Table cannot have association with itself?

In the associations documentation, it appears that a table can have an association with itself.

http://sequelizejs.com/docs/latest/associations#block-0-line-27.

 // Or let's define some self references
 var Person = sequelize.define('Person', { /* ... */})

 Person.hasOne(Person, {as: 'Father'})
 // this will add the attribute FatherId to Person

 // also possible:
 Person.hasOne(Person, {as: 'Father', foreignKey: 'DadId'})
 // this will add the attribute DadId to Person

 // In both cases you will be able to do:
 Person#setFather
 Person#getFather

I cannot seem to get this to work in Express. My code:

 module.exports = function(sequelize, DataTypes) {
   var Person = sequelize.define('Person', {
     name: DataTypes.STRING
   }, {
     classMethods: {
       associate: function (models) {
         Person.belongsTo(models.Family);
         Person.hasOne(Person, {as:'Parent', foreignKey: 'DadId'});
       }
     }
   });

   return Person;
 };

The Table gets created, but is missing the column for the parent (Dad) I expected to be there. Is this still supported, or am I doing something wrong? Thank you.

Disregard last, I figured out what you were asking for.

 -- Table: "Persons"

 -- DROP TABLE "Persons";

 CREATE TABLE "Persons"
 (
   id serial NOT NULL,
   name character varying(255),
   "createdAt" timestamp with time zone NOT NULL,
   "updatedAt" timestamp with time zone NOT NULL,
   "FamilyId" integer,
   "ParentId" integer,
   CONSTRAINT "Persons_pkey" PRIMARY KEY (id)
 )
 WITH (
   OIDS=FALSE
 );
 ALTER TABLE "Persons"
   OWNER TO postgres;

So clearly it was working. The database admin tool that I was using didn’t add the additional column until I exited the application and reopened it.

I apologize for the false positive on this, I’ll get a better db tool.

Alas, belongsTo and hasOne both have the same result.

 Person.hasOne(Person, {as: 'Parent'});

 Person.belongsTo(Person, {as: 'Parent'});

Thank you for you help and sorry once again.

I’m not sure how to see the table creation log.

Right now I’m using db.sequelize.sync({ force: true }).complete(function(err) {...});

and it doesn’t seen to dump to the console log. All the other calls do. Is there a way to enable this?
