unpoly-django 0.1.0

An app for Django to implement the Unpoly v2 Server Protocol

django-unpoly

What it does

unpoly is a reusable app for Django implementing a Django-flavored Unpoly v2 Server Protocol.

It provides:

1. A middleware which adds is_unpoly unpoly_target, and unpoly_validate methods to the request object.

2. A view mixin classes support both Django Generic Views and Vanilla Views.

3. A Form mixin class for Crispy Forms.

Installation

pip install unpoly_django

Configuration

You need to add unpoly.middleware.UnpolyMiddleware to your MIDDLEWARE.

To install all the middleware, you want something like:

MIDDLEWARE = (
    # ...
    'unpoly.middleware.UnpolyMiddleware',
    # ...
)

Settings

If using the View mixins following constants to settings.py:

MAIN_UP_TARGET = '#your_main_up_target'
MAIN_UP_FAIL_TARGET = '#your_main_upfail_target'

DEFAULT_UP_ERROR_TEMPLATE = 'your-unpoly-error-template.html'

# Default Templates for various Unpoly layers.
# Override on individual View attributes.
UNPOLY_MODAL_TEMPLATE = 'your-unpoly-modal-template.html'
UNPOLY_DRAWER_TEMPLATE = 'your-unpoly-drawer-template.html'
UNPOLY_POPUP_TEMPLATE = 'your-unpoly-popup-template.html'
UNPOLY_COVER_TEMPLATE = 'your-unpoly-cover-template.html'

# Routing URL kwarg set when an optimized response is to be sent
OPTIMIZED_SUCCESS_RESPONSE = 'optimized_success_response'

DEFAULT_ERROR_VIEW = 'appname:error_view_name'

CSRF Token

Ensure that the csrf_token meta tag is included in the head section of your templates

<meta name="csrf-token" content="{{ csrf_token }}" />

View Mixins

View mixin classes add hooks and properties for sending optimized server responses to the frontend.

Add view mixin classes to Django's Generic views, or Vanilla Views:

from django.views.generic import FormView, TemplateView
from unpoly.views import UnpolyViewMixin, UnpolyFormViewMixin, UnpolyCrispyFormViewMixin


class YourTemplateView(UnpolyViewMixin, TemplateView):
    pass

class YourFormView(UnpolyViewMixin, FormView):
    pass

class YourCrispyFormView(UnpolyCrispyFormViewMixin, FormView):
    pass

Crispy Form Mixin

The Crispy Form mixin can be used when form mixins are used, which enables passing up-target, up-layer, up-fail-layer and up-fail-target params from views to forms:

from django.forms import ModelForm
from unpoly.forms import UnpolyCrispyFormMixin

class UnpolyCrispyForm(UnpolyCrispyFormMixin, ModelForm):
    pass
