hi!

i’m trying to build some stuff with RoR again and now got a little  
problem and i hope someone can help me.

i’ve got the models securities, events ans allocations. there are  
many\_to\_many relations between securities,events and allocations with i  
made according to the rails recipes book (securities and events are  
connected through the allocations with contains some extra data). now i  
want to have a link in the events-listing that will redirect me to the  
allocations-new where i’ll just select the security and fill in the  
extra data. now i can’t fidure out how to pass the event\_id to the form  
and get error since the event\_id must be set.

also it would be cool if i could set several allocations for one event  
at the same time.

please help! - thanks
