Question

如果在基于函数的视图上permission_required失败，如何引发错误消息？我想引发错误消息，而不是重定向到登录页面，我知道如何在CBV中引发错误消息，但我不知道如何引发它在基于函数的视图中，请帮助我。谢谢，这是一个代码。

@permission_required('request.user.projectuser.change_projectusermodel')
def update(request, id):
    test = User.objects.get(id=id)
    try:
        second_form = UpdateAccountDetailForm(request.POST or None, instance=test.profile)
    except:
        second_form = UpdateAccountDetailForm(request.POST or None)

    try:
        third_form = UserRoleForm(request.POST or None, instance=test.roles)
    except:
        third_form = UserRoleForm(request.POST or None)

    if request.method == 'POST':
        form = UsersForm(request.POST, instance=test)
        form2 = second_form
        form3 = third_form
    else:
        form = UsersForm(instance=test)
        form2 = second_form
        form3 = third_form
    return save_all(request, form, form2, form3,'projectuser/update.html')

documentation section on permission_required指定了操作方法：您必须在启用了raise_exception标志的情况下调用它：@permission_required(..., raise_exception=True)

如何在基于函数的视图中引发@permission_required装饰器上的错误
