I have set up a class which:
# deals with 2 models : A and B, A has_many B, and B has_one A
# extends ModelAdmin

When I do a dev/buil, all things look good.
I have a gridfield for A, a Tab for B.
When I go in Pane B (page under Tab B) and when I click on "Add B" for adding a new object, then I have the good attributes of my B model

BUT beacuse of the has_one relationship that B has with A I get a DropDonwList in which SilverStripe gathers the A existing model with their ID displayed.
I would like to get the names of the A instances instead of the Id but I'm unaware how to achieve this.

One can't add a B object related to a A already existing object by selecting its Id number. Would be great to select the name of the A instance.

Do someone know how to achieve this ?

Add the drop down field manually and map the DataObject. Take alook at the DropdownField documentation for an example.

Thanks to reply and help me.

I solved the problem by doing the way you described.
We have to map the Id of the records to the Name

And everything works great.

The deeper I go into SS, the more I think it is a great framework. Well Designed.

Nice day
