浅谈Python之Django 浅谈Python之Django(四)
z-victor 人气:01.pip3 install xadmin
因为我是django2.0,直接使用命令一直报错,如下图
2.解决方案
下载xadmin源包
下载地址:https://github.com/Zjvngvn/xadmin
pip3 install 源码的地址(不用解压) 如:pip3 install
E:\firefoxDownload\xadmin-django2.zip
3. 修改配置文件setting.py中的INSTALLED_APPS
添加 xadmin
crispy_forms
INSTALLED_APPS = [
‘django.contrib.admin',
‘django.contrib.auth',
‘django.contrib.contenttypes',
‘django.contrib.sessions',
‘django.contrib.messages',
‘django.contrib.staticfiles',
‘users',
‘course',
‘organization',
‘operation',
‘xadmin',
‘crispy_forms'
]
4.修改urls中的路由
from django.contrib import admin from django.urls import path import xadmin urlpatterns = [ # path('admin/', admin.site.urls), path('xadmin/', xadmin.site.urls), ]
5.访问
重启:python manage.py runserver 0.0.0.0:8888
http://127.0.0.1:8888/xadmin
6.设置显示的字段与搜索的字段
在users App下创建xadmin.py 文件
添加如下代码
import xadmin from .models import EmailVerifyRecord,Banner class EmailVerifyRecordAdmin(object): # 列表显示的字段 list_display = ['code','email','send_type','send_time'] # 搜索字段 # search_fields = ['code','email'] # 搜索字段 list_filter = ['code','email','send_type','send_time'] class BannerAdmin(object): # title = models.CharField(max_length=100, verbose_name=u"标题") # image = models.ImageField(max_length=100, upload_to="banner/%Y/%m", verbose_name=u"轮播图") # url = models.URLField(max_length=100, verbose_name=u"访问地址") # index = models.IntegerField(verbose_name=u"顺序", default=100) # add_time = models.DateTimeField(default=datetime.now, verbose_name=u"添加时间") list_display = ['title', 'url', 'index', 'add_time'] xadmin.site.register(EmailVerifyRecord,EmailVerifyRecordAdmin) xadmin.site.register(Banner,BannerAdmin)
在course App下创建xadmin.py 文件
添加如下代码
import xadmin from .models import Course,Lesson,Video,CourseResource class CourseAdmin(object): list_display = ['name', 'desc', 'detail', 'degree','learn_time','students','fav_nums','click_nums'] # # 搜索字段 # # search_fields = ['code','email'] # # 搜索字段 # list_filter = ['code', 'email', 'send_type', 'send_time'] class LessonAdmin(object): list_display = ['course', 'name', 'add_time'] # 搜索字段 search_fields = ['course','name','add_time'] list_filter = 'course','name','add_time' class VideoAdmin(object): list_display = ['lesson', 'name', 'add_time'] class CourseResourceAdmin(object): list_display = ['course', 'name', 'download','add_time'] xadmin.site.register(Course,CourseAdmin) xadmin.site.register(Lesson,LessonAdmin) xadmin.site.register(Video,VideoAdmin) xadmin.site.register(CourseResource,CourseResourceAdmin)
搜索外键课程
搜索外键 外键名称为course 在class Course为name,用__拼接course与name就可以对外键进行搜索了
将course App的class Course中的list_filter改成如下代码:
list_filter = 'course__name','name','add_time'
添加章节的时候出现了如下问题该怎么解决???
7.__str __
在course App的models.py的class Course中加上如下代码
def __str__(self): return self.name
__str__是python的object基类的一个方法,也就是说python所有的类都有,当然django的modle类也有,我们平常创建一个类的对象,print这个对象时一般会是<_main.TestClass
object at
0x7f4126578828>,即这个对象的所属类和内存地址,我们改写类中的__str__方法后可以在print时得到想要的易于人阅读的对象的信息
在Django中,如果用的是Python3的话就只能用__str__方法,如果是Python2的话就使用__unicode__方法。因为更安全一些。看看文档
8.全局配置
users App下adminx.py的代码如下:
import xadmin from .models import EmailVerifyRecord,Banner from xadmin import views class BaseSetting(object): enable_themes = True use_bootswatch = True class GlobalSettings(object): site_title = '慕学后台管理系统' site_footer = '慕学在线网' menu_style = 'accordion' class EmailVerifyRecordAdmin(object): # 列表显示的字段 list_display = ['code','email','send_type','send_time'] # 搜索字段 # search_fields = ['code','email'] # 搜索字段 list_filter = ['code','email','send_type','send_time'] class BannerAdmin(object): # title = models.CharField(max_length=100, verbose_name=u"标题") # image = models.ImageField(max_length=100, upload_to="banner/%Y/%m", verbose_name=u"轮播图") # url = models.URLField(max_length=100, verbose_name=u"访问地址") # index = models.IntegerField(verbose_name=u"顺序", default=100) # add_time = models.DateTimeField(default=datetime.now, verbose_name=u"添加时间") list_display = ['title', 'url', 'index', 'add_time'] xadmin.site.register(EmailVerifyRecord,EmailVerifyRecordAdmin) xadmin.site.register(Banner,BannerAdmin) xadmin.site.register(views.BaseAdminView,BaseSetting) xadmin.site.register(views.CommAdminView,GlobalSettings)
让后台可以显示多种样式
class BaseSetting(object):
enable_themes = True
use_bootswatch = Truexadmin.site.register(views.BaseAdminView,BaseSetting)
修改后台名称
添加如下代码:
class GlobalSettings(object): site_title = '慕学后台管理系统' xadmin.site.register(views.CommAdminView,GlobalSettings)
修改页脚
class GlobalSettings(object): site_footer = '慕学在线网'
修改菜单显示样式
class GlobalSettings(object): menu_style = 'accordion'
将英文菜单设置为中文菜单
修改users App下的apps.py文件为如下代码:
class UsersConfig(AppConfig): name = 'users' verbose_name = u'用户信息'
修改users App下的__init__.py文件为如下代码:
default_app_config = "users.apps.UsersConfig"
