我要做一个纯后端的API接口项目，学生信息管理，用的是FastAPI框架，使用的模块有sqlalchemy+pydantic+schemas+logging，请帮我列出合理的目录结构及代码文件，并给出每个文件详细的代码编写
：
目录结构：
- src
- app
- models.py # 定义数据库模型
- schemas.py # 定义学生信息数据结构
- views.py # 定义API接口

README.md：项目介绍文件，包括简介、技术框架、环境搭建、项目运行及测试等信息。
.env：环境变量文件，用于存放数据库连接等信息。
requirements.txt：项目所需依赖包文件，用于记录项目所需要的第三方依赖包。
config.py：配置文件，用于存放项目相关的配置信息，如数据库链接、logging配置等。
app.py：主文件，用于创建FastAPI的实例，绑定路由、数据库以及日志等。
models/init.py：models初始化文件，用于记录模块内容。
models/model.py：模型文件，用于创建数据库模型，使用pydantic和sqlalchemy。
services/init.py：services初始化文件，用于记录模块内容。
services/service.py：服务文件，用于处理业务逻辑，调用model文件中的数据库模型进行数据库操作。
routes/init.py：routes初始化文件，用于记录模块内容。
routes/route.py：路由文件，用于定义API接口，调用services文件中的service进行处理。

hi
ervan is dat de schoonheid van je huid gedurende de dag toeneemt. In de ochtend heb je een frisse en stralende huid. In de avond ben je klaar om de nacht in te gaan met een gezonde en glanzende huid. De ingrediënten in deze crème helpen ook bij het verminderen van fijne lijntjes en rimpels, het verbeteren van de algemene teint en het verminderen van oneffenheden zoals acne en littekens. De crème is ook vrij van parabenen, sulfaten, phthalaten en kunstmatige kleur- en geurstoffen. Het is een goede keuze voor mensen met een gevoelige huid.
