fastapi_amis_admin 是一个功能强大的框架旨在帮助开发者在使用 FastAPI 进行 web 开发时能够快速创建一个高效且易于管理的后台界面。通过结合 FastAPI 和 amis 的优势fastapi_amis_admin 提供了一种简洁而高效的方式来构建和管理 web 应用程序的后台。
主要特性 高性能基于 FastAPI保证了高并发和快速响应的能力。 高效率通过 amis 实现快速构建可视化界面减少开发时间。 易于使用基于标准的 Python 类型提示简化开发流程。 开源免费遵循 Apache2.0 协议鼓励社区参与和贡献。 具体用法
安装 首先确保你的 Python 版本是 3.6 或更高。然后使用 pip 进行安装
bash pip install fastapi_amis_admin 2. 创建 FastAPI 应用 如果你还没有一个 FastAPI 项目可以先创建一个
python from fastapi import FastAPI app FastAPI() 3. 定义你的数据模型 例如如果你有一个用户模型
python from pydantic import BaseModel class User(BaseModel): id: int name: str email: str 4. 使用 fastapi_amis_admin 快速生成管理后台 python from fastapi_amis_admin import AdminSite, ModelAdmin from your_models import User # 引入你刚定义的数据模型
admin_site AdminSite(app) # 创建一个 AdminSite 实例
注册你的数据模型到 AdminSite 中
admin_site.register(ModelAdmin(User)) 5. 启动你的 FastAPI 应用 使用 UVicorn 或其他你喜欢的 ASGI 服务器来运行你的应用。例如使用 UVicorn
bash uvicorn main:app --reload # ‘main’ 是你的主模块名‘app’ 是你的 FastAPI 实例名 6. 访问管理后台 默认情况下后台管理界面会在 /admin 路径下生成。你可以在浏览器中访问 http://localhost:8000/admin 来查看和使用管理后台。使用你定义的模型名称例如“User”作为菜单项来管理相应的数据。
