我想从1开始id。
每当一行被删除时,它就会跳过那个数字并跳到下一个数字。
就像在这张图中一样,它跳过了1-6和8之间的数字。
我想将其设置为1,2,3
这是我的模型
class dish(models.Model):
id = models.AutoField(primary_key=True)
dish_id = models.AutoField
dish_name = models.CharField(max_length=255, blank=True, null=True)
dish_category = models.CharField(max_length=255, blank=True, null=True)
dish_size = models.CharField(max_length=7, blank=True, null=True)
dish_price = models.IntegerField(blank=True, null=True)
dish_description = models.CharField(max_length=255, blank=True, null=True)
# dish_image = models.ImageField(upload_to="images/", default=None, blank=True, null=True)
dish_image = models.ImageField(upload_to="media/", default=None, blank=True, null=True) #here added images as a foldername to upload to.
dish_date = models.DateField()
def __str__(self):
return self.dish_name
这是views.py
def delete(request, id):
dishs = dish.objects.get(id=id)
dishs.delete()
return HttpResponseRedirect(reverse('check'))
