１、运行

python manage.py runserver 0.0.0.0:8000

2、添加app

在pycharm的工具栏找到 Tools，点击之后会有“Run manage.py task”选项进入终端

startapp app_name

app添加到文件夹apps下

新建apps文件夹，markas sourse root

settings.py中

import os
import sys
# Build paths inside the project like this: os.path.join(BASE_DIR, ...)
BASE_DIR = os.path.dirname(os.path.dirname(os.path.abspath(__file__)))
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))

３、生成默认数据库

在２的终端中：

makemigrations
migrate

makemigrations会记录修改的models.py,并且在migrations生成记录文件，此时数据库未作修改

migrate会把修改同步到数据库

４、添加 Django administration

python manage.py createsuperuser

root root@qq.com rootroot

访问　http://127.0.0.1:8000/admin/　进入

５、user继承AbstractUser

users app下models.py

class UserProfile(AbstractUser):
    nickname = models.CharField(max_length=50, verbose_name=u"昵称")
    birthday = models.DateField(max_length=50, null=True, blank=True, verbose_name=u"生日")
    gender = models.CharField(choices=(("male", u"男"), ("female", u"女")), default=u"female", max_length=10)
    address = models.CharField(max_length=100, default=u"")
    mobile = models.CharField(max_length=11, null=True, blank=True)
    image = models.ImageField(upload_to="images/upload/user/%y/%m", default=u"images/default/user_default.png", max_length=100)

    class Mate:
        verbose_name = u"用户信息"
        verbose_name_plural = verbose_name
        ordering = ["-id"]

    def __unicode__(self):
        return self.username

admin.py

from django.contrib import admin

# Register your models here.

from users.models import UserProfile

class UserProfileAdmin(admin.ModelAdmin):
    pass

admin.

settings.py

AUTH_USER_MODEL = "users.UserProfile"

修改之后发现后台访问报错：　'WSGIRequest' object has no attribute 'user'

修改

MIDDLEWARE　改为　MIDDLEWARE_CLASSES

６、xadmin使用

pip install xadmin
pip list

settings.py中INSTALLED_APPS添加：

    'xadmin',
    'crispy_forms',

url.py中：

import xadmin

urlpatterns = [
    url(r'^xadmin/', xadmin.site.urls),
]

之前admin.py

from django.contrib import admin

# Register your models here.

# from users.models import UserProfile
#
#
# class UserProfileAdmin(admin.ModelAdmin):
#     pass
#
# admin.site.register(UserProfile,UserProfileAdmin)

７、xadmin添加模块

在app下新建adminx.py代替admin.py

# coding=utf-8

import xadmin
from .models import EmailVerifyRecord

class EmailVerifyRecordAdmin(object):
    pass

xadmin.site.register(EmailVerifyRecord, EmailVerifyRecordAdmin)

这样就把models.py中的模块添加进后台管理

class EmailVerifyRecord(models.Model):
    code=models.CharField(max_length=20,verbose_name=u"验证码")
    email=models.EmailField(max_length=50,verbose_name=u"邮箱")
    send_type=models.CharField(verbose_name=u"发送类型",choices=(("register",u"注册"),("forget",u"忘记密码"),("update_email",u"修改邮箱")),max_length=50)
    send_time=models.DateTimeField(verbose_name=u"发送时间",default=datetime.now)

    class Meta:
        verbose_name=u"邮箱验证码"
        verbose_name_plural = verbose_name

    def __unicode__(self):
        return '{0}({1})'.format(self.code,self.email)

用户模块自动会加入，不需要添加

８、定义列表显示的字段

修改以上xadmin.py的内容

class EmailVerifyRecordAdmin(object):
    list_display = ['code', 'email', 'send_type', 'send_time']

９、定义搜索的字段

class EmailVerifyRecordAdmin(object):
   ...
    search_fields = ['code', 'email', 'send_type', 'send_time']

10、添加过滤器增强搜索

class EmailVerifyRecordAdmin(object):
...
    list_filter = ['code', 'email', 'send_type', 'send_time']
