使用django自带的user做外键的方法

时间:2021-05-22

一、使用django自带的user做外键,可以直接在model中使用。只需导入settings模块

使用方法:
在app应用(此处是Product应用)中的models.py文件,导入settings模块

# Product / models.pyfrom django.db import modelsfrom django.contrib.auth import settingsclass Product(models.Model): productName = models.CharField('产品名称', max_length=20) productDescription = models.CharField('产品描述', max_length=100) producer = models.ForeignKey(settings.AUTH_USER_MODEL, verbose_name='负责人', on_delete=models.SET_NULL,blank=True, null=True) createTime = models.DateTimeField('创建时间', auto_now=True) class Meta: verbose_name = '产品管理' verbose_name_plural = '产品管理' def __str__(self): return self.productName

二、自定义User Model

方法一、扩展AbstractUser类:只增加字段

app/models.py

from django.contrib.auth.models import AbstractUserfrom django.db import modelsclass NewUser(AbstractUser): new_field = models.CharField(max_length=100)

同时,需要在global_settings文件中设置:

AUTH_USER_MODEL = "app.NewUser"

方法二、扩展AbstractBaseUser类
AbstractBaseUser中只包含3个field: password, last_login和is_active. 扩展方式同上

# django.contrib.auth.base_userclass AbstractBaseUser(models.Model): password = models.CharField(_('password'), max_length=128) last_login = models.DateTimeField(_('last login'), blank=True, null=True) is_active = True REQUIRED_FIELDS = [] # Stores the raw password if set_password() is called so that it can # be passed to password_changed() after the model is saved. _password = None class Meta: abstract = True def __str__(self): return self.get_username() def save(self, *args, **kwargs): super().save(*args, **kwargs) if self._password is not None: password_validation.password_changed(self._password, self) self._password = None def get_username(self): """Return the username for this User.""" return getattr(self, self.USERNAME_FIELD) def clean(self): setattr(self, self.USERNAME_FIELD, self.normalize_username(self.get_username())) def natural_key(self): return (self.get_username(),) @property def is_anonymous(self): """ Always return False. This is a way of comparing User objects to anonymous users. """ return False @property def is_authenticated(self): """ Always return True. This is a way to tell if the user has been authenticated in templates. """ return True def set_password(self, raw_password): self.password = make_password(raw_password) self._password = raw_password def check_password(self, raw_password): """ Return a boolean of whether the raw_password was correct. Handles hashing formats behind the scenes. """ def setter(raw_password): self.set_password(raw_password) # Password hash upgrades shouldn't be considered password changes. self._password = None self.save(update_fields=["password"]) return check_password(raw_password, self.password, setter) def set_unusable_password(self): # Set a value that will never be a valid hash self.password = make_password(None) def has_usable_password(self): """ Return False if set_unusable_password() has been called for this user. """ return is_password_usable(self.password) def get_session_auth_hash(self): """ Return an HMAC of the password field. """ key_salt = "django.contrib.auth.models.AbstractBaseUser.get_session_auth_hash" return salted_hmac(key_salt, self.password).hexdigest() @classmethod def get_email_field_name(cls): try: return cls.EMAIL_FIELD except AttributeError: return 'email' @classmethod def normalize_username(cls, username): return unicodedata.normalize('NFKC', username) if isinstance(username, str) else username
