 - **Apps**: Each Django app owns its models, views, API serializers, filtersets, forms, and tests.
-- **REST API**: DRF serializers live in `<app>/api/serializers.py`; viewsets in `<app>/api/views.py`; URLs auto-registered in `<app>/api/urls.py`.
+- **Views**: Use `register_model_view()` to register model views by action (e.g. "add", "list", etc.). List views typically don't need to add `select_related()` or `prefetch_related()` on their querysets: Prefetching is handled dynamically by the table class so that only relevant fields are prefetched.

 - Avoid adding new dependencies without strong justification.

-# Custom Model Actions
-
-Plugins can register custom permission actions for their models. These actions appear as checkboxes in the ObjectPermission form, making it easy for administrators to grant or restrict access to plugin-specific functionality without manually entering action names.
-
-For example, a plugin might define a "sync" action for a model that syncs data from an external source, or a "bypass" action that allows users to bypass certain restrictions.
-
-## Registering Model Actions
-
-To register custom actions for a model, call `register_model_actions()` in your plugin's `ready()` method:
-
-```python
-# __init__.py
-from netbox.plugins import PluginConfig
-
-class MyPluginConfig(PluginConfig):
-    name = 'my_plugin'
-    # ...
-
-    def ready(self):
-        super().ready()
-        from utilities.permissions import ModelAction, register_model_actions
-        from .models import MyModel
-
-        register_model_actions(MyModel, [
-            ModelAction('sync', help_text='Synchronize data from external source'),
-            ModelAction('export', help_text='Export data to external system'),
-        ])
-
-config = MyPluginConfig
-```
-
-Once registered, these actions will appear grouped under your model's name when creating or editing an ObjectPermission that includes your model as an object type.
