undefined method `reciters=' for #<Product:0xb71a77e8>

has_many :through doesn't have foos= before rails 2.1

Would you explain your answer a bit more? How come i can create a record without the error as i got when i was trying to update it? Any reference? Other solution to use instead?

Thanks,

Pretty much what I said. if you have has_many :customers you can do
customers= ..., but if you have has_many :customers, :through
=> :something_else, then until 2.1 you can't do it. It's just not
implemented (you'll have to do it yourself using the methods that are
available - the documentation on associations has a table of which
association types have which methods).

I tried with @product.reciter_ids = params[:reciters] before and i also got NoMethodError. Please help.

unless params[:reciters].blank?
@product.reciters = Qori.find(params[:reciters])

end

foo_ids= doesn't exist either. You need to use <<, delete etc... (or
upgrade to 2.1)
