Wakanda Page Prototype Custom Save
<p>I have 3 tables, <code>sale</code>, <code>detail_sale</code>, and <code>item</code> like this:</p>

<pre><code>sale {id, date}

detail_sale {id, sale, item, qty}

item {id, name}
</code></pre>

<p>So, in wakanda how do I insert table <code>sale</code> and <code>detail_sale</code> in one page with page prototype?</p>

<p>That I read in <a href="http://livedoc.wakanda.org/Datasource/Server-Datasources/save.301-607761.en.html" rel="nofollow">Wakanda Documentation</a>, I insert <code>sale</code> table fist and then insert <code>detail_sale</code>. Can I insert <code>sale</code> and <code>detail_sale</code> in one time?</p>
