I have the following:
class Invite < ActiveRecord::Base
belongs_to :user
has_many :invite_recipients
has_many :recipients, :through => :invite_recipients
end
class InviteRecipient < ActiveRecord::Base
belongs_to :invite
belongs_to :user_comm
validates_associated :user_comm, :invite
validates_uniqueness_of :user_comm_id, :scope => :invite_id
end
class UserComm < ActiveRecord::Base
end
I'd like to create a method for Invite with invite_text and a list of UserComms as the variables and then have it create a new invite with the following validations:
1. All UserComms are unique
2. The invite isn't saved unless all the associated InviteRecipients are saved as well
(in other words, the invite isn't valid unless all the created InviteRecipients are valid)
I'm not familiar with how to create model functions. Moreover, when I try something like this:
i = Invite.new(:invite_text => 'come join')
ir1 = InviteRecipient.new(:invite => i, :user_comm => user_comm1)
ir2 = InviteRecipient.new(:invite => i, :user_comm => user_comm2)
i.invite_recipients = [uc1, uc2]
i.save!
I get: SystemStackError: stack level too deep
