===========================================
Quagga: the extinct Zebra (just as Stripey)
===========================================

Zebra is a library that makes using Stripe with Django even easier.

Quagga is a fork of the original Django Zebra library. See the note on
compatibility below.

.. image:: https://github.com/bennylope/django-quagga/raw/master/quagga.jpg

It's made of:

* `zebra`, the core library, with forms, webhook handlers, abstract models,
  mixins, signals, and templatetags that cover most stripe implementations.
* `marty`, an example app for how to integrate zebra, that also serves as its test suite.

Pull requests are quite welcome!

**Note (2016)**: this fork is maintained solely to maintain compatability between existing
functionality and current versions of Django.

Usage
=====

Installation
------------

1. `pip install django-quagga`

2. Edit your `settings.py`::

    INSTALLED_APPS += ("zebra",)
    STRIPE_SECRET = "YOUR-SECRET-API-KEY"
    STRIPE_PUBLISHABLE = "YOUR-PUBLISHABLE-API-KEY"
    # Set any optional settings (below)

3. (optional) `./manage.py migrate` if you have `ZEBRA_ENABLE_APP = True`

4. (optional) Add in the webhook urls::

    urlpatterns += [
        url(r'zebra/', include('zebra.urls',  namespace="zebra",  app_name='zebra')),
    ]

5. Enjoy easy billing.


Optional Settings
-----------------

* `ZEBRA_ENABLE_APP`
    Defaults to `False`.  Enables Customer, Plan, and Subscription django
    models, as a part of zebra.
* `ZEBRA_CUSTOMER_MODEL`
    The app+model string for the model that implements the StripeCustomerMixin.
    ie `"myapp.MyCustomer"`.  If `ZEBRA_ENABLE_APP` is true, defaults to
    `"zebra.Customer"`.
* `ZEBRA_AUTO_CREATE_STRIPE_CUSTOMERS`
    Defaults to `True`.  Automatically creates a stripe customer object on
    stripe_customer access, if one doesn't exist.

Webhooks
========

Zebra handles all the webhooks that stripe sends back and calls a set of
signals that you can plug your app into.  To use the webhooks:

* Include the zebra urls
* Update your stripe account to point to your webhook URL (aka
  https://www.mysite.com/zebra/webhooks)
* Plug into any webhook signals you care about.

**Note: The initial Stripe webhook system is being deprecated. See below for a
description of Zebra's support for the new system.**

Zebra provides:

* `zebra_webhook_recurring_payment_failed`
* `zebra_webhook_invoice_ready`
* `zebra_webhook_recurring_payment_succeeded`
* `zebra_webhook_subscription_trial_ending`
* `zebra_webhook_subscription_final_payment_attempt_failed`

All of the webhooks provide the same arguments:

* `customer` - if `ZEBRA_CUSTOMER_MODEL` is set, returns an instance that
  matches the `stripe_customer_id`, or `None`.  If `ZEBRA_CUSTOMER_MODEL` is
  not set, returns `None`.
* `full_json` - the full json response, parsed with simplejson.

So, for example, to update the customer's new billing date after a successful
payment, you could:

(assuming you've set `ZEBRA_CUSTOMER_MODEL` or are using `ZEBRA_ENABLE_APP`)::

    from zebra.signals import zebra_webhook_recurring_payment_succeeded

    def update_last_invoice_date(sender, **kwargs):
        customer = kwargs.pop("customer", None)
        full_json = kwargs.pop("full_json", None)
        customer.billing_date = full_json.date
        customer.save()

    zebra_webhook_recurring_payment_succeeded.connect(update_last_invoice_date)

Webhooks Update
---------------

Stripe recently updated their webhook implementation (see
https://stripe.com/blog/webhooks). Zebra includes an implementation of the new
system.

* Include the zebra urls
* Update your stripe account to point to your webhook URL (aka
  https://www.mysite.com/zebra/webhooks/v2/)
* Plug into any webhook signals you care about.

