项目树

引入xadmin 

pycharm在项目中创建存放xadmin的目录

右键项目名称-->pythonpackage-->输入名称:extra_app

拷贝xadmin代码到extra_app

(mxonline) zhaijunming@zhaijuningdeMBP:~/Desktop/Project/python$ git clone  https://github.com/zaxlct/imooc-django.git
(mxonline) zhaijunming@zhaijuningdeMBP:~/Desktop/Project/python$ cp -r imooc-django/extra_apps/xadmin   MxOnline/extra_apps/.

配置settings.py

# 设置 apps, extra_apps 目录
sys.path.insert(0,os.path.join(BASE_DIR,'apps'))
sys.path.insert(0, os.path.join(BASE_DIR, 'extra_apps'))

#添加xadmin app
INSTALLED_APPS = [
    'xadmin',
    'crispy_forms',
]


LANGUAGE_CODE = 'zh-hans'

TIME_ZONE = 'Asia/Shanghai'

USE_I18N = True

USE_L10N = True

USE_TZ = False

配置url

MxOnline/urls.py

from django.conf.urls import url
from django.contrib import admin
import xadmin

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

生成数据表

makemigrations
migrate

测试

访问127.0.0.1:8000/admin

页头和页尾自定义 

随便一个项目的adminx.py中增加以下代码

from xadmin import views
 
class GlobalSetting(object):
    site_title = "慕学网后台管理系统"
    site_footer = "慕学在线网"
 
xadmin.site.register(views.CommAdminView, GlobalSetting)

左侧菜单栏样式改变

修改前

修改后

随便一个项目的adminx.py中增加以下代码

from xadmin import views
 
class GlobalSetting(object):
    site_title = "慕学网后台管理系统"
    site_footer = "慕学在线网"
    menu_style = "accordion"
 
xadmin.site.register(views.CommAdminView, GlobalSetting)

 左侧菜单栏app名称改成中文

 修改前

修改后

每一个app同理

比如users这个app

users-->apps.py

from django.apps import AppConfig


class UsersConfig(AppConfig):
    name = 'users'
    verbose_name = '用户信息'  增加这个字段,这个就是要显示的名称

users-->init.py

default_app_config = "users.apps.UsersConfig"

将models注册进xadmin

表结构(models.py)

from django.db import models
from datetime import datetime
from organization.models import *
# Create your models here.
#这里有多个表,CourseOrg(机构表),course(课程表),lesson(章节表),Video(视频表),机构和课程是一对多的关系,一个机构有多个课程,课程和章节是一对多的关系,一个课程有多个章节,章节和视频也是一对多关系,一个章节有多个视频

    choice_degree = (

        verbose_name = '视频'
        verbose_name_plural = '视频'

    def __str__(self):
        return self.name

adminx.py

import xadmin
from xadmin import views


from .models import  *

class CourseAdmin(object):
    list_display = ['course_org','name', 'desc', 'detail', 'degree','learn_times','students','fav_nums','image','click_nums','add_time']
    search_fields = ['course_org','name', 'desc', 'detail', 'degree','students','fav_nums','image','click_nums']
    list_filter = ['course_org__name','name', 'desc', 'detail', 'degree','learn_times','students','fav_nums','image','click_nums','add_time']



class LessonAdmin(object):
    list_display = ['course', 'name','add_time']
    search_fields = ['course', 'name']
    #由于lesson和course是一对多关系,一个课程有多个章节,这里的course是course 的外键,想要根据课程名称过滤章节的话,需要指定course中的一个字段,比如说name,就是根据课程名过滤属于这个课程名称的所有章节
    list_filter = ['course__name', 'name','add_time']


class VideoAdmin(object):
    list_display  = ['lesson','name','add_time']
    search_fields = ['lesson','name']
    list_filter   = ['lesson__name', 'name', 'add_time']





xadmin.site.register(Course,CourseAdmin)
xadmin.site.register(Lesson,LessonAdmin)
xadmin.site.register(Video,VideoAdmin)
#我们把course,lesson,video注册进xadmin了

效果:
