Quickstart
----------

Install dj-stripe:

.. code-block:: bash

pip install dj-stripe

Add ``djstripe`` to your ``INSTALLED_APPS``:

.. code-block:: python

INSTALLED_APPS =(
...
"djstripe",
...
)

Add your Stripe keys and set the operating mode:

.. code-block:: python

STRIPE_LIVE_PUBLIC_KEY = os.environ.get("STRIPE_LIVE_PUBLIC_KEY", "<your publishable key>")
STRIPE_LIVE_SECRET_KEY = os.environ.get("STRIPE_LIVE_SECRET_KEY", "<your secret key>")
STRIPE_TEST_PUBLIC_KEY = os.environ.get("STRIPE_TEST_PUBLIC_KEY", "<your publishable key>")
STRIPE_TEST_SECRET_KEY = os.environ.get("STRIPE_TEST_SECRET_KEY", "<your secret key>")
STRIPE_LIVE_MODE = <True or False>

Add some payment plans via the Stripe.com dashboard or the django ORM.

Add to the urls.py:

.. code-block:: python

url(r'^payments/', include('djstripe.urls', namespace="djstripe")),

Then tell Stripe about the webhook (Stripe webhook docs can be found `here <https://stripe.com/docs/webhooks>`_) using the full URL of your endpoint from the urls.py step above (e.g. ``https://yourwebsite.com/payments/webhook``).

Run the commands::

python manage.py migrate

python manage.py djstripe_init_customers


Running the Tests
------------------

Assuming the tests are run against PostgreSQL::

createdb djstripe
pip install tox

History
=======

- Updated Subscription.cancel() for compatibility with Stripe 2018-08-23 (#723)


1.2.2 (2018-08-11)
------------------

This is a bugfix-only version:

- Fixed an error with request.urlconf in some setups (#562)
- Always save text-type fields as empty strings in db instead of null (#713)
- Fix support for DJSTRIPE_SUBSCRIBER_MODEL_MIGRATION_DEPENDENCY (#707)
- Fix reactivate() with Stripe API 2018-02-28 and above

This is a bugfix-only version:

- Fixed various Python 2.7 compatibility issues
- Fixed issues with max_length of receipt_number
- Fixed various fields incorrectly marked as required
- Handle product webhook calls
- Fix compatibility with stripe-python 2.0.0


1.2.0 (2018-06-11)
------------------

The dj-stripe 1.2.0 release resets all migrations.

**Do not upgrade to 1.2.0 directly from 1.0.1 or below.
You must upgrade to 1.1.0 first.**

Please read the 1.1.0 release notes below for more information.


1.1.0 (2018-06-11)
------------------

In dj-stripe 1.1.0, we made a *lot* of changes to models in order to
bring the dj-stripe model state much closer to the upstream API objects.
If you are a current user of dj-stripe, you will most likely have to
make changes in order to upgrade. Please read the full changelog below.
If you are having trouble upgrading, you may ask for help `by filing an
issue on GitHub`_.

Upgrade notes
-------------

Migration reset
~~~~~~~~~~~~~~~

The next version of dj-stripe, **1.2.0**, will reset all the migrations
to ``0001_initial``. Migrations are currently in an unmaintainable
state.

**What this means is you will not be able to upgrade directly to
dj-stripe 1.2.0. You must go through 1.1.0 first, run
``manage.py migrate djstripe``, then upgrade to 1.2.0.**

Python 2.7 end-of-life
~~~~~~~~~~~~~~~~~~~~~~

dj-stripe 1.1.0 drops support for Django 1.10 and adds support for
Django 2.0. Django 1.11+ and Python 2.7+ or 3.4+ are required.

Support for Python versions older than 3.5, and Django versions older
than 2.0, will be dropped in dj-stripe 1.3.0.

Backwards-incompatible changes and deprecations
-----------------------------------------------

Removal of polymorphic models
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

The model architecture of dj-stripe has been simplified. Polymorphic
models have been dropped and the old base StripeCustomer, StripeCharge,
StripeInvoice, etc models have all been merged into the top-level
Customer, Charge, Invoice, etc models.

Importing those legacy models from ``djstripe.stripe_objects`` will
yield the new ones. This is deprecated and support for this will be
dropped in dj-stripe 1.3.0.

