我只想在（他們使用 vendorform 注冊）時為供應商用戶生成一個 customID（以 VEND0001 開頭），并且不應該為客戶和超級用戶生成 customid。我在模型中有錯誤。有人可以請幫我解決這個問題。
我遇到了問題（唯一約束失敗：customer_customuser.userid）。
uj5u.com熱心網友回復：
也許我錯了，但我認為當你這樣做時：
def save(self, *args, **kwargs):
super().save(*args, **kwargs)
if self.vendor == True and self.is_superuser == False:
if not self.userid:
self.userid = "VEN" str(self.id (10 ** 5)) # generating the uid and allocating the value
self.userid.save()
else:
pass
else:
pass
在 super().save 中沒有必須的用戶 ID 資訊。也許userid= models.CharField(max_length=100, unique=True, null=True)會起作用……但請注意 NULL != NULL。
然后
if not self.userid改為if self.userid is None:
