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): pass def process_wizard_goto_step(self, wizard_goto_step): if wizard_goto_step and wizard_goto_step in self.get_form_list(): self.storage.current_step = wizard_goto_step form = self.get_form( data=self.storage.get_step_data(self.steps.current), files=self.storage.get_step_files(self.steps.current)) return self.render(form) def pre_process(self, form): pass def additional_file_processing(self): pass
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.
