Hi,
I'm newcomer to SS, and I have seen a lot of doc, and have made working the tutorial about Students and Project.

I'm trying to achieve a very similar stuff than the tutorial one.
I have a CarManufacturer class
a CarManufacturerHolders which aims to contain all CarManufacturers
and a TypeCar class which aims to describe the kind of car (Audi has a A1 car type, but also A3 , .....)

meanwhile I add attributes to my CarManufacturer class, a name and a specific code....
And when I have a look on the DashBoard (Admin panel), when I try to add a CarManufacturer I do not have those attributes.
I have only the ones concerning a "page", i.e. Name Url Segment ...

I don't understand whether I do a mistake or whether I forgot something. I would expect having those fields in the admin Panel when I create this kind of Objects.

My example is a very trivial one, very similar to the tutorial one except that in the tutorial the Project class (extends Page) doesn't have $db specific attributes

Hope Am I clear enough...

thanks in advance for your hints.

Thanks IOTI,

I solved my problem, it was a bad relationship described.
A newcomer classic error....

Thanks
