I am creating a django project involving multiple types of users. For that, I have not created new User classes, rather I have just extended the model using a OneToOne relation (like we do while creating a profile model). Model in one app is like this:

我正在创建一个Django项目，涉及多种类型的用户。为此，我没有创建新的用户类，而只是使用ONEtoONE关系扩展了模型(就像我们在创建概要文件模型时所做的那样)。一款应用中的模型是这样的：

class Dev(models.Model):
    user = models.OneToOneField(User, on_delete = models.CASCADE)
    BaseSkills = models.ManyToManyField(ProjectBaseSkills,
        help_text='Adding Base skills help us to identify the best projects for you', blank=True)
    PhoneNumber = models.BigIntegerField(
        help_text="Don't add the country code (the user base is restricted to India for now)")

    def __str__(self):
        return f'{self.user.first_name} {self.user.last_name}'

and in the other app is like this:

在另一款应用中是这样的：

class Hirer(models.Model):
    user = models.OneToOneField(User, on_delete=models.CASCADE)
    Name = models.CharField(max_length=120, default='Hirer')
    PhoneNumber = models.BigIntegerField(blank=True)

This shows how there are two types of users: Devs and Hirers.
Now since there are multiple user types, I need to redirect the different users to different urls after login, so I can't just rely on the LOGIN_REDIRECT_URL settings. Also I don't want to define a login view myself, so I am using the default LoginView from django auth.
Here is the urls.py for the app where Dev user is used:

这显示了如何有两种类型的用户：开发者和雇佣者。现在由于有多种用户类型，我需要在登录后将不同的用户重定向到不同的URL，所以我不能只依赖LOGIN_REDIRECT_URL设置。我也不想自己定义登录视图，所以我使用django auth的默认LoginView。以下是使用Dev用户的应用程序的urls.py：

from django.urls import path
from django.conf import settings
from django.conf.urls.static import static
from django.contrib.auth import views as auth_views
from . import views

urlpatterns = [
    path('login/', auth_views.LoginView.as_view(template_name='dev_user/login.html'), name='dev-login'),
    path('register/', views.Register, name='dev-register')
] + static(settings.MEDIA_URL, document_root =settings.MEDIA_ROOT)

And the one where Hirer user is used:

和使用Hirer用户的版本：

from django.urls import path
from django.contrib.auth import views as auth_views
from django.conf import settings
from django.conf.urls.static import static
from . import views

urlpatterns = [
    path('login/', auth_views.LoginView.as_view(template_name='client_user/login.html'), name='client-login'),
    path('register/', views.Register, name='client-register'),
] + static(settings.MEDIA_URL, document_root =settings.MEDIA_ROOT)

In the documentation (https://docs.djangoproject.com/en/3.0/topics/auth/default/#django.contrib.auth.views.LoginView) it is said that we can override the redirect url by using the redirect_field_name in GET field of the LoginView. But there's not example code or something, and I'm quite new at programming, so I don't know how to do that. There are also no examples on the net, so please someone help me out here.

在文档(https://docs.djangoproject.com/en/3.0/topics/auth/default/#django.contrib.auth.views.LoginView)中，我们可以通过在登录视图的GET字段中使用REDIRECT_FIELD_NAME来覆盖重定向URL。但是没有示例代码之类的东西，而且我对编程还很陌生，所以我不知道该怎么做。网上也没有这样的例子，所以请谁来帮帮我。

I am grateful to all the people who answered. Though my original query was not solved, I did find a get around to do a login. Here's what I did for others to implement if they're stuck in a similar situation:
(views.py):

我感谢所有回答问题的人。虽然我最初的问题没有得到解决，但我确实找到了一个办法来登录。以下是我为其他人在遇到类似情况时所做的实现：(views.py)：

def Login(request):
    if request.method == 'POST':
        username = request.POST.get('username')
        password = request.POST.get('password')
        user = authenticate(username=username, password=password)
        if user is not None:
            login(request, user)
            return redirect('dev-profile')

    return render(request, 'client_user/login.html')

Also if you have an answer to the original query, please do answer!

另外，如果你对原来的问题有答案，请一定要回答！

You can try something like this (in your views):

您可以尝试这样的操作(在您的观点中)：

@login_required
def custom_redirect(request):
   if request.user.dev.filter(BaseSkills='xxx'):
       return redirect('xxx')
   elif request.user.dev.filter(BaseSkills='xxx'):
       return redirect('xxx')

Also note that best practise is to have model field names in lowercase, using underscores instead of camelCase.

另请注意，最佳做法是使用小写的模型字段名称，使用下划线而不是CamelCase。

This is how I could change the redirect_field_name:

以下是我更改REDIRECT_FIELD_NAME的方法：

return login_required(view_func, redirect_field_name="return_to")(request, *view_args, **view_kwargs)

Full Sample code:

完整的示例代码：

from django.contrib.auth.decorators import login_required


def login_exempt(view):
    view.login_exempt = True
    return view


class LoginRequiredMiddleware:
    def __init__(self, get_response):
        self.get_response = get_response

    def __call__(self, request):
        return self.get_response(request)

    def process_view(self, request, view_func, view_args, view_kwargs):
        if getattr(view_func, 'login_exempt', False):
            return

        if request.user.is_authenticated:
            return

        return login_required(view_func, redirect_field_name="return_to")(request, *view_args, **view_kwargs)
