A series of class based view mixins.

Project description

Django Infuse

Series of Class based mixins. Requires Django 1.4s use of PermissionDenied exception.


pip install django-infuse

Currently Supported Mixins

* Permission Required
* Staff Required
* Super User required
* Login Required
* Group Required


### Login Required Mixin

Inherit the mixin you want to use and add any additional (optional) params.

from infuse.auth.permissions import LoginRequiredMixin

class MyLoginProtectedView(LoginRequiredMixin, ListView):
# If login_url is not the url you want to redirect
# users to, set one here.

login_url = "/my/new/url/"

# Do the rest of your stuff.....

### Group Required Mixin

The only other different one is GroupRequiredMixin

from infuse.auth.permissions import GroupRequiredMixin

class MyGroupRequiredView(GroupRequiredMixin, ListView):
# Uses login_required, so you can optionally pass in
# a url just like LoginRequired.

# You MUST set a group, Infuse will throw an exception
# if you do not.

group = "My Awesome Group"

### Permission Required Mixin

Original work by Kenneth Love and Chris Jones. Modified to always raise PermissionDenied

from infuse.auth.permissions import PermissionRequiredMixin

class PermissionRequiredView(PermissionRequiredMixin, ListView):
# Permission to require
permssion_required = 'model.can_do_something'

### Save and Continue Form Wizard

This mixin is still very much in a alpha status. The django form wizard does not support the concept of 'Finish Later' or any
built in ability to save the form 'half done'. This mixin provides a way for developers to add a 'Finish Later' functionality
to their form wizard.

In order to use the 'Finish Later' functionality you must add a button/input element on your form wizard templates and name it 'save_only'

<input type='submit' name='save_only' value='Finish Later'>

Next inherit the SaveAndContinue Mixin

from infuse.wizard.mixins import SaveAndContinueWizard

class MyFinishLaterWizard(SaveAndContinueWizard):

# This url is where the user will be redirected to when
# they click the 'Finish Later' button
save_only_url = reverse_lazy('wheretogowhenuserssaves')

In addition to the ``save_only_url`` that you are required to set, you may also provide the following methods:

def post_save_only(self):

def process_wizard_goto_step(self, wizard_goto_step):
if wizard_goto_step and wizard_goto_step in self.get_form_list(): = wizard_goto_step
form = self.get_form(,
return self.render(form)

def pre_process(self, form):

def additional_file_processing(self):

* ``post_save_only`` - Called when save_only is executed. Provides a way to hook into the save_only processor
* ``pre_process`` - Do any pre processing before forms are attempted to save. Can be used to setup formsets.
* ``additional_file_processing`` - Do any additional file processing. I use this to make sure that files saved to AWS are saved
with the correct file name.
* ``process_wizard_goto_step`` - Allows you to override the default behaviour of going between steps.

This particular mixin is extreamly powerful, but is in a constantly changing state. If you are using it, please provide some feedback of how and what your using it for, as well as any improvements you have.
