We already calculate the correct `billed_licenses` early in the
function, so just used that to fix the bug where a legacy server
scheduled for upgrade doesn't respect the manual license count
set by the user.
I missed a some places to check on last pass:
* For automanaged licenses when the license updates.
* When plan is changed.
* When migrating existing customers to legacy plan.
I accidentally free trials for both cloud and self hosted
enabled while testing, hence didn't catch it.
This mostly involves fixing `is_free_trial_offer_enabled` to
return the correct value and providing it the correct input.
We simply apply discount to both the plans.
Since the discount is saved in `customer.default_discount` it
will applied now to any future plans as well, even if customer
downgrades and the upgrades again.
For the last form (with Full Name and ToS consent field), this pretty
shamelessly re-uses and directly renders the
corporate/remote_realm_billing_finalize_login_confirmation.html
template. That's probably good in terms of re-use, but calls for a
clean-up commit that will generalize the name of this template and the
classes/ids in the HTML.
When a remote server uploads statistics, we update the
LicenseLedger using the audit logs uploaded.
We iterate over the RemoteRealmAuditlog data for the concerned
realm starting from the event_time of the last LicenseLedger
created for that customer and update the ledger based on each event.
If the RemoteRealmAuditLog has stale data, it means the server
stopped or never uploaded data. We raise MissingDataError in such
cases when a user action led to calculating licenses count from
stale data.
We add a 'get_remote_realm_guest_and_non_guest_count'
function that queries 'RemoteRealmAuditLog' to get
the guest and non_guest count for that remote_realm.
This function is used in 'RemoteRealmBillingSession'
to calculate the current count of billed licenses.
* For free trial, don't show number of licenses for current billing period.
* For free trial scheduled to downgrade, don't show number of
licenses for next billing period.
Adds a helper since there are only a few different parameters for
all BillingSession child clases, `build_support_url`.
Also, renames `get_support_url` to more explicitly note that it
is for realms: `get_realm_support_url`.
Use of `string_id` in the sponsorship request email content was
removed in commit d3834f8b9, but it is still used in the email
subject.
Updates the email subject to use the billing_entity_display_name,
which is still the Realm.string_id for Zulip Cloud organizations.
Sets this string as "billing_entity" in the context and subject
template.
This commit moves the 'update_license_ledger_if_needed' and its
helper function 'update_license_ledger_for_automanaged_plan'
to the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
