django 扩展user字段

方式一:用自定义的user对象替换django中的默认

在model.py中自定义user对象
'''
自定义用户管理
'''
class MyUserManager(BaseUserManager):

def create_user(self, email, date_of_birth, device_id,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,
device_id=device_id,
)
user.set_password(password)
user.save(using=self._db)
return user

def create_superuser(self, email, date_of_birth, password,device_id):
"""
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,
device_id=device_id,
)
user.is_admin = True
user.save(using=self._db)
return user

"""
自定义用户
"""
class MyUser(AbstractBaseUser):
email = models.EmailField(
verbose_name='email address',
max_length=255,
unique=True,
)

date_of_birth = models.DateField()
#设备编号
device_id=models.CharField(max_length=10)
is_active = models.BooleanField(default=True)
is_admin = models.BooleanField(default=False)

objects = MyUserManager()
USERNAME_FIELD = 'email'
REQUIRED_FIELDS = ['date_of_birth','device_id']

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

def __str__(self): # __unicode__ on Python 2
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

在admin.py中,修改表单样式

"""
自定义用户
"""
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 = MyUser
fields = ('email', 'date_of_birth','device_id')

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


class UserChangeForm(forms.ModelForm):
"""A form for updating users. Includes all the fields on
the user, but replaces the password field with admin's
password hash display field.
"""
password = ReadOnlyPasswordHashField()

class Meta:
model = MyUser
fields = ('email', 'date_of_birth', 'is_active', 'is_admin')

def clean_password(self):
# Regardless of what the user provides, return the initial value.
# This is done here, rather than on the field, because the
# field does not have access to the initial value
return self.initial["password"]


class UserAdmin(BaseUserAdmin):
# The forms to add and change user instances
form = UserChangeForm
add_form = UserCreationForm
# The fields to be used in displaying the User model.
# These override the definitions on the base UserAdmin
# that reference specific fields on auth.User.
list_display = ('email', 'date_of_birth', 'is_admin','device_id')
list_filter = ('is_admin',)
fieldsets = (
(None, {'fields': ('email', 'password')}),
('Personal info', {'fields': ('date_of_birth','device_id',)}),
('Permissions', {'fields': ('is_admin',)}),
)
# add_fieldsets is not a standard ModelAdmin attribute. UserAdmin
# overrides get_fieldsets to use this attribute when creating a user.
add_fieldsets = (
(None, {
'classes': ('wide',),
'fields': ('email', 'date_of_birth', 'password1', 'password2','device_id')}
),
)
search_fields = ('email',)
ordering = ('email',)
filter_horizontal = ()


# Now register the new UserAdmin...
admin.site.register(MyUser, UserAdmin)
# ... and, since we're not using Django's built-in permissions,
# unregister the Group model from admin.
#admin.site.unregister(Group)

在settings.py中定义

#使用自定义用户
#AUTH_USER_MODEL = 'jkx.MyUser'

方式二:新建一个新的模型,user作为外键导入

Model.py添加

#扩展user模型
class UserProfile(models.Model):
user = models.OneToOneField(User)
description = models.TextField(max_length=51200)
scope = models.IntegerField(default=100)


def create_user_profile(sender, instance, created, **kwargs):
if created:
profile, created = UserProfile.objects.get_or_create(user=instance)


post_save.connect(create_user_profile, sender=User)

Views.py添加
#扩展user测试
def userDemo(request):
desc = User.objects.all()[0].get_profile().description
return HttpResponse(desc)

Utls.py中添加

#扩展user
url(r'^profile/',views.userDemo),

# 扩展user
class UserProfileAdmin(admin.ModelAdmin):
fields = ('user', 'description',)


admin.site.register(UserProfile, UserProfileAdmin)

修改settings.py

#扩展user
AUTH_PROFILE_MODULE='jkx.UserProfile'
