Hello,

What's the best way to map a NxM relation that have some additional fields in the link table...

Table_User
ID
Username

Table_User_Right
ID_User
ID_Right
Type { 1 : Read, 2 : ReadWrite }


Table_Right
ID
Name

Thanks,
Catalin Andrei

You need an additional class for that and map it like that:

User m:1 UserRight 1:n Right
