django-fsm-admin
================
Mixin and template tags to integrate django-fsm_ state transitions into the
Django Admin.
Installation
------------
.. code:: sh
$ pip install django-fsm-admin
Or from GitHub:
.. code:: sh
$ pip install -e git://github.com/gadventures/django-fsm-admin.git#egg=django-fsm-admin
Usage
-----
1. Add ``fsm_admin`` to your ``INSTALLED_APPS``.
2. Ensure that you have ``"django.core.context_processors.request"`` in your
``TEMPLATE_CONTEXT_PROCESSORS`` in Django settings. If the setting variable
is not yet defined, add:
.. code:: python
from django.conf import settings
TEMPLATE_CONTEXT_PROCESSORS = settings.TEMPLATE_CONTEXT_PROCESSORS + (
"django.core.context_processors.request",
)
3. In your ``admin.py`` file, use ``FSMTransitionMixin`` to add behaviour to your
ModelAdmin. ``FSMTransitionMixin`` 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``.
.. code:: python
from fsm_admin.mixins import FSMTransitionMixin
class YourModelAdmin(FSMTransitionMixin, admin.ModelAdmin):
# The name of one or more FSMFields on the model to transition
fsm_field = ['wf_state',]
admin.site.register(YourModel, YourModelAdmin)
4. 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.
.. code:: python
@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.
.. code:: python
@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.
