Hi to all the crew,

I cannot figure out if is there a way to create/update an object and its  
associations with a single xml using a restful controller (put or post  
method)

Does anyone know how to handle this task (or tell me which is the best  
solution ?)…

For example:

Role (has many users through LinkUserRole)  
User (has many users through LinkUserRole)  
LinkUserRole (interface)

Now, I know very well how to hanldle the association of user/roles into  
controller for html input but how can I do when I receive an xml ?  
Which elements must be presente into the xml ?

Someone has an example ?

Many thanks in advance…
