Hello,
I have the following question regarding relationing 2 classes in xwiki. I made a class
Person with 2 properties (firstName, lastName) and a class Media with a prop. (title) and
then I made an object "Richard Gere" of class person and 2 objects "Pretty
Woman" and "Autumn at New York" of class Media. Now I would like to link
somehow the 3 objects, i.e to say that Richard Gere played in "Pretty Woman" and
also in the other movie (media). How can I do that? I don't seem to understand how to
link the already created objects one with another. For instance, I cannot create another
class with 2 properties, one of type Media and one of type Person, because these types
don't appear under "Type" on "Add Property" panel.
Please help me understand how can I do that in xwiki.
Ps. I heard something about attachments but I don't really understand how...
Thank you.

Not sure if it's the best solution but you could create a document
containing "Richard Gere" + "Pretty Woman" and "Autumn at New
York"
objects. This document would answer the question: "show me the films
with Richard Gere".

Indeed, or another possible option would be to add a property "playsIn"
of type "Database list" to the class "Person". The query associated
with
that property would be something like the one below, for fetching all
the Media titles:
======
select distinct prop.value from BaseObject as obj, StringProperty as
prop where obj.className='XWiki.Media' and prop.id.id = obj.id and
prop.id.name='title' order by prop.value
======
Or third possibility: simply use plain wiki links between the documents:
create three documents "Richard Gere", "Pretty Woman", "Autumn in
New
York", attach structured objects to each of them, then add a link to
"Pretty Woman" and "Autumn in New York" to the body of the document
"Richard Gere".
I hope this helps.
By the way, this type of question should rather be submitted to the
xwiki-users mailing-list! -> I propose we continue the discussion on
that list instead.
Cheers

Hi,
The property type you are looking for is Database List Class. It allows you
to create a list containing items of your choice.
So, what you need to do, is:
- Make a class called MediaHasActor, with two DBList properties, one called
Media, one called Person.
- The field called "Hibernate Query" should contain something like:
select
prop.value
from
BaseObject as obj,
StringProperty as prop
where
obj.className='XWiki.MediaClass' and (replace with '
XWiki.PersonClass' for the Person field
prop.id.id = obj.id and
prop.id.name='name' and
obj.name <> 'XWiki.MovieTemplate' (replace with '
XWiki.PersonTemplate' for the Person field
Now the relating object will display two list boxes, one with movies and the
other with actors. Of course, when you'll have thousands of movies and
actors, a select won't be the best option, so you will need to use an
AJAX-powered Suggest input.

Sergiu, this is great input, could you point me to something, which explains
how to use the AJAX Suggest Input with XWiki?
