您在代码中拼错了

ForeignKey

，

k

应该是大写

class Product(models.Model):
    category = models.ForeignKey(Category,related_name='products')
    name = models.CharField(max_length=200, db_index=True)
    slug = models.SlugField(max_length=200, db_index=True)
    image = models.ImageField(upload_to='products/%Y/%m/%d', blank=True)
    description = models.TextField(blank=True)
    price = models.DecimalField(max_digits=10, decimal_places=2)
    stock = models.PositiveIntegerField()
    available = models.BooleanField(default=True)
    created = models.DateTimeField(auto_now_add=True)
