This commit moves the main context creation part of the
'billing_home` view to a new shared
'BillingSession.get_billing_page_context' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
Moves the 'make_end_of_cycle_updates_if_needed' function to
the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Since the function is called from our main daily billing cron job
as well, we have changed 'RealmBillingSession' to accept 'user=None'
(our convention for automated system jobs).
There is a discrepancy between price per license shown on billing
and upgrade page for annual billing frequency due to difference
in methods used to calculate the amount.
To fix it, we use the same method on both the pages.
I didn't use the helpers.format_money directly here since that would
create a visual delay in showing the price per license which will
not be nice considering that will be the only thing on this page
being updated that way.
The stripe fixture used is same as
free_trial_upgrade_by_card--Customer.retrieve.3.json
This commit moves a major portion of the 'upgrade`
view to a new shared 'BillingSession.do_upgrade' method.
This refactoring will help in minimizing duplicate code
while supporting both realm and remote_server customers.
Moves the 'process_initial_upgrade' function to the
'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Updates `process_initial_upgrade` to take a plan_tier parameter,
so that information can be specific to the type of BillingSession.
Note that ideally the plan tier would be passed as metadata to the
stripe.checkout.Session, but in order to do so, we need to be able
to update the generated stripe fixtures for tests. So for now, we
set the plan tier directly in the stripe event handler code.
Instead of hard coding the string for the stripe.InvoiceItem and
stripe.Invoice statement_descriptor, we use the name of the plan
that was just created.
Creates `do_change_plan_type` as a BillingSession abstract method
as an alias for updating the plan_type for a realm (and eventually
remote server).
This removes the last direct reference to a customer's realm in
`process_initial_upgrade`.
Creates `current_count_for_billed_licenses` as an abstract method
in BillingSession class, to get the latest seat count for the realm
(and eventually remote server) connected to the customer.
Moves the 'setup_upgrade_checkout_session_and_payment_intent'
function to the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
Generated with both parellel=1 and generate-stripe-fixtures params
on test-backend locally.
Note that the previous series of commits need these test fixtures
to pass CI. If those are changed, then this commit should be updated
or dropped and replaced with a commit that updates the fixtures
based on the new changes.
Instead of using the data from the stripe.SetupIntent for processing
an initial upgrade for the free trial session types, use the metadata
from the stripe.checkout.Session that was returned.
The metadata is the same for both the checkout session and the setup
intent.
Updates generate stripe fixtures to use test credit card strings from
Stripe, instead of creating fake stripe.PaymentMethods for the tests
with the test credit card numbers provided by Stripe.
According to stripe's documentation for attaching payment methods to
customers (see https://stripe.com/docs/api/payment_methods/attach),
payment methods should be attached to customers through a SetupIntent
or PaymentIntent, which is what we do as we process new customers
and accounts.
Updates create_stripe_customer so that it is clear that the payment
method should not be added when we directly create a new stripe
customer.
There is a 22 char limit on the stripe.Invoice.statement_descriptor
field. The current value for that field in this error case, "Zulip
Cloud Standard Credit" is 27 chars.
Updates the value for this error case to be "Cloud Standard Credit".
This calculates the largest amount of messages sent within a month for
the last 3 months. The query is targeted for the specific use-case in
this function - for finding the count for a specific server. For
calculating this in bulk for a large number of remote server an
adapted, bulk query will be needed - rather than running this one in a
loop, which would likely be very inefficient.
Instead of randomly generating an integer for the realm string_id
and realm name use a counter to increment the string ids by one.
This way if a particular realm fails the test, it will be easier
to identify which one failed.
Also, removes unused Customer objects that were being returned on
realm creation in the test, as these were not being checked/used
in the test.
In commit a3093fad9, we made Hamlet a billing admin for testing.
Because the approve sponsorship flow sends messages from the
notification bot to both organization owners and billing admins,
we need to update that test to cover both of those user types.
Adds `create_stripe_payment_intent` to the BillingSession abstract
class for the initial upgrade process, which is used only in
`setup_upgrade_checkout_session_and_payment_intent`.
Adds a helper dataclass for the data used to create the stripe
payment intent, StripePaymentIntentData, for the implementation of
more than one child class of BillingSession.
Also adds two abstract helper functions for getting the above stripe
payment intent data as well as updating that data for a stripe
checkout session that is associated with a payment intent:
update_data_for_checkout_session_and_payment_intent,
get_data_for_stripe_payment_intent.
Adds `create_stripe_checkout_session` to BillingSession abstract
class, which is then used in all places where a stripe.checkout.Session
and Session were created: start_retry_payment_intent_session,
start_card_update_stripe_session, and
setup_upgrade_checkout_session_and_payment_intent.
Adds a `billing_session_url` abstract property to the BillingSession
abstract class and for the RealmBillingSession child class sets that
value to `self.realm.uri`.
setup_upgrade_checkout_session_and_payment_intent was not using the
datetime values that were being returned by compute_plan_parameters,
so just get the price per license directly.
Moves `update_billing_method_of_current_plan` to the BillingSession
abstract class.
Adds a helper function for support views for the realm case:
`update_realm_billing_method`.
Moves `update_sponsorship_status` to BillingSession abstract class
as `update_customer_sponsorship_status`.
Updates the support views to have a helper for updating this on a
realm: `update_realm_sponsorship_status`.
Makes `approve_sponshorship` an abstract method in BillingSession
abstract base class and moves the implementation for realms to the
RealmBillingSession child class.
Adds `approve_realm_sponsorship` helper function that's used in
the support view and initiates the billing session.
Creates an enum class, AuditLogEventType, and an abstract method in
BillingSession, get_audit_log_event, so that we have an abstraction
for getting the audit log event type since it might be different for
Customer objects with a realm vs a remote_server.
This moves the logic for `attach_realm_discount`, which is used in
the support view, to be in the BillingSession class.
Updates the function name to be `attach_discount_to_customer` so
that the context is generalized vs realm specific.
Updates RealmBillingSession implementation to account for actions
that are initiated by a support admin user.
Also moves the helper function `get_discount_for_realm` that is
only used in support views to `corporate/lib/support.py`.
So that all child classes of BillingSession generate the same data
structure for customers that are created in Stripe, revise
`get_data_for_stripe_customer` to return a specific dataclass:
StripeCustomerData.
So that `update_or_create_stripe_customer` can work for Customer
objects with either a realm or remote_server, we create an abstract
base class, BillingSession, and implement a child class for the
current implementation of Customer objects with a realm.
Refactoring `update_or_create_stripe_customer` also moves
`create_stripe_customer` and `replace_payment_method` to the
BillingSession class.
In ensure_customer_does_not_have_active_plan, we were already going
through the Customer table to get/check for an active CustomerPlan.
Now we directly get/check for an active CustomerPlan with via the
Customer, which allows for reusing this function for Customer
objects without a Realm set.
