Whether somebody with no account may see something was being answered one feature at a time: a securesend_allow_guests setting, an enable flag per kiosk, and very nearly a third for guides - each with its own settings page, its own vocabulary and its own hand-written branch inside a route. Every one of them answered a permissions question, and this app already administers permissions per role. So a caller with no token is not nobody: they hold the seeded `guest` role. require_permission consults it when there is no identity, which is the entire mechanism. The role is seeded holding NOTHING, so an upgrade opens no door; a site opens one by ticking a box in the same grid it uses for every other role, and closes it the same way. Revocation is read on every request rather than cached, because taking guest access away is what somebody does the moment they realise what they opened, and it has to bite immediately. The redundant @jwt_required() above require_permission is gone from 184 routes. It was belt-and-braces before; now it is actively wrong, because it refuses a request with no token before the permission check can have an opinion, so a grant would appear to do nothing. What a guest may hold is bounded. Any .view or .read permission is grantable. A WRITE has to be blessed by whoever owns it, through the new get_guest_grantable_permissions hook (contract 0.21.0), and Secure Send is the only case that exists: sending a password to a vendor is the one write this product means to offer somebody who never signs in. Everything else is refused by the API and greyed out in the grid rather than warned about - a checkbox that quietly makes deleting an asset anonymous is not a warning anybody reads twice. A guest write records no creator: the trail says when and from where, never who, and that is the reason for the bar. GE-Enforce and Slides gained read permissions so they can be opened to guests without handing out the manage right. Their read routes accept either through require_any_permission, so nothing an existing manager could reach has moved. The navigation endpoint now returns only what the caller can actually reach. Without that a signed-out visitor gets a sidebar of the whole app where every link bounces off the login page, which reads as a broken site rather than as a closed door. A nav item may name several permissions; holding any one is enough, which is what GE-Enforce and Slides need now that a viewer and a manager hold different strings. Two things this found on the way: current_user is a LocalProxy, so `current_user is None` is False for a request with nobody behind it - harmless under a required JWT, an AttributeError the moment verification became optional. And an image pasted into a guide before its first save was never attached to it, so it was visible to editors and invisible to every reader; saving now attaches it, and `flask guides fix-images` repairs what is stored. The guides guest setting written earlier today is gone. Granting guides.view to the guest role replaces it, which is the point.
USB plugin - CMMC USB check-in/out database contract
The USB plugin tracks removable-media check-in/out for CMMC compliance. Device
and log state live in a separate, read-write MySQL database (cmmc_usb),
reached with parameterized pymysql via cmmc_usb_connection(). Names of people
are resolved from the HR employee directory (see the employees plugin).
The plugin's own reference tables (usbdevicetypes, usbdevices,
usbcheckouts) live in the main app database; only the live check-in/out data
is in cmmc_usb.
The schema is standardized across sites - the
cmmc_usbcheck-in/out solution is the same deployment everywhere, so the tables below match as-is and no schema adaptation is needed. The database name may differ per site, though - setcmmc_usb_db_name(defaultcmmc_usb) to match the local name. The view recipe at the end is only a fallback for a site that somehow differs. (Contrast the employee directory, which genuinely varies per site.)
Connection
Credentials resolve settings-first, then environment, except the password which is env-only (never stored in the app database).
| Field | Setting key (editable in the setup wizard) | Env var (fallback) |
|---|---|---|
| Host | cmmc_usb_db_host |
CMMC_USB_DB_HOST |
| Database | cmmc_usb_db_name |
CMMC_USB_DB_NAME |
| User | cmmc_usb_db_user |
CMMC_USB_DB_USER |
| Password | (not stored) | CMMC_USB_DB_PASSWORD |
Set the password in .env; the setup wizard's Features step shows the exact
line to paste. This database is read-write - the app account needs
SELECT, INSERT, UPDATE. Engine is MySQL/MariaDB (pymysql).
Required schema
The plugin runs raw SQL against these tables (or views - see below).
devices
| Column | Type | Notes |
|---|---|---|
device_id |
VARCHAR | Primary key; the device serial/tag |
device_desc |
VARCHAR | Description |
device_owner |
VARCHAR | Owner |
status |
VARCHAR | Check-in/out state |
locker_location |
VARCHAR | Where the device is stored |
Operations: SELECT (list + by id), INSERT (register device), UPDATE
(edit fields, change status).
checkinoutlog
| Column | Type | Notes |
|---|---|---|
log_id |
INT (PK) | Auto id |
badge_number |
VARCHAR | Person's badge |
device_id |
VARCHAR | FK to devices.device_id |
action |
VARCHAR | check-in / check-out |
timestamp |
DATETIME | When it happened |
scanned_viruses |
(text/int) | Scan result |
locker_location |
VARCHAR | Locker at time of event |
sanitized |
(bool/int) | Sanitization flag |
Operations: SELECT (history per device), INSERT (log an event).
users
| Column | Type | Notes |
|---|---|---|
badge_number |
VARCHAR | Primary key; the scanned badge |
first_name |
VARCHAR | Given name |
last_name |
VARCHAR | Surname |
Operations: SELECT by badge, INSERT (auto-add a badge on first scan).
Employee directory dependency
To turn a scanned badge into a name, the plugin also reads the HR employees
directory (via the employees plugin's connection). A badge shaped 0<digits>BZ
carries a PayNo (the digits); lookups try employees.SSO and employees.PayNo.
See plugins/employees/README.md for that schema and connection.
Adapting a different site schema (recommended: views)
Sites whose USB-tracking database uses different table/column names should
create read-only/updatable views named devices, checkinoutlog, and
users that map local columns to the names above. Example:
CREATE VIEW devices AS
SELECT
asset_tag AS device_id,
description AS device_desc,
owner AS device_owner,
state AS status,
storage_bay AS locker_location
FROM usb_assets;
Because the plugin writes to devices/checkinoutlog/users, either make the
views updatable (single-table views usually are) or expose real tables with
these column names. Grant the app account SELECT, INSERT, UPDATE.
Notes:
device_idandbadge_numberare the natural keys the plugin matches on.- If
cmmc_usbis unreachable, USB endpoints return an error and the rest of the app keeps working (the feature degrades, it does not crash the app).
