要想自定義用戶認(rèn)證的話垄开，首先UserProfile賬戶表不能再與django的User表OneToOne關(guān)聯(lián)了希柿，djangoproject網(wǎng)址提供了我們重新自定義的實(shí)現(xiàn)方法等孵，先來到這個(gè)網(wǎng)站https://docs.djangoproject.com/en/2.1/topics/auth/customizing/窘疮，ctrl+F找到 MyUser這個(gè)類

class UserProfile(AbstractBaseUser):
    email = models.EmailField(
        verbose_name='email address',
        max_length=255,
        unique=True,
    )

    name = models.CharField(max_length=32)
    is_active = models.BooleanField(default=True)
    is_admin = models.BooleanField(default=False)

    objects = UserProfileManager()

    USERNAME_FIELD = 'email'
    REQUIRED_FIELDS = ['name']

    def __str__(self):
        return self.email

    def has_perm(self, perm, obj=None):
        "Does the user have a specific permission?"
        # Simplest possible answer: Yes, always
        return True

    def has_module_perms(self, app_label):
        "Does the user have permissions to view the app `app_label`?"
        # Simplest possible answer: Yes, always
        return True

    @property
    def is_staff(self):
        "Is the user a member of staff?"
        # Simplest possible answer: All admins are staff
        return self.is_admin

如果你的數(shù)據(jù)庫前面已經(jīng)有數(shù)據(jù)了接奈，那就得先刪庫了(目前只會的操作)哪雕。刪完庫后開始makemigrations二連，現(xiàn)在就可以創(chuàng)建一個(gè)超級用戶進(jìn)入admin了鲫趁。但是斯嚎，，挨厚，點(diǎn)擊 UserProfile 表報(bào)錯(cuò)堡僻，沒找到，

是因?yàn)閐jango不知道哪個(gè)是賬戶表疫剃，可能有人說UserProfile不是繼承了一個(gè) AbstractBaseUser 類嗎钉疫？AbstractBaseUser也僅僅只是一個(gè)model類，沒法做到這個(gè)巢价，現(xiàn)在我們要去settings里明確地告訴 django 牲阁，哪個(gè)是我的用戶表固阁。在settings最末尾加上AUTH_USER_MODEL = 'crm.UserProfile'就可以了，crm是app名字

現(xiàn)在我們再重新來一遍migrate,會報(bào)出下面的警告城菊，意思是需不需要把django自己的User表給刪掉备燃，我們敲上yes就行

class UserProfileManager(BaseUserManager):
    def create_user(self, email, name, password=None):
        """
        Creates and saves a User with the given email, date of
        birth and password.
        """
        if not email:
            raise ValueError('Users must have an email address')

        user = self.model(
            email=self.normalize_email(email),
            name=name,
        )
        user.is_active = True
        user.set_password(password)
        user.save(using=self._db)
        return user

    def create_superuser(self, email, name, password):
        """
        Creates and saves a superuser with the given email, date of
        birth and password.
        """
        user = self.create_user(
            email,
            password=password,
            name=name,
        )
        user.is_admin = True
        user.save(using=self._db)
        return user

這個(gè)時(shí)候我們在MyUser里注釋的objects就得解開了！
現(xiàn)在需要繼續(xù)makemigrations了熬北，可有有時(shí)候會保一個(gè)django_admin_log的錯(cuò)誤疙描，只需要在migrate后面加上--fake诚隙。


不過不會顯示UserProfile表讶隐，只有在admin中加上下面代碼，才能夠?qū)Ρ磉M(jìn)行操作久又，這段代碼在djangoproject中也有
