  • State changed from “new” to “resolved”

  When you're doing m:m with a custom name you need to specify the intermediary model and relationships explicitly, eg:

  http://gist.github.com/230179

  If you follow the DM defaults, and just use "has n, :mailers, :through => Resource" inside Person, the explicit intermediary model can be removed, and the relationship in Mailer can become "has n, :people, :through => Resource" too.

  Thanks Dan,

  So, using what you said above, I can created custom relationship and a default relationship at the same time: as seen http://gist.github.com/230255.

  Thanks to you and dbussink for all the help!

  Okay, so the stranger part of the problem re-appeared.

  If I create two people:

  Person.create(:name => "Austin")
  Person.create(:name => "John")
  Person.create(:name => "John")

  Mailer.create(:person => Person.first, :people => Person.all(:name => John))
  Mailer.create(:person => Person.first, :people => Person.all(:name => John))

  Mailer.first().person # Austin
  Mailer.get(2).person # John, What!??!

  Is this because of the overlap of person and people? How can I fix it?
