I am having a hard time to handle has_many associations.
  I have something like this

--in model farm

has_many :parties

--in farms_controller


where params[:farm][:parties] has values...

  In the cration of the farm it goes all well, but when updating it I
have problems...

1) It doesn't consider the parties validations
2) Even if it is all ok whith the detail, it is simply not saved.

thanks in advance
