Question

创建了一个名为Email的新模型，但是使用makemigrations和migrate我没有检测到任何更改。在runserver上，我收到以下错误：

ProgrammingError at /admin/uploader/email/
relation "uploader_email" does not exist
LINE 1: SELECT COUNT(*) AS "__count" FROM "uploader_email"

我已尝试过stackoverflow的所有建议，我有：

已删除的迁移文件
运行migrate --fake和--fake-initial
迁移上传者（专门调用该应用）

没有任何工作，数据库根本不会被修改。

有什么想法吗？

型号：

class Email(models.Model):
    ROUNDS_LIST = (
        ('1', '1'), ('2', '2'), ('3', '3'), ('4', '4'), ('5', '5'), ('6', '6'), ('7', '7'), ('8', '8'), ('9', '9'), ('10', '10'),
    )
    project = models.ForeignKey(Project)
    client = models.ForeignKey(Client, null=True, blank=True)
    name = models.CharField(max_length=256, null=True, blank=True)
    filename = models.CharField(max_length=256, null=True, blank=True)
    width = models.CharField(max_length=3, null=True, blank=True)
    height = models.CharField(max_length=3, null=True, blank=True)
    review_round = models.CharField(max_length=3, choices=ROUNDS_LIST, default=1)
    zip_file_upload = models.FileField(blank=True, null=True, upload_to=get_upload_file_name)

    def save(self, *args, **kwargs):
        self.slug = slugify(self.name)
        filename, file_extension = os.path.splitext(self.zip_file_upload.name)
        self.name = filename
        self.filename = filename + ".html"

        super(Email, self).save(*args, **kwargs)

    class Meta:
        verbose_name_plural = "HTML Emails"

    def __unicode__(self):
        return self.name
