(2)Django-pycharm部署

pycharm

1.新建一个Django工程

2.部署

在pycharm下方的terminal终端中输入命令：

python manage.py startapp app1

生成“app1”文件夹

3.再部署

mysite下创建一个static的文件夹用来存放js,css,image等。templates用来存放.html文件

4.网页输出简单字符

views+urls

views代码

from django.shortcuts import render

from django.shortcuts import HttpResponse

# Create your views here.

def index(request):

    return HttpResponse("hello world")

urls代码

from django.conf.urls import url

from django.contrib import admin

from app1 import views

urlpatterns = [

    url(r'^admin/', admin.site.urls),

    url(r'^index/', views.index),

运行pycharm

访问http://127.0.0.1:8000/index/

5.引入html文件

views+urls+templates

在templates里增加一个html文件

起名index.html

<!DOCTYPE html>

<html lang="en">

<head>

    <meta charset="UTF-8">

    <title>meng</title>

</head>

<body>

<h1>123</h1>

</body>

</html>

urls代码

from django.shortcuts import render

from django.shortcuts import HttpResponse

# Create your views here.

def index(request):

    return render(request,"index.html",)

运行

6.引入静态文件

.views+urls+templates+static

为了引入js，对settings进行配置

STATIC_URL = '/static/'#自动生成了

STATICFILES_DIRS=(

    os.path.join(BASE_DIR,'static'),

)

index.html

<!doctype html>

<html>

<head>

<meta charset="utf-8">

<title>meng</title>

    <link rel="stylesheet" type="text/css" href="/static/css/mystyle.css">

</head>

<body>

<form action="/index/" method="post">

  <p>

    <label>账号:</label>

    <input type="text" name="username">

  </p>

  <p>

    <label>密码:</label>

    <input type="password" name="password">

  </p>

  <p>

    <input type="submit" value="提交">

    <input type="reset"  value="重置">

  </p>

</form>

</body>

</html>

views.py文件

from django.shortcuts import render

from django.shortcuts import HttpResponse

# Create your views here.

def index(request):

    if request.method == "POST":

        username = request.POST.get("username",None)

        password = request.POST.get("password",None)

        print(username,password)

    return render(request,"index.html",)

注释跨站请求保护机制

settings.py

MIDDLEWARE = [

    'django.middleware.security.SecurityMiddleware',

    'django.contrib.sessions.middleware.SessionMiddleware',

    'django.middleware.common.CommonMiddleware',

    #'django.middleware.csrf.CsrfViewMiddleware',# 注释

    'django.contrib.auth.middleware.AuthenticationMiddleware',

    'django.contrib.messages.middleware.MessageMiddleware',

    'django.middleware.clickjacking.XFrameOptionsMiddleware',

]

登陆index 输入账号密码，在服务器后台便打印出来

7.返回用户信息

views.py改成

from django.shortcuts import render

from django.shortcuts import HttpResponse

# Create your views here.

userlist=[

    {"user":"tom","pwd":""},

]

def index(request):

    if request.method == "POST":

        username = request.POST.get("username",None)

        password = request.POST.get("password",None)

        print(username,password)

        temp={"user":username,"pwd":password}

        userlist.append(temp)

    return render(request,"index.html",{"data":userlist})

index.html改成

<!doctype html>

<html>

<head>

<meta charset="utf-8">

<title>meng</title>

    <link rel="stylesheet" type="text/css" href="/static/css/mystyle.css">

</head>

<body>

<form action="/index/" method="post">

  <p>

    <label>账号:</label>

    <input type="text" name="username">

  </p>

  <p>

    <label>密码:</label>

    <input type="password" name="password">

  </p>

  <p>

    <input type="submit" value="提交">

    <input type="reset"  value="重置">

  </p>

</form>

{% for a in data %}

<p>{{ a.user }},{{ a.pwd }}</p>

{% endfor %}

</table>

</body>

</html>

8.数据库交互

配置settings

INSTALLED_APPS = [

    'django.contrib.admin',

    'django.contrib.auth',

    'django.contrib.contenttypes',

    'django.contrib.sessions',

    'django.contrib.messages',

    'django.contrib.staticfiles',

    'app1'#新增

]

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.sqlite3',

        'NAME': os.path.join(BASE_DIR, 'db.sqlite3'),#用此数据库默认有此代码

    }

}

编辑models.py

from django.db import models

# Create your models here.

class UserInfo(models.Model):

    user = models.CharField(max_length=32)

    pwd = models.CharField(max_length=32)

创建sqlite3的表

pycharm的teminal中通过命令创建数据库的表

python manage.py makemigrations

python manage.py migrate

....

修改views.py

from django.shortcuts import render

from django.shortcuts import HttpResponse

from app1 import models

# Create your views here.

def index(request):

    if request.method == "POST":

        username = request.POST.get("username",None)

        password = request.POST.get("password",None)

        #添加数据到数据库

        models.UserInfo.objects.create(user=username,pwd=password)

        #从数据库中读取所有数据

        userlist=models.UserInfo.objects.all()

    return render(request,"index.html",{"data":userlist})

view.py

from django.shortcuts import render

from django.shortcuts import HttpResponse

from app1 import models

# Create your views here.

def index(request):

    if request.method == "POST":

        username = request.POST.get("username",None)

        password = request.POST.get("password",None)

        #添加数据到数据库

        models.UserInfo.objects.create(user=username,pwd=password)

        #从数据库中读取所有数据

    userlist = models.UserInfo.objects.all()

    return render(request,"index.html",{"data":userlist})

登陆界面输入账号密码，

9、连mysql数据库

pycharm 里 file-Settings-

在pycharm里下载mysqlclient..

安装

settings.py 设置

DATABASES = {

    'default': {

        'ENGINE': 'django.db.backends.mysql',  #数据库驱动

        'NAME': 'mydatabase',  #数据库名

        'USER': 'mydatabaseuser',  #用户名

        'PASSWORD': 'mypassword',  #密码

        'HOST': '127.0.0.1',

        'PORT': '',

    }

}
