djangoldp-stripe 0.1.10

djangoldp package for working with Stripe payments

djangoldp-stripe

A DjangoLDP package supporting Stripe payments. Uses dependency dj-stripe to achieve much of the functionality, a library for handling Stripe payments in Django

Requirements

• djangoldp 2.1

• Python 3.6.5

• Requires the installation of a DjangoLDP server

• You will need to set up a Stripe client

Installation

• You will need to set the following settings to your settings.yml:

dependencies:
   # ...
   - djangoldp-stripe

ldp_packages:
   # ...
   - djangoldp_stripe

server:
   # ...
   STRIPE_LIVE_MODE: True  # Should be False when testing, True in production
   DJSTRIPE_USE_NATIVE_JSONFIELD: True  # if using SQLite, set this to False
   DJSTRIPE_FOREIGN_KEY_TO_FIELD: "id"

• Set STRIPE_LIVE_SECRET_KEY and STRIPE_TEST_SECRET_KEY in your OS environment variables where the server is run. These settings will then be securely imported when you next configure. Alternatively, you can add them to the settings.yml:

server:
    # ...
    STRIPE_LIVE_SECRET_KEY: ""
    STRIPE_TEST_SECRET_KEY: ""

You can find these settings via the Stripe dashboard

• Optionally you can change the setting LDP_STRIPE_URL_PATH to change the path where Django Stripe's urls will be accessible. By default it is "stripe/", i.e. http://localhost:8080/stripe/. These urls are provided by DjStripe and implement all of the necessary webhooks to keep your Stripe data sync'ed with your Django data

• In the Stripe dashboard, register a webhook listening to all events (or just those you want to keep up-to-date) and point them to your API url + your webhook endpoint. So if your API was hosted on https://yoursite.com/ and you didn't change the LDP_STRIPE_URL_PATH, then the endpoint would be https://yoursite.com/stripe/webhooks/

• In the created webhooks, find your webhook secret, and set this in the OS variable (or server setting) DJSTRIPE_WEBHOOK_SECRET. It is a string which will start whsec_

• Optionally add djangoldp_stripe.middleware.StripeSubscriptionRequiredMiddleware to your MIDDLEWARE settings in settings.yml. When this middleware is included then it will restrict access to certain requests so that they are only accessible by users with an active subscription. Add a list of all paths which should be restricted to the setting INCLUDE_FROM_GLOBAL_STRIPE_SUBSCRIPTION_REQ

server:
   # ...
   MIDDLEWARE:
     - "djangoldp_stripe.middleware.StripeSubscriptionRequiredMiddleware"
   INCLUDE_FROM_GLOBAL_STRIPE_SUBSCRIPTION_REQ:
     - '/my-custom-path/'

Note that this middleware does not check that an anonymous user is subscribed. To prevent this being a problem, make sure that your server does not give anonymous users permissions that they shouldn't have, so that they must login before accessing the application

• Optionally add the setting REDIRECT_URL_NO_SUBSCRIPTION if you plan to use UserHasValidSubscriptionView and wish to modify its' behaviour, e.g. http://localhost:8000/checkout-session/?lookup_key=test-subscription

• Run djangoldp install

• Run djangoldp configure

• Run python manage.py djstripe_sync_models. Anytime you run this command your database will be manually synchronised with your Stripe records. If for example your site went down for a time, you should re-run this command

## Migrating existing customers

After configuration, you can do this by running:

djangoldp configure
python manage.py djstripe_init_customers
python manage.py djstripe_sync_plans_from_stripe

StripeSubscriptionPermissions

This package can be used to provide custom permissions on your models and views. To do this you can use the permissions class StripeSubscriptionPermissions or the utility functions in permissions.py

• Set up the required product permissions on your model:

class MyModel(Model):
    # ...

    class Meta(Model.Meta):
       # ...
       PERMS_REQUIRED_STRIPE_SUBSCRIPTIONS = ['prod_xxxx',]

When applying either the permission class to a LDPViewSet or the utility function, you can now control access based on the products a requesting user is subscribed to
