我按照此tutorial创建了自定义User。
在views.py中，我创建了一个方法来预先显示userid（即/ users / 42）的用户信息，但结果为AnonymousUser。我应该提一下我想要获得的数据库记录存在于我的数据库中。
这是我的models.py文件：
from django import forms
from django.db import models
from django.contrib.auth.models import AbstractBaseUser, BaseUserManager
from django.contrib.auth.forms import UserCreationForm
class UserProfileManager(BaseUserManager):
def create_user(self, email, date_of_birth, 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),
date_of_birth=date_of_birth,
)
user.set_password(password)
user.save(using=self._db)
return user
def create_superuser(self, email, date_of_birth, password):
"""
Creates and saves a superuser with the given email, date of
birth and password.
"""
user = self.create_user(email,
password=password,
date_of_birth=date_of_birth
)
user.is_admin = True
user.save(using=self._db)
return user
class UserProfile(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
db_index=True,
)
date_of_birth = models.DateField()
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)
objects = UserProfileManager()
USERNAME_FIELD = 'email'
#REQUIRED_FIELDS = ['date_of_birth']
def get_full_name(self):
# The user is identified by their email address
return self.email
def get_short_name(self):
# The user is identified by their email address
return self.email
# On Python 3: def __str__(self):
def __unicode__(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
class UserCreationForm(forms.ModelForm):
"""A form for creating new users. Includes all the required
fields, plus a repeated password."""
password1 = forms.CharField(label='Password', widget=forms.PasswordInput)
password2 = forms.CharField(label='Password confirmation', widget=forms.PasswordInput)
class Meta:
model = UserProfile
fields = ('email', 'date_of_birth')
def clean_password2(self):
# Check that the two password entries match
password1 = self.cleaned_data.get("password1")
password2 = self.cleaned_data.get("password2")
if password1 and password2 and password1 != password2:
raise forms.ValidationError("Passwords don't match")
return password2
def save(self, commit=True):
# Save the provided password in hashed format
user = super(UserCreationForm, self).save(commit=False)
user.set_password(self.cleaned_data["password1"])
if commit:
user.save()
return user
以下是展示User的方法：
def show_user(request, user_id):
try:
user = UserProfile.objects.get(id=user_id)
except UserProfile.DoesNotExist:
return None
template = loader.get_template('index.html')
context = RequestContext(request, {
'user': user,
})
return HttpResponse(template.render(context))

django.contrib.auth.context_processors.auth将user变量注入上下文数据，上下文处理器注入的变量可以覆盖提供给RequestContext的变量。
应用上下文处理器时
使用RequestContext时，您直接提供的变量是 首先添加，跟随上下文处理器提供的任何变量。 这意味着上下文处理器可能会覆盖您的变量 提供，所以要小心避免重叠的变量名称 那些由你的上下文处理器提供的。
