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.
Moves the 'update_license_ledger_for_manual_plan' function
to the 'BillingSession' abstract class.
This refactoring will help in minimizing duplicate code while
supporting both realm and remote_server customers.
This cannot be so short if we're adding an intermittent "check your
details, agree to ToS and confirm login" page. We're also considering
having users potentially share these links.
These names were picked when I still thought these endpoints would serve
both the RemoteRealm and RemoteZulipServer based flows. Now that it's
known these are RemoteRealm-only endpoints, the _server in the names no
longer makes sense.
Also adds `SWITCH_PLAN_TIER_AT_PLAN_END` for `CustomerPlan`
which will be used to mark status of remote server legacy
plans which are scheduled for an upgrade.
The logic for BillingSession.is_sponsored_or_pending would be the
same for all three child classes of BillingSession, so this should
be a method on the BillingSession abstract class.
Creates a process_support_view_request method for BillingSession
to process the various support requests that relate to the billing
system.
Moves approve_realm_sponsorship, update_realm_sponsorship_status,
and attach_discount_to_realm to this new BillingSession method.
Adds a new abstract property to BillingSession to have a string
value, billing_entity_display_name, to use for support messages
sent when these requests are processed.
The "send_invoice" and "charge_automatically" strings used by stripe
for the `collection_method` are referred to both as the "billing
method" and "billing modality" in the billing code.
Because we send this as data to stripe as either `collection_method`
or `billing_modality`, renames any references that are any form of
"billing method".
Analogical to the more complex mechanism implemented for the RemoteRealm
flow in a previous commit in
authenticated_remote_realm_management_endpoint.
As explained in the code comment, this is much easier because:
In this flow, we can only redirect to our local "legacy server flow
login" page. That means that we can do it universally whether the user
has an expired
identity_dict, or just lacks any form of authentication info at all -
there are no security concerns since this is just a local redirect.
Analogical to 1df8e00d7c which implemented
this for the RemoteRealm auth flow.
Except here we don't need to add next_page to the IdentityDict
(LegacyServerIdentityDict in this flow), because the redirect happens
immediately at remote_billing_legacy_server_login upon login - so no
need to have a structure to carry the info through intermediate steps.
Implements a nice redirect flow to give a good UX for users attempting
to access a remote billing page with an expired RemoteRealm session e.g.
/realm/some-uuid/sponsorship - perhaps through their browser
history or just their session expired while they were doing things in
this billing system.
The logic has a few pieces:
1. get_remote_realm_from_session, if the user doesn't have a
identity_dict will raise RemoteBillingAuthenticationError.
2. If the user has an identity_dict, but it's expired, then
get_identity_dict_from_session inside of get_remote_realm_from_session
will raise RemoteBillingIdentityExpiredError.
3. The decorator authenticated_remote_realm_management_endpoint
catches that exception and uses some general logic, described in more
detail in the comments in the code, to figure out the right URL to
redirect them to. Something like:
https://theirserver.example.com/self-hosted-billing/?next_page=...
where the next_page param is determined based on parsing request.path
to see what kind of endpoint they're trying to access.
4. The remote_server_billing_entry endpoint is tweaked to also send
its uri scheme to the bouncer, so that the bouncer can know whether
to do the redirect on http or https.
This default setup will be more realistic, matching the ordinary
conditions for a modern server.
Especially needed as we add bouncer code that will expect to have
RemoteRealm entries for realm_uuid values for which it receives
requests.
