dj-stripe 2.1.1

Django + Stripe Made Easy

dj-stripe

Stripe Models for Django.

Introduction

dj-stripe implements all of the Stripe models, for Django. Set up your webhook and start receiving model updates. You will then have a copy of all the Stripe models available in Django models, no API traffic required!

The full documentation is available here: https://dj-stripe.readthedocs.io/

Features

• Subscriptions
• Individual charges
• Stripe Sources
• Stripe v2 and v3 support
• Supports SCA regulations, Checkout Sessions, and Payment Intents
• Tested with Stripe API 2019-09-09 (see https://dj-stripe.readthedocs.io/en/latest/api_versions.html )

Requirements

• Django >= 2.1
• Python >= 3.5
• Supports Stripe exclusively. For PayPal, see dj-paypal instead.
• PostgreSQL engine (recommended): >= 9.4
• MySQL engine: MariaDB >= 10.2 or MySQL >= 5.7

Quickstart

Install dj-stripe:

pip install dj-stripe

Add djstripe to your INSTALLED_APPS:

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

Tell Stripe about the webhook (Stripe webhook docs can be found here) using the full URL of your endpoint from the urls.py step above (e.g. https://example.com/stripe/webhook).

Add your Stripe keys and set the operating mode:

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 = False  # Change to True in production
DJSTRIPE_WEBHOOK_SECRET = "whsec_xxx"  # Get it from the section in the Stripe dashboard where you added the webhook endpoint

Add some payment plans via the Stripe.com dashboard.

Add to urls.py:

path("stripe/", include("djstripe.urls", namespace="djstripe")),

Run the commands:

python manage.py migrate

python manage.py djstripe_init_customers

python manage.py djstripe_sync_plans_from_stripe

Running the Tests

Assuming the tests are run against PostgreSQL:

createdb djstripe
pip install tox
tox

Follows Best Practices

This project follows best practices as espoused in Two Scoops of Django: Best Practices for Django 1.11.

History

2.1.1 (2019-10-01)

This is a bugfix-only version:

• Updated webhook signals list (#1000).
• Fixed issue syncing PaymentIntent with destination charge (#960).
• Fixed Customer.subscription & .valid_subscriptions() to ignore status=incomplete_expired (#1006).
• Fixed error on paymentmethod.detached event with card_xxx payment methods (#967).
• Added PaymentMethod.detach() (#943).
• Updated help_text on all currency fields to make it clear if they’re holding integer cents (StripeQuantumCurrencyAmountField) or decimal dollar (or euro, pound etc) (StripeDecimalCurrencyAmountField) (#999)
• Documented our preferred Django model field types (#986)

Upcoming migration of currency fields (storage as cents instead of dollars)

Please be aware that we’re looking at standardising our currency storage fields as integer quanta (cents) instead of Decimal (dollar) values, to match stripe.

This is intended to be part of the 3.0 release, since it will involve some breaking changes. See #955 for details and discussion.

Squashed dev migrations

As per our migration policy unreleased migrations on the master branch (migration numbers >=0004) have been squashed.

If you have been using the 2.1.0dev branch from master, you’ll need to run the squashed migrations migrations before upgrading to >=2.1.0.

The simplest way to do this is to pip install dj-stripe==2.1.0rc0 and migrate, alternatively check out the 2.1.0rc0 git tag.

2.0.5 (2019-09-12)

This is a bugfix-only version:

• Avoid stripe==2.36.0 due to regression (#991)

2.0.4 (2019-09-09)

This is a bugfix-only version:

• Fixed irreversible migration (#909)

2.0.3 (2019-06-11)

This is a bugfix-only version:

• In _get_or_create_from_stripe_object, wrap create _create_from_stripe_object in transaction, fixes TransactionManagementError on race condition in webhook processing (#877/#903).

2.0.2 (2019-06-09)

This is a bugfix-only version:

• Don’t save event objects if the webhook processing fails (#832).

• Fixed OperationalError seen in migration 0003 on postgres (#850).
• Fixed issue with migration 0003 not being unapplied correctly (#882).
• Fixup missing SubscriptionItem.quantity on Plans with usage_type="metered" (#865).
• Fixed Plan.create() (#870).

2.0.0 (2019-03-01)

• The Python stripe library minimum version is now 2.3.0.
• PaymentMethod has been renamed to DjstripePaymentMethod (#841). An alias remains but will be removed in the next version.
• Dropped support for Django < 2.0, Python < 3.4.
• Dropped previously-deprecated stripe_objects module.
• Dropped previously-deprecated stripe_timestamp field.
• Dropped previously-deprecated Charge.receipt_number field.
• Dropped previously-deprecated StripeSource alias for Card
• Dropped previously-deprecated SubscriptionView, CancelSubscriptionView and CancelSubscriptionForm.
• Removed the default value from DJSTRIPE_SUBSCRIPTION_REDIRECT.
• All stripe_id fields have been renamed id.
• Charge.source_type has been deprecated. Use Charge.source.type.
• Charge.source_stripe_id has been deprecated. Use Charge.source.id.

• Fixed IntegrityError when REMOTE_ADDR is missing (#640).
• New models: - ApplicationFee - ApplicationFeeRefund - BalanceTransaction - CountrySpec - ScheduledQuery - SubscriptionItem - TransferReversal - UsageRecord
• The fee and fee_details attributes of both the Charge and Transfer objects are no longer stored in the database. Instead, they access their respective new balance_transaction foreign key. Note that fee_details has been deprecated on both models.
• The fraudulent attribute on Charge is now a property that checks the fraud_details field.
• Object key validity is now always enforced (#503).
• Customer.sources no longer refers to a Card queryset, but to a Source queryset. In order to correctly transition, you should change all your references to customer.sources to customer.legacy_cards instead. The legacy_cards attribute already exists in 1.2.0.
• Customer.sources_v3 is now named Customer.sources.
• A new property Customer.payment_methods is now available, which allows you to iterate over all of a customer’s payment methods (sources then cards).
• Card.customer is now nullable and cards are no longer deleted when their corresponding customer is deleted (#654).
• Webhook signature verification is now available and is preferred. Set the DJSTRIPE_WEBHOOK_SECRET setting to your secret to start using it.
• StripeObject has been renamed StripeModel. An alias remains but will be removed in the next version.
• The metadata key used in the Customer object can now be configured by changing the DJSTRIPE_SUBSCRIBER_CUSTOMER_KEY setting. Setting this to None or an empty string now also disables the behaviour altogether.
• Text-type fields in dj-stripe will no longer ever be None. Instead, any falsy text field will return an empty string.
• Switched test runner to pytest-django
• StripeModel.sync_from_stripe_data() will now automatically retrieve related objects and populate foreign keys (#681)

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.

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 2.0.0.

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 2.0.0.

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 (renamed to DjstripePaymentMethod in 2.0). 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 2.0.0. 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 2.0.0

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 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) 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

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).

  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 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.

  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)

  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

  INVOICE

• Invoice.attempts -> Invoice.attempt_count

• InvoiceItems are no longer created when Invoices are synced. You must now sync InvoiceItems directly.

  INVOICEITEM

• Removed InvoiceItem.line_type

  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

  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

Warning

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.
