Could anyone explain me how works the categories and how can I use? I
read the ' Rapid Application Development with ERP5' but I still don't
understand how I can use that.

I'm trying to create a reference from classe A to class B (for
example). What do I need to do?

Waiting for answers... : )

Just state in the portal_types that portal_type A is based category
"foocat". (supposing that foocat is an existing base category in
portal_categories)

You will then get an accessor created for you
getFoocatValue()
setFoocatValue()

You can set a relation between object a and object b by stating
a.setFoocatValue(b)

Then retrieve the relation by
a.getFoocatValue()

JPS.

Thanks Jean, another question....

Do categories support multiple references? Example:

One class A has references to many (n or *) classes B. Is it possible?

Yes, you have by the same time theses generators generated :

getFoocatValueList()
b.setFoocatValueList([b,c])

You can search for the keyword "accessor" on erp5.org, there is a document
describing rad (Rapid Application Developpment). It is a bit outdated but
very interesting, I may update it on wiki.erp5.org one day when I will
get some free time.

Seb.
