    <p>I want to create a generic class, whose builder would not return an instance of this generic class, but an instance of a dedicated child class.</p> <p>As Moose does automatic object building, I do not get to understand if this something possible, and how to create a Moose class with Moose syntax and having this behaviour.</p> <p>e.g.: The user asks: <code>$file = Repository-&gt;new(uri=&gt;'sftp://blabla')</code> .... and is returned an `Repository::_Sftp`` instance</p> <p>User would use <code>$file</code> as if it is a Repository instance, without the need to know the real subclass (polymorphism)</p> <p>Note:<br> As requested, maybe i should have been more clear about what i was trying to achieve:<br> The purpose of my class is to be able to add new Repository schemes (eg over sftp), by simply creating an "hidden" Repository::_Stfp class, and adding a case in the Repository constructor to factory the correct specialized object depending of url. Repository would be like a virtual base class, providing an interface that specialized objects would implement.<br> All of this is for adding new repository schemes without having the rest of the program to be modified: it would unknowingly deal with the specialized instance as if it is a Repository instance.</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.
