Foreign Key definitions on Sequelize Models

I'm trying to create Sequelize (3.20) models of these 2 tables on Postgresql:

| user  |          | comment  |
|-------|          |----------|
| id    |          | id       |
| email |          | userId   |

user table is on crm schema and comment table is on comment schema. comment.userId has foreign key to user.id.

var User = db_conn.define('user', {
  email: {
    ...
  }
}, {
  ...
});
User.sync({force: true}).then(function () {
  return User.create({
    email: '[email protected]'
  });
});

var Comment = db_conn.define('comment', {
  userId: {
    type: Sequelize.INTEGER,
    allowNull: false,
    references: {
        model: User,
        key  : 'id',
        deferrable: Sequelize.Deferrable.INITIALLY_DEFERRED
    }
  }
}, {
  ...
});
Comment.sync({force: true}).then(function () {
  return Comment.create({
    userId: 1,
  });
});

But i'm getting this error:

Unhandled rejection SequelizeDatabaseError: relation "user" does not exist

Generated SQL :

CREATE TABLE IF NOT EXISTS "comment"."comment" ("id"   SERIAL, "userID" INTEGER NOT NULL REFERENCES "user" ("id") DEFERRABLE INITIALLY DEFERRED);

As you see it's creating a FK to user table not 'crm'.'user' table. And it's cauisng error because there is no user table on public schema. Can you please tell me what is I'm missing?

Thank you.
