安装源
pip install django2.2
pip install mysqlclient1.4.6
使用pyharm 创建django 项目
django基本配置
在settings.py中设置数据库链接
DATABASES = {
'default': {
'ENGINE': 'django.db.backends.mysql',
'NAME': 'km',
'USER': 'root',
'PASSWORD': 'n4',
'HOST': 'na.cc',
'PORT': '3306'
}
}
在settings.py里面配置好端口：ALLOWED_HOSTS = ['*']
配置语言 LANGUAGE_CODE = ‘zh-hans'
配置时区TIME_ZONE = ‘Asia/Shanghai'
设置时间 USE_TZ = False
创建APP
startapp wuzhengteng
在apps中添加 ‘wuzhengteng'，
在models.py中配置数据库
from django.db import models # Create your models here. class User(models.Model): id = models.AutoField(primary_key=True) name = models.CharField(max_length=10) tel = models.CharField(max_length=11) def __str__(self): return self.name
在manage.py中执行
# 收集数据不同 makemigrations # 写入数据库 migrate # 创建超级管理员 createsuperuser
将查询写入admin
from django.contrib import admin from wuzhengteng.models import User # Register your models here. class UserAdmin(admin.ModelAdmin): list_display = ['id', 'name', 'tel'] admin.site.register(User, UserAdmin)
检查数据库是否创建成功
http://127.0.0.1:8000/admin
登入后
配置前台的用户查看界面
url路径
from django.contrib import admin
from django.urls import path
from django.views.generic import TemplateView
from wuzhengteng import views #打开views
urlpatterns = [
path('admin/', admin.site.urls),
path('', views.user, name='home') # 添加指向到views
]
配置views
from django.shortcuts import render
from .models import User # 连接数据库
# Create your views here.
def user(request):
all_user = User.objects.all() # 查询全部
return render(request, 'index.html', {
'all_user': all_user, # 将来结果返回html页面
})
前端页面
<!DOCTYPE html>
<html lang="en">
<head>
<meta charset="UTF-8">
<title>test</title>
</head>
<body>
<table border="1">
<tr>
<td>用户</td>
<td>手机</td>
</tr>
{% for post in all_user %}
<tr>
<td>{{post.name}}</td>
<td>{{post.tel}}</td>
</tr>
{% endfor %}
</table>
</body>
</html>
测试访问127.0.0.1:8000
添加用户界面
配置路由 path(‘scan', views.scan, name=“scan”)
views中插入
web页面scan.htm
def scan(request):
result = ''
if request.method == 'POST':
name = request.POST.get('name')
tel = request.POST.get('tel')
print(tel)
db = User()
db.name = name
db.tel = tel
db.save()
result = 'success'
return render(request, 'scan.html', {'result': result})
else:
return render(request, 'scan.html')
web页面scan.html
<!DOCTYPE html>
<html lang="en" xmlns="http://www.w3.org/1999/html">

views中添加
def luck(request):
all_user = User.objects.all()
return render(request, 'luck.html', {
'all_user': all_user,
})
setting里面设置静态路径
STATIC_URL = '/static/' STATICFILES_DIRS=( os.path.join(BASE_DIR,"static"), )
前端页面
