项目初始化并添加xadmin
- 创建项目 python manage.py startapp bookshop,并在配置文件中完成注册
- 根目录新建apps文件夹存放刚创建出来的项目
- 根目录新建extra_apps文件夹存放xadmin源码
python
# 添加修改settings.py
import os,sys
sys.path.insert(0, os.path.join(BASE_DIR, 'apps'))
sys.path.insert(0, os.path.join(BASE_DIR, 'extra_apps'))
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'bookshop',
'xadmin',
'crispy_forms',
'crispy_bootstrap3',
]
- 配置文件中设置项目根目录并将文件夹设置为Sources Root格式
- 新建数据库连接并完成连接配置
python
# settings.py 添加mysql连接信息
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'django_bookshops',
'USER': '用户名',
'PASSWORD': '密码',
'HOST': 'ip',
'PORT': '端口'
}
}
# 根目录下与settings.py同文件夹下__init__.py 添加如下信息
import pymysql
pymysql.install_as_MySQLdb()
- 前端文件添加
apps文件夹下新建Python Package文件命名static,在static文件夹下新建css、images、js文件夹
python
# settings.py 下添加访问静态文件路径
STATIC_URL = '/static/'
STATICFILES_DIRS = [
os.path.join(BASE_DIR,'apps','static')
]
将准备好的前端文件放在指定文件夹中,目录结构如下
python
# 修改 HTML 文件
# 顶部添加
{% load static %}
# 引入静态文件
<link href="{% static 'css/book.css' %}" rel="stylesheet">
- url路由配置
apps文件夹下的bookshop项目中新建urls.py 文件,并在根目录下与settings.py文件同目录下的urls.py文件中添加引入外部 url配置
python
# settings.py 同目录下 urls.py配置
from django.contrib import admin
from django.urls import path
# 调用其他app下定义的 url
from django.urls import include
urlpatterns = [
path('admin/', admin.site.urls),
path('home/', include('bookshop.urls'))
]
# ==============apps目录下urls.py================
from django.urls import path
from bookshop import views as bookshop_views
urlpatterns = [
# =========前端 url请求:返回页面============
path('', bookshop_views.book, name='book'),
]
- 准备数据库models类并插入数据
python
# models.py
from django.db import models
# 引入stdimage的模块
from stdimage.models import StdImageField # 字段类型
from stdimage.utils import UploadToUUID # 生成文件名

python
# 同步数据库信息
python manage.py makemigrations
python manage.py migrate
Ajax 异步请求
Ajax 即"Asynchronous JavaScript And XML"(异步 JavaScript 和 XML),是指一种创建交互式网页应用的网页开发技术。
AJAX 最大的优点是在不重新加载整个页面的情况下,可以与服务器交换数据并更新部分网页内容
- 准备图书类别的JSON数据
python
# ************定义views视图********
from django.shortcuts import render
from django.http import HttpResponse,JsonResponse
from apps.bookshop.models import *
# Create your views here.
# =============前端代码:返回页面===========
def book(request):
return render(request,'book.html')
# =============后端代码:从数据库中提取数据封装成json返回给前端===========
# 获取所有的图书类别
def get_booktype(request):
obj_booktypes = BookType.objects.all().values()
# Queryset无法直接转换成 Json,只有python基础的数据类型才可以,最外层的集合转换成列表
booktypes = list(obj_booktypes)
# 插入全部选项
booktypes.insert(0,{"id":0,"name":"全部"})
# 返回前端 json格式
return JsonResponse({'type':booktypes})
# **********定义url路由************
from django.urls import path
from bookshop import views as bookshop_views
urlpatterns = [
# =========前端 url请求:返回页面============
path('', bookshop_views.book, name='book'),
# =========后端 url请求:返回json数据========
path('booktype/get/', bookshop_views.get_booktype, name='booktype'),
]
- 将后端返回的数据展示在页面上

- 效果如下
xadmin 部署及配置
- 引入源码到项目中
javascript
# 安装xadmin的依赖包进入源码的目录
pip install -r requirements.txt
- 安装核心的包
javascript
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'bookshop',
'xadmin',
'crispy_forms',
'crispy_bootstrap3',
]
- 修改URL
python
from django.contrib import admin

python
python manage.py makemigrations
python manage.py migrate
- 设置管理员账号密码
python
python manage.py createsuperuser
- 报错问题解决
python
解决报错 render() missing 1 required positional argument: 'form_style'
1.utils.py 29行render_field()中添加form_style=None,
2.删除 detail.py 34、35行form_style
解决报错 render() missing 1 required positional argument: context
1.utils.py 66行context变为context=context
解决报错 OperationalError: (1271, "Illegal mix of collations for operation 'like'")
1.找到django包下面的\site-packages\django\db\backends\mysql\base.py文件,编辑
将icontains的值 'icontains': 'LIKE %s',改为'icontains': 'LIKE BINARY %s',
解决报错 django.template.exceptions.TemplateDoesNotExist: bootstrap3/errors.html
1.安装 pip install crispy-bootstrap3 -i https://mirrors.aliyun.com/pypi/simple/
2.注册 'crispy_bootstrap3'

