Then set breakpoint in the view code just before the error and inspect the data to see if it all looks right. First though I would check the docs for collection_select and check that nil is valid as the first parameter. Note particularly in http://ap.rubyonrails.org/classes/ActionView/Helpers/FormOptionsHelper.html#M000455 the second sentence and what it says about the object parameter. I suspect you have another problem with one of the other params that is causing the map problem. Perhaps one of them is nil also.
