按黑马程序员的美多商场作方向:

一、应用创建、注册处理、配置
Pycharm 创建Django项目:
自应用注册处理:
二、应用数据初始化
第一步:创建元数据初始化py脚本
python manage.py makemigrations
初始化的脚本会放在各个自应用的migrates目录中
第二步:执行初始化py脚本,把表结构信息同步到数据库中
sqlite不需要建库即可实现,mysql需要先把model源信息的库建好才可以同步
python manage.py migrate
三、站点配置:
1、改成中文时区和语言编码
LANGUAGE_CODE = 'zh-hans' TIME_ZONE = 'Asia/Shanghai'
2、设置站点管理员账号
必须要先通过初始化数据之后才能执行
python manage.py createsuperuser
更改密码:
更改的密钥要求8位长度,且至少有字母和数字组成
python manage.py changepassword 用户名
3、配置自定义端口号:
#!/usr/bin/env python """Django's command-line utility for administrative tasks.""" import os import sys from django.core.management.commands.runserver import Command as RunserverCommand def main(): """Run administrative tasks.""" os.environ.setdefault('DJANGO_SETTINGS_MODULE', 'DjangoProject.settings') try: from django.core.management import execute_from_command_line except ImportError as exc: raise ImportError( "Couldn't import Django. Are you sure it's installed and " "available on your PYTHONPATH environment variable? Did you " "forget to activate a virtual environment?" ) from exc execute_from_command_line(sys.argv) if __name__ == '__main__': RunserverCommand.default_port = 9090 main()
4、站点登陆:
http://127.0.0.1:9090/admin/
5、将模型信息注册到django-admin中:
刷新页面可以发现模型信息可以直接在admin中进行管理
6、URL视图配置
工程默认会绑上django-admin的url配置
http://127.0.0.1:9090/admin/
我们可以在这里添加我们自己url配置,对应的,每个自应用也需要创建一个urls.py配置文件
内容填写,一个路由地址,对应视图的一个方法:
""" URL configuration for DjangoProject project. The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/5.0/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path, include from .views import index urlpatterns = [ path('index/', index) ]
views.py中的index方法,调用的是httpResponse进行返回:
from django.http import HttpResponse # Create your views here. def index(request): return HttpResponse("Hello, world. You're at the index page.")
访问页面进行测试:
http://127.0.0.1:9090/book_manager/index/
7、使用模版渲染处理
创建模版文件,templates为模版的路径根目录,也可以自己改成别的目录
用自应用名称区分开来,mustache语法来读取模版参数
更改index方法逻辑:
from django.http import HttpResponse from django.shortcuts import render # Create your views here. def index(request): # return HttpResponse("Hello, world. You're at the index page.") context = {'title': 'Django Book Manager'} return render(request, 'book_manager/index.html', context)
刷新查看页面:
8、上线配置ALLOW_HOSTS和关闭Debug模式
Debug模式将会把报错信息直接打印在页面上
关闭Debug模式后,仅简单输出内容
9、静态文件管理
静态文件默认配置位置(settings文件):
在Debug模式下可以直接访问:
关闭Debug模式后不能访问:
解决方案见此博客:
https://blog.csdn.net/qq_41475058/article/details/105856148
1、设置STATIC_ROOT参数
# Static files (CSS, JavaScript, Images) # https://docs.djangoproject.com/en/5.0/howto/static-files/ # 静态资源url访问路径 STATIC_URL = 'static/' # python manage.py collectstatic 收集后的资源目录位置 STATIC_ROOT = os.path.join(BASE_DIR, 'static_prod')
2、给静态目录追加url映射配置:
""" URL configuration for DjangoProject project. The `urlpatterns` list routes URLs to views. For more information please see: https://docs.djangoproject.com/en/5.0/topics/http/urls/ Examples: Function views 1. Add an import: from my_app import views 2. Add a URL to urlpatterns: path('', views.home, name='home') Class-based views 1. Add an import: from other_app.views import Home 2. Add a URL to urlpatterns: path('', Home.as_view(), name='home') Including another URLconf 1. Import the include() function: from django.urls import include, path 2. Add a URL to urlpatterns: path('blog/', include('blog.urls')) """ from django.contrib import admin from django.urls import path, include, re_path from django.views.static import serve from DjangoProject import settings urlpatterns = [ re_path(r'^static/(?P<path>.*)$', serve, {'document_root': settings.STATIC_ROOT}, name='static'), path('admin/', admin.site.urls), path('book_manager/', include('book_manager.urls')), path('my_app/', include('my_app.urls')), path('my_app2/', include('my_app2.urls')), ]
3、执行collect命令,打包静态资源
python manage.py collectstatic
