django-admin startproject demo02 #创建工程
cd demo02
#设置工程 demo02 总路 urls.py 由分发,至app应用下路由urls
python manage.py startapp xtt #创建应用
进入web1 创建 urls.py
编辑xtt应用下的urls.py #编辑应用下的urls
from django.urls import re_path
from django.shortcuts import HttpResponse
from xtt import views
urlpatterns = [
re_path('sub/', views.sub )
]
编辑xtt应用下的views.py #编辑应用下的views.py
from django.shortcuts import render
from django.shortcuts import HttpResponse
def sub(request):
dic = {"xuesheng" : "xiaoming", "nianing":27,}
return HttpResponse(dic.items())
编辑demo02项目下的setting.py,将新建应用xtt,添加进去
INSTALLED_APPS = [
'django.contrib.admin',
'django.contrib.auth',
'django.contrib.contenttypes',
'django.contrib.sessions',
'django.contrib.messages',
'django.contrib.staticfiles',
'xap',
'xtt',
]
编辑demo02项目下的urls.py,将总路由,分发至各个应用下xtt的urls.py
from django.contrib import admin
from django.urls import path, include
urlpatterns = [
path('admin/', admin.site.urls),
path('xap/', include("xap.urls")),
path('xtt/', include("xtt.urls")),
]
python manage.py runserver #启动应用
- - - - - - - 此处简单的python项目,已启动,可以测试了 - - - - - - - - - - - -
后续 ...,导入html
在与settings.py同级目录下的__init__.py中引入模块和进行配置,用于加载数据库驱动
import pymysql
pymysql.install_as_MySQLdb()
# 设置html,数据与图片静态分离
在demo2项目下,新建templates的python包,并创建各个一个用对应的html
编辑demo02项目下的setting.py,将DIRS的[],添加'DIRS': [os.path.join(BASE_DIR, 'templates')],
TEMPLATES = [
{
'BACKEND': 'django.template.backends.django.DjangoTemplates',
'DIRS': [],
'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',
],
},
},
]
现在开始编写 xtt应用的 views.py ,通过render函数,把数据渲染到 html 上
'''
from django.shortcuts import render
from django.shortcuts import HttpResponse
def sub(request):
dic = {"xuesheng" : "xiaoming", "nianing":27,}
return HttpResponse(dic.items())
'''
#字典获取方式
from django.shortcuts import render
def sub(request):
context = {}
context['hello'] = 'Hello World!'
return render(request, 'xtt.html', context)
修改 templates下的 xtt.html, 主要是获取 {
{ hello }}数据
#字符串获取方式
views.py中
from django.shortcuts import render
def sub(request):
str = "xuesheng"
return render(request, 'xtt.html', {"str":str})
xxt.html中
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>xtt数据</title>
</head>
<body>
<p> {
{ str }} </p>
</body>
</html>