Full support for Stripe Sources (Support for v3 stripe.js)
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~

Stripe sources (``src_XXXX``) are objects that can arbitrarily reference
any of the payment method types that Stripe supports. However, the
legacy ``Card`` object (with object IDs like ``card_XXXX`` or
``cc_XXXX``) is not a Source object, and cannot be turned into a Source
object at this time. In order to support both Card and Source objects in
ForeignKeys, a new model ``PaymentMethod`` has been devised. That model
can resolve into a Card, a Source, or a BankAccount object.

- **The ``default_source`` attribute on ``Customer`` now refers to a
``PaymentMethod`` object**. You will need to call ``.resolve()`` on
it to get the Card or Source in question.
- References to ``Customer.sources`` expecting a queryset of Card
objects should be updated to ``Customer.legacy_cards``.
- The legacy ``StripeSource`` name refers to the ``Card`` model. This
will be removed in dj-stripe 1.3.0. Update your references to either
``Card`` or ``Source``.
- ``enums.SourceType`` has been renamed to ``enums.LegacySourceType``.
``enums.SourceType`` now refers to the actual Stripe Source types
enum.

Core fields renamed
~~~~~~~~~~~~~~~~~~~

- The numeric ``id`` field has been renamed to ``djstripe_id``. This
avoids a clash with the upstream stripe id. Accessing ``.id`` is
deprecated and \**will reference the upstream ``stripe_id`` in
dj-stripe 1.3.0

.. _by filing an issue on GitHub: https://github.com/dj-stripe/dj-stripe/issues


1.0.0 (2017-08-12)
------------------

It's finally here! We've made significant changes to the codebase and are
now compliant with stripe API version **2017-06-05**.

I want to give a huge thanks to all of our contributors for their help
in making this happen, especially Bill Huneke (@wahuneke) for his
impressive design work and @jleclanche for really pushing this release along.

I also want to welcome onboard two more maintainers, @jleclanche and @lskillen.
They've stepped up and have graciously dedicated their resources to making dj-stripe
such an amazing package.

Almost all methods now mimic the parameters of those same methods in the
stripe API. Note that some methods do not have some parameters
implemented. This is intentional. That being said, expect all method
signatures to be different than those in previous versions of dj-stripe.

Finally, please note that there is still a bit of work ahead of us. Not everything
in the Stripe API is currently supported by dj-stripe -- we're working on it.
That said, v1.0.0 has been thoroughly tested and is verified stable in
production applications.

A few things to get excited for
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- Multiple subscription support (finally)
- Multiple sources support (currently limited to Cards)
- Idempotency support (See #455, #460 for discussion -- big thanks to
@jleclanche)
- Full model documentation
- Objects that come through webhooks are now tied to the API version
set in dj-stripe. No more errors if dj-stripe falls behind the newest
stripe API version.
- Any create/update action on an object automatically syncs the object.
- Concurrent LIVE and TEST mode support (Thanks to @jleclanche). Note
that you'll run into issues if ``livemode`` isn't set on your
existing customer objects.
- All choices are now enum-based (Thanks @jleclanche, See #520). Access
them from the new ``djstripe.enums`` module. The ability to check
against model property based choices will be deprecated in 1.1
- Support for the Coupon model, and coupons on Customer objects.
- Support for the `Payout/Transfer
split <https://stripe.com/docs/transfer-payout-split>`__ from api
version ``2017-04-06``.

What still needs to be done (in v1.1.0)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- **Documentation**. Our original documentation was not very helpful,
but it covered the important bits. It will be very out of date after
this update and will need to be rewritten. If you feel like helping,
we could use all the help we can get to get this pushed out asap.
- **Master sync re-write**. This sounds scary, but really isn't. The
current management methods run sync methods on Customer that aren't
very helpful and are due for removal. My plan is to write something
that first updates local data (via ``api_retrieve`` and
``sync_from_stripe_data``) and then pulls all objects from Stripe and
populates the local database with any records that don't already
