fastapi-admin实现


    <h1 style="color: black; text-align: left; margin-bottom: 10px;"><span style="color: black;">1、</span>集思广益</h1>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">FastAPI操作数据库的<span style="color: black;">文案</span>,网上有<span style="color: black;">非常多</span>。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">FastAPI因其原生支持异步,且支持Pydantic标准格式校验,广泛受到<span style="color: black;">研发</span>者的<span style="color: black;">喜爱</span>。</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">那样</span><span style="color: black;">怎样</span>支持异步数据库?并继续支持Pydantic呢?</span></p>
    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;"><span style="color: black;">那样</span>FastAPI能<span style="color: black;">不可</span>像Django那样支持 </span><strong style="color: blue;"><span style="color: black;">admin</span></strong><span style="color: black;">后台呢?<span style="color: black;">能够</span>快捷的对数据库表进行CRUD呢?</span></p>

    <p style="font-size: 16px; color: black; line-height: 40px; text-align: left; margin-bottom: 15px;"><span style="color: black;">SQLModel 是一个库,用于<span style="color: black;">经过</span> Python 代码和 Python 对象与SQL 数据库进行交互。它被设计为直观、易于<span style="color: black;">运用</span>、高度兼容和强大。</span></p>
