Examples¶
While the Configuration documentation contains all available options in detail, this page shows them in conjunction to provide different examples on how to display pydantic models and settings.
Default configuration¶
This example shows the default out-of-the-box configuration of autodoc_pydantic. In contrast, it also shows how standard sphinx autodoc displays the same example code.

Complete configuration¶
This example represents a rendered output for which all features are enabled. It deviates from the default configuration above because it contains redundant information which is most likely not required. However, for demonstration purposes, this scenario covers all available display options for pydantic models/settings.