exist there.

You might be wondering, "Why are they releasing this if there are only
a few things left?" Well, that thinking turned this into a two year
release... Trust me, this is a good thing.

Significant changes (mostly backwards-incompatible)
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

- **Idempotency**. #460 introduces idempotency keys and implements
idempotency for ``Customer.get_or_create()``. Idempotency will be
enabled for all calls that need it.
- **Improved Admin Interface**. This is almost complete. See #451 and
#452.
- **Drop non-trivial endpoint views**. We're dropping everything except
the webhook endpoint and the subscription cancel endpoint. See #428.
- **Drop support for sending receipts**. Stripe now handles this for
you. See #478.
- **Drop support for plans as settings**, including custom plan
hierarchy (if you want this, write something custom) and the dynamic
trial callback. We've decided to gut having plans as settings.
Stripe should be your source of truth; create your plans
there and sync them down manually. If you need to create plans
locally for testing, etc., simply use the ORM to create Plan models.
The sync rewrite will make this drop less annoying.
- **Orphan Customer Sync**. We will now sync Customer objects from
Stripe even if they aren't linked to local subscriber objects. You
can link up subscribers to those Customers manually.
- **Concurrent Live and Test Mode**. dj-stripe now supports test-mode
and live-mode Customer objects concurrently. As a result, the
User.customer One-to-One reverse-relationship is now the
User.djstripe_customers RelatedManager. (Thanks @jleclanche) #440. You'll
run into some dj-stripe check issues if you don't update your KEY settings
accordingly. Check our GitHub issue tracker for help on this.

SETTINGS
^^^^^^^^

- The ``PLAN_CHOICES``, ``PLAN_LIST``, and ``PAYMENT_PLANS`` objects
are removed. Use Plan.objects.all() instead.
- The ``plan_from_stripe_id`` function is removed. Use
Plan.objects.get(stripe\_id=)

SYNCING
^^^^^^^

- sync\_plans no longer takes an api\_key
- sync methods no longer take a ``cu`` parameter
- All sync methods are now private. We're in the process of building a
better syncing mechanism.

UTILITIES
^^^^^^^^^

- dj-stripe decorators now take a plan argument. If you're passing in a
custom test function to ``subscriber_passes_pay_test``, be sure to
account for this new argument.

MIXINS
^^^^^^

- The context provided by dj-stripe's mixins has changed.
``PaymentsContextMixin`` now provides ``STRIPE_PUBLIC_KEY`` and
``plans`` (changed to ``Plan.objects.all()``). ``SubscriptionMixin``
now provides ``customer`` and ``is_plans_plural``.
- We've removed the SubscriptionPaymentRequiredMixin. Use
``@method_decorator("dispatch",``\ `subscription\_payment\_required <https://github.com/kavdev/dj-stripe/blob/1.0.0/djstripe/decorators.py#L39>`__\ ``)``
instead.

MIDDLEWARE
^^^^^^^^^^

- dj-stripe middleware doesn't support multiple subscriptions.

SIGNALS
^^^^^^^

- Local custom signals are deprecated in favor of Stripe webhooks:
- ``cancelled`` -> WEBHOOK\_SIGNALS["customer.subscription.deleted"]
- ``card_changed`` -> WEBHOOK\_SIGNALS["customer.source.updated"]
- ``subscription_made`` ->
WEBHOOK\_SIGNALS["customer.subscription.created"]

WEBHOOK EVENTS
^^^^^^^^^^^^^^

- The Event Handlers designed by @wahuneke are the new way to handle
events that come through webhooks. Definitely take a look at
``event_handlers.py`` and ``webhooks.py``.

EXCEPTIONS
^^^^^^^^^^

- ``SubscriptionUpdateFailure`` and ``SubscriptionCancellationFailure``
exceptions are removed. There should no longer be a case where they
would have been useful. Catch native stripe errors in their place
instead.

MODELS
^^^^^^

.. rubric:: CHARGE
:name: charge

- ``Charge.charge_created`` -> ``Charge.stripe_timestamp``
- ``Charge.card_last_4`` and ``Charge.card_kind`` are removed. Use
``Charge.source.last4`` and ``Charge.source.brand`` (if the source is
a Card)
- ``Charge.invoice`` is no longer a foreign key to the Invoice model.
``Invoice`` now has a OneToOne relationship with ``Charge``.
(``Charge.invoice`` will still work, but will no longer be
represented in the database).

.. rubric:: CUSTOMER
:name: customer

- dj-stripe now supports test mode and live mode Customer objects
concurrently (See #440). As a result, the
``<subscriber_model>.customer`` OneToOne reverse relationship is no
longer a thing. You should now instead add a ``customer`` property to
