Hi list
I have a question related to an has_many :through association.
Basicly I have a form that updates the entire has_many :through
collection AND the parent object.
from the form I have:
params[:parentobject] (all the attributes related to the parent object)
and
params[:childid]
an array of all the destination ID of the has many through association
How can I cleanly (and maybe atomicly since I’m using postgres)
destroy and create the needed records in the join table within the
update statement of the parent?
Thanks
Paolo
