Ruby on Rails

does each hall have to be specifically designated as hallx?
and do halls exist independently of spectacle?

Assuming that halls exist independently, it sounds like having a join
table and position attributes on the join should work
spectacle
has_many :halls

spectacle_hall_join
belongs_to :hall
belongs_to :spectacle

hall
has_many :spectacles, through: spectacle_hall_join

should do the trick

if you really need to have the ability to call hallx you could add a
scope to the join
scope :position, lambda {|x| where position: x} # assumes code
calls only, if users can supply a value you will want to prevent XSS on this

you can take this further to get exactly what you need.

Hope this helps.
