Join is using alias column names

[thadclay]

var sql = require('sql');

var user = sql.define({
  name: 'user',
  columns: ['id', 'name', 'email', 'lastLogin']
});

var friendship = sql.define({
  name: 'friendship',
  columns: [
    { name: 'user_id', property: 'some_alias_here' },
    { name: 'friendId' }
  ]
});

var friends = user.as('friends');
var userToFriends = user
  .leftJoin(friendship).on(user.id.equals(friendship.some_alias_here))

console.log(userToFriends.toString());

The result of userToFriends is

"user" LEFT JOIN "friendship" ON ("user"."id" = "friendship"."user_id" AS "some_alias_here")

The proper result should be

"user" LEFT JOIN "friendship" ON ("user"."id" = "friendship"."user_id")
