fastapi:alembic找不到models目录下的数据表model

两个要注意的环节：

一：alembic/env.py

要有这一行把models下的类引入：

from app.models import *

如下：

from app.db.dbbase import MyBaseModel
from app.models import *  # noqa: F401,F403
# this is the Alembic Config object, which provides
# access to the values within the .ini file in use.
config = context.config

# Interpret the config file for Python logging.
# This line sets up loggers basically.
if config.config_file_name is not None:
    fileConfig(config.config_file_name)

# add your model's MetaData object here
# for 'autogenerate' support
# from myapp import mymodel
# target_metadata = mymodel.Base.metadata
# target_metadata = None
target_metadata = MyBaseModel.metadata

二：models/__init__.py

要把models目录下的类都包含进来

# app/models/__init__.py
from app.models.app_user import AppUser

__all__ = ["AppUser"]
