This visualization shows the relationship between Django model fields and their cached property aliases in a database schema. It uses the Django ORM’s `models.DateTimeField` and `models.ForeignKey` to define the base order row’s timestamp and two related inventory item references, while `@cached_property` methods expose either the confirmed stock item or the unconfirmed item model. The code demonstrates how `is_confirmed` switches between the two foreign keys, returning `None` for the unused one. The example relies on Django’s model inheritance and the `cached_property` decorator to manage lazy-loaded relationships, illustrating a pattern where alternate field names are hidden behind a single logical accessor.

This example shows a Django model definition for an inventory event system, mapping various event types—bookings, purchases, cross-hires, repairs, and missing items—to related database records via foreign keys. The code uses Django’s `models.ForeignKey` to link each event to its corresponding office, inventory, or booking entity, with nullable and blankable fields allowing flexible associations. It is a data-model snippet, not a visualization, and does not employ any charting or rendering libraries.

This example shows a PostgreSQL query plan for a Django ORM query that retrieves inventory events by filtering on stock items associated with a specific item model. The visualization renders the EXPLAIN output as a tree of hash joins and sequential scans, using the `explain` command to expose query execution details. The code includes Python Django model definitions and raw SQL, with the query plan revealing how the database optimizes multiple LEFT OUTER JOINs and subqueries against inventory, booking, purchase, and cross-hire tables.

This example visualizes a Django data model’s query-set filtering logic as a directed graph, showing how `ItemModelQuerySet` methods such as `consumable`, `tracked`, and `hireable` branch from the base `ItemModelManager`. The graph nodes represent query-set operations and their type-based filter relationships, with edges indicating method chaining. It uses the `PassThroughManager` API to expose custom queryset methods, while the rendering approach likely relies on a JavaScript library like `d3.forceSimulation` for node layout, though the code itself focuses on the Python-side model definitions. The data source is the hardcoded queryset class structure from the gist.

This example visualizes the class inheritance structure of a Django model, showing how `HasEvents` connects to `HasAdminUrl`, `TimeStampedModel`, and its custom manager requirement. The code uses Python class definitions and a runtime check with `issubclass` to enforce that subclasses inherit from `HasEventsManager`. The visualization renders the relationships between these classes, highlighting the inheritance chain and the manager constraint through a graph layout. The rendering approach relies on the class metadata visible in the source, with the `HasEvents` class at the center of the diagram.

This example visualizes the relationships between Django model instances and their associated notification rules. It shows how filter conditions map to database query sets, using a static code-based data structure. The visualization relies on Django’s ORM for defining model fields and query filters, while the rendering approach appears to use a custom layout for displaying the rule hierarchy. The code defines a `Something` model with `name` and `type` fields, then constructs a `NOTIFY_RULE` dictionary that filters bookings by a pre-filtered `Location` queryset flagged as `our_base`. No interactive or animated elements are present.

This example demonstrates a code snippet that creates a stock order in a Django-based inventory system. It shows the sequence of operations: instantiating a `PurchaseOrder` with a given supplier, adding a row with the specified quantity, and attaching a hidden arrival event for the creation date and location. The code relies on Django’s object-relational model (`PurchaseOrder.objects.create` and related row creation) to persist the order. It also uses a custom method (`add_hidden_arrival`) to link the order to a location, illustrating how business logic can be embedded in model methods rather than external visualization tools. The rendering approach is not visual; it is a server-side data-handling example.

A Django model method updates inventory records by deleting any stock counts with a timestamp at or after a given time, then inserting a new count for that item. The `set_stock_count` function filters `StockCount.objects` using `timestamp__gte`, removes matching entries, and creates a fresh record with the supplied stock level. This demonstrates a time-series upsert pattern for tracking product availability over time, though the code shows no visualization logic, only the data-management layer.

This example visualizes the relationships between Django model fields, notifier types, and their associated timing rules for invoice reminders. It shows how `Invoice` objects map to different notifier actions (sending invoices, sending reminders 7 days or 1 day before due) through a structured configuration. The code defines an `Invoice` model with `Choices` for notifier types and a `NOTIFIER_EVENTS` dictionary that pairs each reminder type with date-field criteria, time-delta ranges, and status filters. The visualization likely renders this Django model logic as an interactive graph, using Python’s model definitions and timedelta calculations to display the branching decision paths.