图片上传功能实现
- 准备存储图片的文件夹media
- 设置MEDIA ROOT 和 MEDIA URL
python
# MEDIA ROOT:本地处理的路径,MEDIA URL: 互联网访问的路径
# settings.py
MEDIA_ROOT = os.path.join(BASE_DIR,'media')
MEDIA_URL = ''
- 配置URL
python
from django.urls import path
# 调用其他app下定义的 url
from django.urls import include
# 引入 xadmin
import xadmin
from django.conf import settings
# 匹配静态文件
from django.conf.urls.static import static
urlpatterns = [
# path('admin/', admin.site.urls),
path('xadmin/', xadmin.site.urls),
path('home/', include('bookshop.urls'))
]
# 允许所有的图片被访问
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
- 安装模块
python
pip install django-stdimage==3.2.0 -i https://mirrors.aliyun.com/pypi/simple/
- 配置models.py模版文件
python
# 引入stdimage的模块
from stdimage.models import StdImageField
# 生成唯一文件名
from stdimage.utils import UploadToUUID
# 添加图书字段
# path="" 默认存储到media下 variations缩略图配置
image = StdImageField(max_length=200, upload_to=UploadToUUID(path=""),
verbose_name='图片', variations={'thumbnail': {'width': 70, 'height': 100}})
- 更新连接表
python
python manage.py makemigrations
- 实现上传的图片在前台显示

# ====添加CKEditor配置====
# 使用默认的主题名称
CKEDITOR_CONFIGS = {
'default':
{
'toolbar': 'full',
'height': 500,
'width': 900,
},

# 上传文件存储在哪个目录 /media/uploads/

- 配置url路由
python
from django.urls import path
# 调用其他app下定义的 url
from django.urls import include
# 引入 xadmin
import xadmin
from django.conf import settings
# 匹配静态文件
from django.conf.urls.static import static

# path('admin/', admin.site.urls),
path('xadmin/', xadmin.site.urls),
# 富文本编辑器
path('ckeditor/',include('ckeditor_uploader.urls')),
path('home/', include('bookshop.urls'))
]
# 允许所有的图片被访问
urlpatterns += static(settings.MEDIA_URL, document_root=settings.MEDIA_ROOT)
- 模版models.py添加Book新字段
python
from ckeditor_uploader.fields import RichTextUploadingField
class Book(models.Model): # 图书
id = models.CharField(primary_key=True, max_length=100, null=False, verbose_name='编号') # 编号,主键
name = models.CharField(max_length=100, null=False, verbose_name='名称') # 名称
barcode = models.CharField(max_length=100, null=False, verbose_name='条形码') # 条形码
type = models.ForeignKey("BookType", on_delete=models.CASCADE, verbose_name='类别') # 类别
press = models.ForeignKey("Press", on_delete=models.CASCADE, verbose_name='出版社') # 出版社
author = models.ForeignKey("Author", on_delete=models.CASCADE, verbose_name='作者') # 作者
price = models.FloatField(null=False, verbose_name='单价') # 价格
difficulty = models.CharField(max_length=100,null=False, verbose_name='难易程度') # 难易程度: 0--入门 1--中级 2--高级
# path="" 默认存储到media下 variations缩略图配置
image = StdImageField(max_length=200, upload_to=UploadToUUID(path=""),
verbose_name='图片', variations={'thumbnail': {'width': 70, 'height': 100}}
)

storage_in_num = models.IntegerField(null=False, verbose_name='入库量') # 入库量
storage_in_date = models.DateField(null=False, verbose_name='入库时间') # 入库时间
inventory_num = models.IntegerField(null=False, verbose_name='库存量') # 库存量
# 添加富文本编辑器字段
detail = RichTextUploadingField(verbose_name="图书详情",default="")
class Meta:
verbose_name = "图书"
verbose_name_plural = "图书"
def __str__(self):
return "%s" % self.name
- 同步数据
python
python manage.py makemigrations
python manage.py migrate
- 将富文本内容展示在前端页面
python
//把图书的详情展示在页面
$('.detail').html(book.detail);
