Hy @vi4m :
icon = 'user' name = 'user_additional_info' label = _('Additional info') url_name = 'user_additional_info'
It is working if I assign the user directly on the BackOfficeAsset . If I do it from My model with the "Mitarbeiter" Field, it won't Show up in additional Info.
I am Pretty sure it has something to do with the Api, or the View of RalphUser or the my Model by itself ? There is something that I am missing...A class method Maybe ? My Model is Pretty Basic...
So if the User Field from the BackofficeAsset gets populated by my "Mitarbeiter" Field Value, then the Additional_USer_Info.html, will also get populated.
