Python 如何使用django ModelForm对象和Queryset执行登录身份验证功能

我下面的问题是关于如何开发一个函数来比较请求后数据（

ModelForm

）和

queryset

中模型的现有数据

这是mi models.py：

class Employee(models.Model):
    dni = models.CharField(max_length=9, null=False, blank=False, default="12345678R")
    name = models.CharField(max_length=7)
    surname = models.CharField(max_length=8)
    email = models.CharField(max_length=20)
    telefone_number = models.IntegerField()
    user_nick = models.CharField(max_length=10, null=False, blank=False, default="user")
    password = models.CharField(max_length=20, null=False, blank=False, default="password")
    ticket = models.ManyToManyField(Ticket)

forms.py（EmployerLoginForm仅适用于

用户_nick

和

密码

）：

在本例中，为了开发登录功能，我使用views.py中的

EmployerLoginForm

：

_logger = nexus_services_logs.Logging(statics.NEXUS_VIEWS_LOGGING_NAME)
_views_manager_service = nexus_services_views_manager.ViewsManagerService()
_auth = nexus_services_auth.Authentication()

class IndexView(View):

    def post(self, request, *args, **kwargs):
        form = EmployerLoginForm(request.POST)
        if(_auth.check_model_employer_authentication(form, _logger, _views_manager_service)):
            if(_views_manager_service.validate_form(form, _logger)):
                _views_manager_service.save_form(form, _logger)
            return redirect('employerPortal')
        else:
            return redirect('index')

check\u model\u employer\u authentication（表单、\u logger、\u views\u manager\u service）

是我想要比较表单数据和查询集的功能。当我无法使用for循环比较对象时（在

auth.py

中），我发现了问题：

我尝试过使用上下文，但不起作用。

什么不起作用？你是否面临任何错误。回溯在哪里？在if语句的行中是：if（employer.user\u nick==model.user\u nick和employer.password==model.password）。我认为这是因为表单对象无法获取用户身份和密码。什么不起作用？你是否面临任何错误。回溯在哪里？在if语句的行中是：if（employer.user\u nick==model.user\u nick和employer.password==model.password）。我认为这是因为表单对象无法获取用户身份和密码。

        else:

                return True
            else:
                logger.error_log("Nick or password not exist or coincidence with object in db")
                return False
