Invitations between the two models Rails

Question

I have two models. Weddings and guests.

class Wedding
  has_many guests
end

class Guest
  has_many weddings
end

How do I make what guests can accept or decline the invitation?

Answer 1

You need to do a many to many relation with an intermediate model. See guides. See 2.4 The has_many :through Association topic here.

On that new model/table you can add an attribute (a boolean "decline" attribute maybe) to control guests assistance...
