git:https://github.com/huangantai/todolist.git

1、

pip install django=='2.1'

django-admin startproject todolist

django-admin startapp simpletodo

pip install https://codeload.github.com/sshwsfc/xadmin/zip/django2

2、settings.py 和 urls.py 设置

settings.py (注释csrf中间件)

ALLOWED_HOSTS = ['*'] INSTALLED_APPS = [ 'django.contrib.admin', 'django.contrib.auth', 'django.contrib.contenttypes', 'django.contrib.sessions', 'django.contrib.messages', 'django.contrib.staticfiles', 'simpletodo', 'xadmin', 'crispy_forms', 'reversion', ] LANGUAGE_CODE = 'zh-Hans' TIME_ZONE = 'Asia/Shanghai' TEMPLATES = [ { 'BACKEND': 'django.template.backends.django.DjangoTemplates', 'DIRS': [os.path.join(BASE_DIR, 'templates')], 'APP_DIRS': True, 'OPTIONS': { 'context_processors': [ 'django.template.context_processors.debug', 'django.template.context_processors.request', 'django.contrib.auth.context_processors.auth', 'django.contrib.messages.context_processors.messages', ], }, }, ] STATIC_URL = '/static/' STATIC_ROOT = os.path.join(BASE_DIR, '/static/')

urls.py

from django.urls import path,include from simpletodo import views import xadmin xadmin.autodiscover()

from xadmin.plugins import xversion xversion.register_models()

urlpatterns = [ path('admin/', xadmin.site.urls), path(r'', views.todolist), path(r'simpletodo/',include('simpletodo.urls')) ]

python manage.py makemigrations python manage.py migrate python manage.py createsuperuser python manage.py collectstatic

3、simpletodo/models.py adminx.py urls.py views.py

models.py

from django.db import models from django.contrib.auth.models import User

Create your models here.

class Todo(models.Model): id=models.AutoField(primary_key=True) user = models.ForeignKey(User,on_delete=models.CASCADE) todo = models.CharField(max_length=50) flag = models.CharField(max_length=2) priority = models.CharField(max_length=2) pubtime = models.DateTimeField(auto_now_add=True)

def __unicode__(self):
    return u'%d %s %s' % (self.id, self.todo, self.flag)

class Meta:
    ordering = ['priority', 'pubtime']

adminx.py

import xadmin from simpletodo.models import Todo

Register your models here.

class TodoAdmin(object): list_display = ['user', 'todo', 'priority', 'flag', 'pubtime'] list_filter = ['pubtime','priority'] ordering = ['-pubtime'] list_editable=['todo','priority','flag']

xadmin.site.register(Todo, TodoAdmin) [root@centos8 simpletodo]# vi adminx.py [root@centos8 simpletodo]# cat adminx.py from xadmin import views import xadmin

class BaseSetting(object): """xadmin的基本配置""" enable_themes = True # 开启主题切换功能 use_bootswatch = True

class GlobalSettings(object): """xadmin的全局配置""" site_title = "todolist" # 设置站点标题 site_footer = "-todolist-" # 设置站点的页脚 menu_style = "accordion" # 设置菜单折叠

xadmin.site.register(views.CommAdminView, GlobalSettings) xadmin.site.register(views.BaseAdminView, BaseSetting)

from simpletodo.models import Todo

Register your models here.

class TodoAdmin(object): list_display = ['user', 'todo', 'priority', 'flag', 'pubtime'] list_filter = ['pubtime','priority'] ordering = ['-pubtime'] list_editable=['todo','priority','flag']

xadmin.site.register(Todo, TodoAdmin)

4、templates/simpletodo.html updatatodo.html showtodo.html

simpletodo.html

css

bootstrap.min.css

img

glyphicons-halflings.png glyphicons-halflings-white.png

js

ajaxpost.js bootstrap.js bootstrap.min.js jquery.js modernizr.js Tex parse error/.test(method)); }

if (!safeMethod(settings.type) && sameOrigin(settings.url)) {
    xhr.setRequestHeader("X-CSRFToken", getCookie('csrftoken'));
}

});

6、修改settings.py

STATIC_ROOT = os.path.join(BASE_DIR, '/static')

STATICFILES_DIRS = [os.path.join(BASE_DIR,'static'),] 7、 python manage.py makemigrations python manage.py migrate python runserver 0.0.0.0:9999 &
