第一步:下载mysql驱动
cmd进入创建好的django项目目录：然后使用下面的命令创建一个项目testdj。
第二步:在settings.py中配置mysql连接参数（没有mysql的先装mysql）
DATABASES = { 'default': { 'ENGINE': 'django.db.backends.mysql', 'NAME': '数据库名(你得先在mysql中创建数据库)', 'USER':'mysql用户名（如root）', 'PASSWORD':'密码（如123456789）', 'HOST':'域名（127.0.0.1或localhost）', 'PORT':'端口号（3306）', }}第三步：在models.py中创建model类
1、cmd进入django项目路径下
2、Python manage.py migrate #创建表结构，非model类的其他表，django所需要的
3、python manage.py makemigrations app名 #做数据迁移的准备
如：python manage.py makemigrations myblog myblog是我项目中的app名字
4、python manage.py migrate # 执行迁移，创建medel表结构
第五步：开始写代码吧
首先说下需求，就是在代码里向MySQL中插入一条记录并显示到页面
1、在templates下新建一个模板，其实就是页面，如index.html
<!DOCTYPE html><html lang="en"><head> <meta charset="UTF-8"> <title>Title</title></head><body><h2> {{article.title}}</h2>内容:{{ article.content }}</body></html>2、配置URL
1、在项目下的urls.py（注意是项目下的urls.py）配置url映射：
from django.conf.urls import url,includefrom django.contrib import admin#根url配置urlpatterns = [ #url(页面正则,响应的方法名称) url(r'^admin/', admin.site.urls), url(r'^myblog/',include('myblog.urls')),]include（'myblog.urls'）是我们接下来要配置的二级url,在app下的urls.py中配置from django.conf.urls import urlfrom django.contrib import adminfrom . import viewsurlpatterns = [ #url(页面正则,响应的方法名称) ^index$:表示要以index开始和结束，正则约束 url(r'^index/$',views.index),]3、写响应函数:如像数据中插入一个数据，并显示在页面上
我这里使用的pycharm，点击运行按钮即可，没有pycharm的可使用：
提交表单例子：
newarticle.html in testapp/templates 文件夹
1 <html>
2 <head>
3 <meta charset = "UTF-8">
4 <title>新添加一篇文章</title>
5 </head>
6 <body>
7 <form method="POST">
8 {% csrf_token %}
9 标题：<input type="text" name="articletitle" value="" /><br/>
10 作者：<input type="text" name="author" value="" /><br/>
11 文章内容：<textarea name="content" clos="100" rows="10" wrap="true"></textarea><br/>
12 <input type="submit" value="提交" />
13 </form>
14 </body>
15 </html>
testapp/views.py:
1 #__*__ encoding:UTF-8 __*__
2 from django.shortcuts import render
3 from django.http import HttpResponse
4 from testapp.models import Article
5
6 # Create your views here.
12
13 def newarticle(request):
14 if request.method == "GET":
15 return render(request,'newarticle.html')
16 if request.method == "POST":
17 print(request)
18 articletitle = request.POST.get('articletitle')
19 content = request.POST.get('content')
20 author = request.POST.get('author')
21 article = Article(title=articletitle,content=content,author=author)
22 article.save()
23 return render(request,'index.html',{'article':article})
urls.py in testapp:
from django.conf.urls import url
2 from django.contrib import admin
3 from . import views
4 urlpatterns = [
5 url(r'^index/$',views.index),
6 url(r'^newarticle/$',views.newarticle),
7 ]
urls.py under testdj/ folder：
from django.conf.urls import url,include
from django.contrib import admin
urlpatterns = [
url(r'^admin/', admin.site.urls),
url(r'^testapp/',include('testapp.urls')),
]
settings.py under testdj/ folder:
set ALLOWED_HOSTS with '*' for all ipaddresses and hostname, or set it with a special ipddress or hostname
ALLOWED_HOSTS = ['*']
or
ALLOWED_HOSTS = ['www.abyee.com']
For deploy on apache server:
also need to edit the wsgi.py file under project folder:
here is /usr/lib/djangotest/testdj/testdj/wsgi.py
code:
import os
from os.path import dirname,abspath
import sys
from django.core.wsgi import get_wsgi_application
project_dir = dirname(dirname(abspath(__file__)))
sys.path.insert(0,project_dir)
os.environ.setdefault("DJANGO_SETTINGS_MODULE", "testdj.settings")
application = get_wsgi_application()
