我刚刚在Item模型中添加了新的imageField。然后运行命令makemigrations，在执行迁移命令后，我开始获取“ sqlite3.OperationalError：无此类列：REFERRED.id”。然后，我删除了更改并尝试迁移，但仍然存在相同的错误。我之前尝试过所有相同的讨论，但没有任何变化。仍然有相同的错误。因此，由于此错误，我无法添加任何字段
class Item(models.Model):
title = models.CharField(max_length=100)
price = models.FloatField()
discount_price = models.FloatField(blank=True, null=True)
category = models.CharField(choices=CATEGORY_CHOICES, max_length = 2)
label = models.CharField(choices=LABEL_CHOICES, max_length = 1)
slug = models.SlugField()
description = models.TextField()
def __str__(self):
return self.title
def get_absolute_url(self):
return reverse('core:''product', kwargs={
'slug': self.slug
})
def get_add_to_cart_url(self):
return reverse('core:''add-to-cart', kwargs={
'slug': self.slug
})
def get_remove_from_cart_url(self):
return reverse('core:''remove-from-cart', kwargs={
'slug': self.slug
})
这是回溯：
