從腳本填充數據庫時Django Heroku DataError

我製作了一個讀取xml文件並從中填充數據庫的腳本。當我在本地運行它時，它沒有問題。但是，當我在Heroku上運行它，它會通過，並填充一些數據（剛好6個對象），但隨後引發此錯誤：從腳本填充數據庫時Django Heroku DataError

skripta_vnos.py是我填充劇本我在外殼

DataError: value too long for type character varying(100)

我的模式看起來運行像這樣：

class Supply(models.Model): 
    name = models.CharField(max_length=255) 
    maticna = models.CharField(max_length=255) 
    organ = models.CharField(max_length=255, null=True, blank=True) 
    pos = models.CharField(max_length=255, null=True, blank=True) 
    city = models.CharField(max_length=255, null=True, blank=True) 
    postn= models.CharField(max_length=255, null=True, blank=True) 
    hisna = models.CharField(max_length=255, null=True, blank=True) 

    email = models.CharField(max_length=255, null=True, blank=True) 

    def __str__(self): 
     return self.name.encode("utf-8") 

    def get_absolute_url(self): 
     return reverse('supply-detail', args=[str(self.id)])
