There will luckily be no shopping cart on this site.

it shows this error "the method 'add' does not exist on"

Yeah, it can catch you out occasionally, for things like shopping carts. SHould be fine for simple many_many relations

CptPillow

seeing as its the ID that will be unique. I shouldnt need to touch those relations

That relationship is managed in a join table:

  1. ID | CustomerID | PropertyID
  2. ======================
  3. 1 | 1 | 2
