在 Django 中创建自定义模型的登录

Question

有很多方法可以在Django中实现用户身份验证。我使用模型表单来创建表单和注册过程。现在我真的不知道登录。我不能使用内置登录，因为我的模型（它被称为）和django的内置用户模型之间没有关系。我想得到一些关于方式的建议。这是我的代码：Accountviews.py:def sign_up(request):    context = {}    form = SignUpForm(request.POST or None, request.FILES or None)    if form.is_valid():        form.save()        return redirect('/')    else:        form = SignUpForm(request.POST or None, request.FILES or None)    context['form'] = form    return render(request, "sign_up.html", context)models.py:class Account(models.Model):    first_name = models.CharField(max_length=30)    last_name = models.CharField(max_length=30)    email = models.EmailField(max_length=60)    username = models.CharField(max_length=30)    password = models.CharField(max_length=60)    university_name = models.ForeignKey(        University, on_delete=models.CASCADE, blank=True, null=True)    isPhysicalAccount = models.BooleanField(default=False)    def __str__(self):        return self.usernameforms.py:lass SignUpForm(forms.ModelForm):    class Meta:        model = Account        fields = "__all__"    def __init__(self, *args, **kwargs):        super(SignUpForm, self).__init__(*args, **kwargs)

Answer 1

扩展 django 用户模型：

from django.contrib.auth.models import AbstractUser

class User(AbstractUser):

    university_name = models.ForeignKey(

        University, on_delete=models.CASCADE, blank=True, null=True)

    isPhysicalAccount = models.BooleanField(default=False)

    class Meta:

        db_table = 'auth_user'

        ordering = ('id', 'username', 'first_name', 'last_name')

settings.py：

    AUTH_USER_MODEL = 'appname.User'

要获取使用此模型的用户：

from django.contrib.auth import get_user_model

user_model = get_user_model()

user_model.objects.get(id=1)

使用您的逻辑注册视图：

from django.contrib.auth.forms import AuthenticationForm

def sign_up(request):

    context = {}

    form = AuthenticationForm(request.POST or None, request.FILES or None)

    if form.is_valid():

        form.save()

        return redirect('/')

    else:

        form = AuthenticationForm(request.POST or None, request.FILES or None)

    context['form'] = form

    return render(request, "sign_up.html", context)

举例说明如何进行自定义Account

from django.contrib.auth.base_user import AbstractBaseUser

from django.contrib.auth.models import ( PermissionsMixin, 

  _user_has_module_perms, _user_has_perm )

class Account(AbstractBaseUser, PermissionsMixin):

 first_name = models.CharField(max_length=30)

 last_name = models.CharField(max_length=30)

 email = models.EmailField(max_length=60)

 username = models.CharField(max_length=30)

 password = models.CharField(max_length=60)

 university_name = models.ForeignKey(

    University, on_delete=models.CASCADE, blank=True, null=True)

 isPhysicalAccount = models.BooleanField(default=False)

 is_admin = models.BooleanField(default=False)

 is_active = models.BooleanField(default=True)

 is_staff = models.BooleanField(default=False)

 def __str__(self):

  return self.username

 def has_perm(self, perm, obj=None):

    if self.is_active and self.is_superuser:

        return True

    return _user_has_perm(self, perm, obj)

 def has_perms(self, perm_list, obj=None):

    return all(self.has_perm(perm, obj) for perm in perm_list)

 def has_module_perms(self, app_label):

    if self.is_active and self.is_superuser:

        return True

    return _user_has_module_perms(self, app_label)

USERNAME_FIELD = 'username'

REQUIRED_FIELDS = ['username']

settings.py

AUTH_USER_MODEL = 'yourapp.Account'
