A tricky problem involved named through associations in Geddy's Model. This current arrangement throws the error `Error: The property "adminTeamTeamId" is not a valid property on the TeamAdmin model.`

Team.js

var Team = function () {
  
  this.hasMany('TeamUsers');
	this.hasMany('Users', {through: 'TeamUsers'});

	this.hasMany('TeamAdmins');
	this.hasMany('Admins', {
		through: 'TeamAdmins',
		model: 'Users'
	});
	
}

exports.Team = Team;

TeamAdmin.js

var TeamAdmin = function () {

	this.belongsTo('AdminTeam',{model:'Team'});
	this.belongsTo('User');

};

exports.TeamAdmin = TeamAdmin;

TeamUser.js

var TeamUser = function () {

	this.belongsTo('Team');
	this.belongsTo('User');

};

exports.TeamUser = TeamUser;

User.js

var User = function () {
  
  this.hasMany('TeamUsers');
  this.hasMany('Teams', {through: 'TeamUsers'});

  this.hasMany('TeamAdmins');
  this.hasMany('AdminTeams', {through: 'TeamAdmins', model:'Teams'});

}

exports.User = User;
