# FastAPI 项目模板

## 修改配置文件
把根目录的`.env.example`文件复制为`.env`

## 虚拟环境
```bash
python -m venv ./venv
```

## 安装依赖
```bash
pip install -r requirements.txt --proxy=http://127.0.0.1:7890
```

## 数据迁移
```bash
alembic init alembic

alembic revision --autogenerate -m "Initial migration"

alembic upgrade head
```

## 运行
```bash
uvicorn main:app --reload
```

## 离线迁移
```
pip download -r requirements.txt -d wheelhouse
```

## 打包镜像
```bash
docker build -t fastapi-template .
docker run -p 9527:9527 fastapi-template
```

## 代码生成工具
```bash
set PYTHONPATH=%PYTHONPATH%;E:\fastapi-template
python generate\gen.py -m interface_info
```

## alembic 数据迁移
