python - 匹配的查询不存在 django heroku

Question

我已经将我的应用程序部署到heroku ..

但是当我尝试转到该页面时，我从日志中收到此错误：

apps.adminview.models.Templates.DoesNotExist: Templates matching query does not exist.

这是来自我的 adminview 模型，您可以看到它是正确创建的：

...
class Templates(models.Model):
    description     = models.TextField(null=True, blank=True)
    template_name   = models.TextField(null=True, blank=True)
    isSelected      = models.BooleanField(default=False)
    temp_selected   = models.BooleanField(default=False)
    width_field      = models.IntegerField(default=0, null=True)
    height_field     = models.IntegerField(default=0, null=True)
    image_path      = models.ImageField(
                                        width_field="width_field", 
                                        height_field="height_field"
                                    )
    def __str__(self):
        return "("+str(self.id)+") " + self.template_name

任何人都可以帮助我吗？谢谢！。

顺便说一句，如果您需要，这是来自我的 settings.py ：
