Ok I do understand now the Problem with the Symbols.
But with @product.continent = Continent.find({:id => continent_id.to_i})
I get
undefined local variable or method `continent_id'
waht I do understand because I'm in def update and the parameters witch
are passed are:
Parameters: {"commit"=>"Upd.... ,
"product"=>{"image_url"=>"/images/Burger.png",
"expirience_points"=>"10", "price"=>"1.99", "title"=>"WHOPPER®",
"description"=>"....", "continent_id"=>"7"}, "id"=>"1",
"controller"=>"products"}
But how do I get now from :product the "continent_id"=>"7"
