create_models.py

The markata.plugins.create_models plugin dynamically creates Markata's core Pydantic models by combining model fragments from various plugins. This enables extensible and type-safe data models.

Installation

This plugin is built-in and enabled by default through the 'default' plugin. If you want to be explicit, you can add it to your list of plugins:








        

hooks = [
    "markata.plugins.create_models",
]

Uninstallation

Since this plugin is included in the default plugin set, to disable it you must explicitly add it to the disabled_hooks list if you are using the 'default' plugin:








        

disabled_hooks = [
    "markata.plugins.create_models",
]

Note: Disabling this plugin will break most of Markata's functionality as it's responsible for creating core models.

Configuration

No explicit configuration is required. The plugin automatically creates models from registered model fragments.
