I am beyond flummoxed with this one. I've been through a number of questions and answers pertaining to this code, made several adjustments, and I'm still getting 4 errors on 5 tests. Please help. Thanks!

from django.db import models

class Song(models.Model):
    title = models.CharField(max_length=255),
    artist = models.CharField(max_length=255),
    performer = models.ForeignKey("Performer"),
    length = models.IntegerField(default=0),

    def __str__(self):
        return '{} by {}'.format(self.title, self.artist)

class Performer(models.Model):
    name = models.CharField(max_length=255)

    def __str__(self):
        return self.name