Zebra provides:

* `zebra_webhook_charge_succeeded`
* `zebra_webhook_charge_failed`
* `zebra_webhook_charge_refunded`
* `zebra_webhook_charge_disputed`
* `zebra_webhook_customer_created`
* `zebra_webhook_customer_updated`
* `zebra_webhook_customer_deleted`
* `zebra_webhook_customer_subscription_created`
* `zebra_webhook_customer_subscription_updated`
* `zebra_webhook_customer_subscription_deleted`
* `zebra_webhook_customer_subscription_trial_will_end`
* `zebra_webhook_customer_discount_created`
* `zebra_webhook_customer_discount_updated`
* `zebra_webhook_customer_discount_deleted`
* `zebra_webhook_invoice_created`
* `zebra_webhook_invoice_updated`
* `zebra_webhook_invoice_payment_succeeded`
* `zebra_webhook_invoice_payment_failed`
* `zebra_webhook_invoiceitem_created`
* `zebra_webhook_invoiceitem_updated`
* `zebra_webhook_invoiceitem_deleted`
* `zebra_webhook_plan_created`
* `zebra_webhook_plan_updated`
* `zebra_webhook_plan_deleted`
* `zebra_webhook_coupon_created`
* `zebra_webhook_coupon_updated`
* `zebra_webhook_coupon_deleted`
* `zebra_webhook_transfer_created`
* `zebra_webhook_transfer_failed`
* `zebra_webhook_ping`

Zebra also provides an easy map of all the signals as
`zebra.signals.WEBHOOK_MAP`, which maps events (`charge_succeeded`) to the
Zebra signal (`zebra_webhook_charge_succeeded`). To assign a handler to all the
signals that zebra sends, for example, loop over the items in the map::

    for event_key, webhook_signal in WEBHOOK_MAP.items():
        webhook_signal.connect(webhook_logger)

Forms
=====

The StripePaymentForm sets up a form with fields like [the official stripe
example](https://gist.github.com/1204718#file_stripe_tutorial_page.html).

In particular, the form is stripped of the name attribute for any of the credit
card fields, to prevent accidental submission. Media is also provided to set up
stripe.js (it assumes you have jQuery).

Use it in a view like so::

    if request.method == 'POST':
        zebra_form = StripePaymentForm(request.POST)
        if zebra_form.is_valid():
            my_profile = request.user.get_profile()
            stripe_customer = stripe.Customer.retrieve(my_profile.stripe_customer_id)
            stripe_customer.card = zebra_form.cleaned_data['stripe_token']
            stripe_customer.save()

            my_profile.last_4_digits = zebra_form.cleaned_data['last_4_digits']
            my_profile.stripe_customer_id = stripe_customer.id
            my_profile.save()

            # Do something kind for the user

    else:
        zebra_form = StripePaymentForm()

Template Tags
=============

There are a couple of template tags that take care of setting up the stripe
env, and rendering a basic cc update form.  Note that it's expected your
`StripePaymentForm` is called either `zebra_form` or `form`.

To use in a template::

    {% extends "base.html" %}{% load zebra_tags %}

    {% block head %}{{block.super}}
        {% zebra_head_and_stripe_key %}
    {% endblock %}

    {% block content %}
        {% zebra_card_form %}
    {% endblock %}

That's it - all the stripe tokeny goodness happens, and errors are displayed to
your users.

Models and Mixins
=================

Model and Mixin docs coming.  For now, the code is pretty self-explanatory, and
decently documented inline.

Other Useful Bits
=================

Zebra comes with a manage.py command to clear out all the test customers from
your account.

To use it, run::

    ./manage.py clear_stripe_test_customers

It responds to `--verbosity=[0-3]`.

Credits
=======

I did not write any of stripe. It just makes me happy to use, and inspired to
make better APIs for my users. For Stripe info, ask them:
