Have a look at the Rails Guide on debugging. 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.
