好吧，让django来为你处理应用程序和模型：

from pathlib import Path

from django.apps import apps
from django.conf import settings

project_root = Path(settings.BASE_DIR)

# Loop through all apps
for app_name, app_conf in sorted(apps.app_configs.items()):

    # Local app within project_root?
    try:
        Path(app_conf.path).relative_to(project_root)
    except ValueError:
        # Not a local app => skip
        continue

    # Loop through all models of app_name
    for model_name, model_cls in sorted(apps.all_models[app_name].items()):
        print(f'App: {app_name:<25s} Model: {model_name}')

        # Now work with the model ..
        #  .. create documentation
        #  .. export documentation

这应该给予你一个开始你的任务。
