python使用jdango创建web项目完整步骤

一、首先我们使用pycharm创建一个jdango项目

app名称为jdango_Second,创建好的格式如图所示：


二、我们创建的项目是MTV模式的

即model(对应数据库),templates（页面显示）,view（逻辑处理）

          models.py:

from django.db import models

# Create your models here.
class Stu(models.Model):
    id = models.CharField(max_length=16,primary_key=True)
    name=models.CharField(default='dqd',max_length=16)

views.py:

from django.shortcuts import render
from jdango_Second.models import Stu
# Create your views here.
def showInfo(request):
    stu_list = Stu.objects.all()
    content = {'list':stu_list}
    return render(request,'index.html',content)

在admin.py将models.py中的类注册：

from django.contrib import admin
from jdango_Second.models import Stu
# Register your models here.
admin.site.register(Stu)

在项目的__init__.py我们可以做一些初始化（second）：

import pymysql
pymysql.install_as_MySQLdb()

db = pymysql.connect("localhost",'root','','py_second')

cursor = db.cursor()

cursor.execute('SELECT VERSION()')

data = cursor.fetchone()

print("Version is %s" % data)

db.close()

同样在项目的setting.py中我们设置链接的数据库和制定静态路径和templates的路径：

    'django.middleware.clickjacking.XFrameOptionsMiddleware',
]

ROOT_URLCONF = 'second.urls'

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [os.path.join(BASE_DIR, 'templates')]
        ,

WSGI_APPLICATION = 'second.wsgi.application'

# Static files (CSS, JavaScript, Images)

STATIC_URL = '/static/'

STATIC_PATH = os.path.join(BASE_DIR,'static')
STATICFILES_DIRS = (
    STATIC_PATH,
)

TEMPLATE_PATH = os.path.join(BASE_DIR,'templates')
TEMPLATE_DIRS=[
    TEMPLATE_PATH,
]

项目的urls.py中配置浏览器地址栏的路径和views.py中的函数名称对应起来：

from django.conf.urls import url
from django.contrib import admin
from jdango_Second.views import showInfo

urlpatterns = [
    url(r'^admin/',admin.site.urls),
    url(r'^index/',showInfo),
]

static路径下用于放置各种静态文件,如：

static

     img

          1.png

     js

     css

templates的路径为：

templates

      index.html

index.html:

<!DOCTYPE html>
{% load staticfiles %}
<html lang="en">
<head>
    <meta charset="UTF-8">
    <title>Title</title>
</head>
<body>

<image src="{% static 'img/1.jpg' %}"/>
<ul>
    {%for item in list%}
        <li>
            {{ item.id }}
            {{ item.name }}
        </li>
    {% endfor %}
</ul>
</body>
</html>


三、创建 Django admin 用户名和密码：


初始化数据库表

manage.py@HelloDj > makemigrations


manage.py@HelloDj > migrate


2.3 创建admin user

manage.py@HelloDj >createsuperuser



输入用户。。密码。。

(参考：http://blog.csdn.net/wengyupeng/article/details/52266635)



四、打开浏览器输入localhost:8000/admin进入如下界面：


点击Stus,进入增添数据即可，然后在在地址栏输入localhost:8000/index就可以看到数据库中取出的数据了
