Body
I did it with a behavior, by adapting to INameFromTitle in behaviors.py <pre><code>class INameFromBrandAndModel(Interface): """ Interface to adapt to INameFromTitle """ class NameFromBrandAndModel(object): """ Adapter to INameFromTitle """ implements(INameFromTitle) adapts(INameFromBrandAndModel) def __init__(self, context): pass def __new__(cls, context): brand = context.brand model = context.modeltype title = u'%s %s' % (brand,model) inst = super(NameFromBrandAndModel, cls).__new__(cls) inst.title = title context.setTitle(title) return inst </code></pre> in behaviors.zcml or configure.zcml <pre><code><plone:behavior title="Name from brand and model" description="generates a name from brand and model attributes" for="plone.dexterity.interfaces.IDexterityContent" provides=".behavios.INameFromBrandAndModel" /> <adapter factory=".behaviors.NameFromBrandAndModel" /> </code></pre> Then disable INameFromTitle behavior in <code>profiles/types/your.contenttype.xml</code>. Voila. This integrates very well and shows a proper title in the default view and navigation. Removing <code>context.setTitle(title)</code> from the adapter would just leave us with a proper id, but no title set. This does not change the title autocratically after editing. I had, so far, no success with overriding the <code>klass</code> property of my content types, as often suggested. If you define the <code>title</code> attribute in your schema, like: <pre><code>class IBike(form.Schema): """A bike """ title = schema.TextLine( title = _(u'Title'), required = False, ) </code></pre> you can easily change the title later. Hiding the title field in the addForm should be done, to avoid misunderstandings.

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.
