嗨，我是Django的新手
我正在使用web应用程序，登录用户可以添加客户。数据必须分两个阶段存储，一个阶段是访问细节，另一个阶段所有数据都将通过addcus保存
Visit_Detail模型是主模型，所有其他模型都有Visit_Details外键。
*****我面临的问题是如何获得Visit_detail.id的值，并将其作为外键在另一个视图中使用。**
这是我的型号

我认为这对你不起作用，但一个想法
get_post_id = Post.objects.get(name='Jhon')
print(get_post_id.id)
下面是我的建议列表：
- 您可以使用@login_required装饰器而不是request.session.has_key('is_logged'(
- 你的观点很难理解。尝试使用表单
- 要首先获取id，必须获取对象
obj = Visit_Detail.objects.get(id=pk)，然后才能获取c = Customer_Status_Detail()c.customer_visit_id = obj
我刚刚用这个更改了Visit_Detail视图
class Visit_Detail(models.Model):
date_of_visit = models.DateTimeField(auto_now_add=True)
reason_of_visit = models.CharField(max_length=200)
number_of_visitors = models.IntegerField()
visitors_added_by = models.ForeignKey(User, on_delete=models.CASCADE)
def __int__(self):
return self.id
在视图中，我刚刚做了这个
'c_visit_id = Visit_Detail.objects.latest('id')
customer_presentation_detail.customer_presentation_visit_id = c_visit_id`
并且它工作
