Thanks for all these comments!
However somethings else maybe going on... it's failing and I don't know
why.
Even with this code.
class WelcomeController < ApplicationController
def index
unless params[:location][:id].blank?
# location is set
@teachers = Teacher.all
@locations = Location.all
else
# no location set
@teachers = Teacher.all
@locations = Location.all
end
end
end
it fails with

The error occurred while evaluating nil.[]
