    <p>The project I am working on uses Plone's awesome Dexterity plugin. A couple of my custom content types have very specific names that must be computed. The way I had originally accomplished this before was by adding <em>plone.app.content.interfaces.INameFromTitle</em> as a behavior in the object's generic setup entry, per the manual's directions:</p> <pre><code>&lt;?xml version="1.0"?&gt; &lt;object name="avrc.aeh.cycle" meta_type="Dexterity FTI"&gt; ... &lt;property name="schema"&gt;myproject.mytype.IMyType&lt;/property&gt; &lt;property name="klass"&gt;plone.dexterity.content.Item&lt;/property&gt; ... &lt;property name="behaviors"&gt; &lt;element value="plone.app.content.interfaces.INameFromTitle" /&gt; &lt;/property&gt; ... &lt;/object&gt; </code></pre> <p>Then I created an adapter that would provide INameFromTitle:</p> <pre><code>from five import grok from zope.interface import Interface import zope.schema from plone.app.content.interfaces import INameFromTitle class IMyType(Interface): foo = zope.schema.TextLine( title=u'Foo' ) class NameForMyType(grok.Adapter): grok.context(IMyType) grok.provides(INameFromTitle) @property def title(self): return u'Custom Title %s' % self.context.foo </code></pre> <p>This method is very similar to that suggested in this blog post:</p> <p><a href="http://davidjb.com/blog/2010/04/plone-and-dexterity-working-with-computed-fields">http://davidjb.com/blog/2010/04/plone-and-dexterity-working-with-computed-fields</a></p> <p>Unfortunately, this method stopped working after plone.app.dexterity beta and now my content items don't have their names assigned properly.</p> <p>Would anyone happen to know how to extend Dexterity's INameFromTitle behavior for very specific naming use-cases?</p> <p>Your help is much appreciated, thanks!</p>

A row detail

Detail views are divided into sections. All the information in the data section comes from columns in the selected row. The other sections display data from other, related rows.

Related data can be related in a to-one or a to-many fashion. Captions of data related in a to-many fashion link to a list view showing a filtered view of the table.

Try moving around until you find a non-empty to-many entry and click on the label to get to one. You can move back to the root by clicking on the database name in the header.
