Hello,

I have a normal has\_many :through setup that i need to setup with checkboxes and looking for the best approach.

user has\_many :entries has\_many :contests, :through =\> :entries

contest

has\_many :entries

entry belongs\_to contest belongs\_to user

entry - ID, USER\_ID, CONTEST\_ID, RANDOM\_NUMBER

how would i setup a checkbox/radio button so that i can easily submit to the entry model for each user\_id/contest\_id/random\_number value ?

Thanks Adam
