This prep commit adds logic to calculate discount based
on flat_discount and flat_discounted_months. Creates
a stripe invoice item for the discount.
This will be used by remote realm/server billing system
while invoicing via cron job.
Earlier, in process_initial_upgrade, the flat_discount value
wasn't converted into dollars when specified in the invoice
description, resulting in showing the incorrect value of $2000
as a discount.
This commit converts the value in cents to dollars and adds tests
to verify the invoice generated.
Updates the HTML input field to have a min of 0, max of 99.99 and
allow increments of 0.01.
Also, use format_discount_percentage for displaying the customer
default discount in the support form.
For self hosted basic plan, we need to allow customers to subscribe
without purchasing 10 licenses and also we need to allow customer
take fully use the available discount so that if the add more
users in the future, the full discount was already applied.
To fix above, we set minimum user count to the least number
of licenses we require for the charge to be positive after applying
the complete discount.
We return expected_end_timestamp as "None" for the plans to be
downgraded if number of users is not more than MAX_USERS_WITHOUT_PLAN
since they will be downgraded to self-managed plan and would
have push notifications enabled.
Adds a support action for updating the minimum licenses on a
customer object once a default discount has also been set.
In the case that the current billing entity has a current active
plan or a scheduled upgrade to a new plan, then the minimum
licenses will not be updated.
Previously, the message string was sent as a success response to
the context, which could have been confusing or ignored when shown
in the support admin view.
- Make `self.write_to_audit_log` support a `background_update:
bool=False` parameter that can be passed when code that might have an
acting user happens to trigger a background update.
- Make `make_end_of_cycle_updates_if_needed` pass that parameter for its
direct audit log writes.
- Audit code that `make_end_of_cycle_updates_if_needed` calls and make
sure those write audit logs this way too.
- Pass the user in the `billing_page` code that had to avoid it as a
workaround:
```
# BUG: This should pass the acting_user; this is just working
# around that make_end_of_cycle_updates_if_needed doesn't do audit
# logging not using the session user properly.
billing_session = RealmBillingSession(user=None, realm=user.realm)
```
This moves the function which computes can_push and
expected_end_timestamp outside RemoteRealmBillingSession
because we might use this function for RemoteZulipServer
as well and also renames it.
The call to 'get_billable_licenses_for_customer' during the
'sync_license_ledger_if_needed' step should use the audit_log's
event_time while calculating 'current_count_for_billed_licenses'.
Earlier, it used timezone_now(), resulting in the latest user count
recorded corresponding to each audit log.
This is a general link for logging into the billing system on behalf of
a server, but it's tied to the .contact_email and takes the user
straight to the /deactivate/ page via the next_page mechanism.
This prep commit makes 'sync_license_ledger_if_needed'
function a 'BillingSession' abstract method.
We'll override the method for RemoteServerBillingSession
in the next commit.
This prep commit extracts out the code block that determines the
last license ledger for the customer plan having automanage_licenses
set to True into a new BillingSession method named
'get_last_ledger_for_automanaged_plan_if_exists'.
We'll be using this function while implementing the
'sync_license_ledger_if_needed' method for RemoteServerBillingSession.
