<p><strong>FastAPI Users</strong> provides the necessary tools to work with SQL databases thanks to <a href="https://docs.sqlalchemy.org/en/13/core/">SQLAlchemy Core</a> and <a href="https://www.encode.io/databases/">encode/databases</a> package for full async support.</p>

<p>Notice that we pass it three things:</p>
<ul>
<li>A reference to your <a href="../../models/"><code>UserDB</code> model</a>.</li>
<li>A <code>database</code> instance, which allows us to do asynchronous request to the database.</li>
<li>The <code>users</code> variable, which is the actual SQLAlchemy table behind the table class.</li>
</ul>
<h2 id="what-about-sqlalchemy-orm">What about SQLAlchemy ORM?<a class="headerlink" href="#what-about-sqlalchemy-orm" title="Permanent link"></a></h2>
<p>The primary objective was to use pure async approach as much as possible. However, we understand that ORM is convenient and useful for many developers. If this feature becomes very demanded, we will add a database adapter for SQLAlchemy ORM.</p>
