 The `modeladmin` module allows you to add any model in your project to the Wagtail admin. You can create customisable listing pages for a model, including plain Django models, and add navigation elements so that a model can be accessed directly from the Wagtail admin. Simply extend the `ModelAdmin` class, override a few attributes to suit your needs, register it with Wagtail using an easy one-line `modeladmin_register` method (you can copy and paste from the examples below), and you're good to go. Your model doesn’t need to extend `Page` or be registered as a `Snippet`, and it won’t interfere with any of the existing admin functionality that Wagtail provides.

 If you still rely on ModelAdmin, use the separate [wagtail-modeladmin](https://github.com/wagtail-nest/wagtail-modeladmin) package. The `wagtail.contrib.modeladmin` module will be removed in a future release.

 To provide a single, unified way to manage non-page Django models, the `modeladmin` contrib module has been deprecated in favor of the `snippets` module. This page explains how to migrate from `modeladmin` to `snippets`.
 
+```{versionadded} 5.2
+If you would rather not register the models as snippets, you can also use `ModelViewSet`. The migration explained with `SnippetViewSet` and `SnippetViewSetGroup` on this page can be substituted with `ModelViewSet` and `ModelViewSetGroup`. However, as of this release, the `ModelViewSet` does not support the following:
+
+- The use of `panels`, `edit_handler` as described in [](modeladmin_edit_handler_customisation).
+- The `get_queryset` method as described in [](modeladmin_get_queryset).
+
+See [](generic_views) for more details on using `ModelViewSet`.
