Python return int（value）ValueError:以10为基数的int（）的文本无效：“Umi Falafel”

我已从数据库导出csv文件，并希望将csv信息存储在django模型中。我收到了ValueError问题

我已尝试在.py文件中将字符串转换为整数

加载供应商数据.py

models.py

堆栈跟踪

---

我希望在django db中导入csv文件时不会出现错误。在实例化模型时，应该始终使用关键字参数，而不是位置参数

vendors = Vendors(name=row[0], location=row[1], price_range=row[2])

---

我仍然收到一个错误：return Database.Cursor.executeself，query，params django.db.utils.IntegrityError:数据类型不匹配

class Vendors(models.Model):
   name = models.CharField(max_length=100)
   location = models.CharField(max_length=100)
   price_range = models.CharField(max_length=100)

   def __str__(self):
      return self.name


class Act(models.Model):
   Name = models.CharField(max_length=100)
   Stage = models.CharField(max_length=100)
   Start_Time = models.TimeField()
   End_Time = models.TimeField()
   Date = models.DateField()
