<div dir="ltr"><div><div><div>z3c.relationfield is the closest thing I've used to a foreign key.

<br></div>They rely heavily on the Zope Component Architecture. So, in order to get the most out of zc.relation you need to grasp really well the idea behind the ZCA (see <a href="http://www.muthukadan.net/docs/zca.html">http://www.muthukadan.net/docs/zca.html</a>).<br>

<blockquote class="gmail_quote" style="margin:0 0 0 .8ex;border-left:1px #ccc solid;padding-left:1ex">Hi all,<br>
<br>
Reading this tutorial (<a href="http://grok.zope.org/documentation/how-to/using-a-relationfield-for-relationships-between" target="_blank">http://grok.zope.org/<u></u>documentation/how-to/using-a-<u></u>relationfield-for-<u></u>relationships-between</a>), the author uses `z3c.relationfield'. I was wondering what other libraries exist to do this?<br>
<br>
I should probably ask this on ZODB lists but I thought here I may find some hints about which approach suits Grok better.<br>
<br>
TIA,<span class="HOEnZb"><font color="#888888"><br>
