I have models for User and Message. Users should be able to send messages with
multiple Users as the recipients. Here are the associations:
User:
has_many :received_messages, :class => "Message", :through =>
:message_recipients, :accessible => true
has_many :message_recipients, :dependent => :destroy, :accessible => true,
:foreign_key => 'recipient_id'
has_many :sent_messages, :class => "Message", :foreign_key => 'sender_id',
:accessible => true
Message:
belongs_to :sender, :class => "User", :creator => true, :foreign_key =>
'sender_id'
has_many :recipients, :class => "User", :through => :message_recipients,
:accessible => true
has_many :message_recipients, :dependent => :destroy, :accessible => true
MessageRecipient: (join model)
belongs_to :message
belongs_to :recipient, :class => "User", :foreign_key => 'recipient_id'
I set this up, then ran hobo g migration (hobo 1.3 pre31) here is the beginning
of the trace:

/Users/mark/Documents/Hobo/class_management/app/models/message.rb:10
line 10 in message.rb is the belongs_to line.
Any ideas where I'm going wrong?