your subscriber model that checks whether you're in live or test mode
(see djstripe.settings.STRIPE\_LIVE\_MODE as an example) and grabs
the customer from ``<subscriber_model>.djstripe_customers`` with a
simple ``livemode=`` filter.
- Customer no longer has a ``current_subscription`` property. We've
added a ``subscription`` property that should suit your needs.
- With the advent of multiple subscriptions, the behavior of
``Customer.subscribe()`` has changed. Before, ``calling subscribe()``
when a customer was already subscribed to a plan would switch the
customer to the new plan with an option to prorate. Now calling
``subscribe()`` simply subscribes that customer to a new plan in
addition to it's current subsription. Use ``Subscription.update()``
to change a subscription's plan instead.
- ``Customer.cancel_subscription()`` is removed. Use
``Subscription.cancel()`` instead.
- The ``Customer.update_plan_quantity()`` method is removed. Use
``Subscription.update()`` instead.
- ``CustomerManager`` is now ``SubscriptionManager`` and works on the
``Subscription`` model instead of the ``Customer`` model.
- ``Customer.has_valid_card()`` is now ``Customer.has_valid_source()``.
- ``Customer.update_card()`` now takes an id. If the id is not
supplied, the default source is updated.
- ``Customer.stripe_customer`` property is removed. Use
``Customer.api_retrieve()`` instead.
- The ``at_period_end`` parameter of ``Customer.cancel_subscription()``
now actually follows the
`DJSTRIPE\_PRORATION\_POLICY <http://dj-stripe.readthedocs.org/en/latest/settings.html#djstripe-proration-policy-false>`__
setting.
- ``Customer.card_fingerprint``, ``Customer.card_last_4``,
``Customer.card_kind``, ``Customer.card_exp_month``,
``Customer.card_exp_year`` are all removed. Check
``Customer.default_source`` (if it's a Card) or one of the sources in
``Customer.sources`` (again, if it's a Card) instead.
- The ``invoice_id`` parameter of ``Customer.add_invoice_item`` is now
named ``invoice`` and can be either an Invoice object or the
stripe\_id of an Invoice.

.. rubric:: EVENT
:name: event

- ``Event.kind`` -> ``Event.type``
- Removed ``Event.validated_message``. Just check if the event is valid
- no need to double check (we do that for you)

.. rubric:: TRANSFER
:name: transfer

- Removed ``Transfer.update_status()``
- Removed ``Transfer.event``
- ``TransferChargeFee`` is removed. It hasn't been used in a while due
to a broken API version. Use ``Transfer.fee_details`` instead.
- Any fields that were in ``Transfer.summary`` no longer exist and are
therefore deprecated (unused but not removed from the database).
Because of this, ``TransferManager`` now only aggregates
``total_sum``

.. rubric:: INVOICE
:name: invoice

- ``Invoice.attempts`` -> ``Invoice.attempt_count``
- InvoiceItems are no longer created when Invoices are synced. You must
now sync InvoiceItems directly.

.. rubric:: INVOICEITEM
:name: invoiceitem

- Removed ``InvoiceItem.line_type``

.. rubric:: PLAN
:name: plan

- Plan no longer has a ``stripe_plan`` property.
Use ``api_retrieve()`` instead.
- ``Plan.currency`` no longer uses choices. Use the
``get_supported_currency_choices()`` utility and create your own
custom choices list instead.
- Plan interval choices are now in ``Plan.INTERVAL_TYPE_CHOICES``

.. rubric:: SUBSCRIPTION
:name: subscription

- ``Subscription.is_period_current()`` now checks for a current trial
end if the current period has ended. This change means subscriptions
extended with ``Subscription.extend()`` will now be seen as valid.

MIGRATIONS
^^^^^^^^^^

We'll sync your current records with Stripe in a migration. It will take
a while, but it's the only way we can ensure data integrity. There were
some fields for which we needed to temporarily add placeholder defaults,
so just make sure you have a customer with ID 1 and a plan with ID 1 and
you shouldn't run into any issues (create dummy values for these if need
be and delete them after the migration).

BIG HUGE NOTE - DON'T OVERLOOK THIS
^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^^

Subscription and InvoiceItem migration is not possible because old records don't have Stripe IDs (so we can't sync them). Our approach is to delete all local subscription and invoiceitem objects and re-sync them from Stripe.
~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~~
We 100% recommend you create a backup of your database before performing this upgrade.
