "django.core.context_processors.request",
)

2. In your admin.py file, use FsmWagtailAdminMixin to add behaviour to your ModelAdmin. You can remove ModelAdmin or FsmWagtailAdminMixin should be before ModelAdmin, the order is important.

It assumes that your workflow state field is named state, however you can override it or add additional workflow state fields with the attribute fsm_field.

from fsm_wagtail.admin import FsmWagtailAdminMixin

class YourModelAdmin(FsmWagtailAdminMixin):
    # The name of one or more FSMFields on the model to transition
    fsm_field = ['wf_state',]

3. By adding custom=dict(admin=False) to the transition decorator, one can disallow a transition to show up in the admin interface. This specially is useful, if the transition method accepts parameters without default values, since in django-fsm-admin no arguments can be passed into the transition method.

@transition(
   field='state',
   source=['startstate'],
   target='finalstate',
   custom=dict(admin=False),
)
def do_something(self, param):
   # will not add a button "Do Something" to your admin model interface

By adding FSM_ADMIN_FORCE_PERMIT = True to your configuration settings, the above restriction becomes the default. Then one must explicitly allow that a transition method shows up in the admin interface.

@transition(
    field='state',
    source=['startstate'],
    target='finalstate',
    custom=dict(admin=True),
)
def proceed(self):
    # will add a button "Proceed" to your admin model interface

This is useful, if most of your state transitions are handled by other means, such as external events communicating with the API of your application.
