当管理员登录时，我正在尝试编辑特定用户的用户详细信息，但是当我按下更新按钮时，它没有更新而不显示任何错误消息。(如果我错了，请纠正我(。

这是编辑方法 view.py
def edit(request, emp_id):
if request.method == 'POST':
emp = employee.objects.get(pk=emp_id)
form = EmployeForm(request.POST or None, instance=emp)
if form.is_valid():
form.save()
messages.success(request, ('Item has been edited'))
return HttpResponseRedirect('view_profile')
else:

def view_profile(request):
employees = employee.objects.all()
args= {'user':request.user,'employees':employees}
return render(request,'profile.html',args)
这是我的模型页面
class employee(models.Model):
user = models.OneToOneField(User, on_delete=models.CASCADE)
first_name = models.CharField(max_length=50)
last_name = models.CharField(max_length=50)
email = models.EmailField(max_length=50)
gender = models.CharField(max_length=1,choices=(('M','Male'),
('F','Female')),blank=True)
age = models.PositiveIntegerField(blank=True, null=True)
salary = models.CharField(blank = True,max_length=50
def __str__(self):
return self.user.username
请提供有关如何故障排除的任何建议或我可以阅读的任何文档。
您没有正确使用表单。表单不仅用于验证，还负责呈现错误消息。您希望更改视图以将表单传递到模板：
def edit(request, emp_id):
emp = employee.objects.get(pk=emp_id)
if request.method == 'POST':
form = EmployeForm(request.POST, instance=emp)
if form.is_valid():
form.save()
messages.success(request, ('Item has been edited'))
# this one is probably not going to work
# as expected - you may want to check the
# doc for the `redirect` shortcut instead
return HttpResponseRedirect('view_profile')
else:
form = EmployeForm(instance=emp)
return render(request, 'edit.html', {'emp': emp, 'form':form})
然后在模板中，不要手动编写整个表单标记，而是使用表单进行呈现，以便正确显示验证错误。
