一、生成Django框架

我这里使用的是PyCharm 2021.3.3

创建流程：

打开PyCharm
点击左上角File
选择New Project
选择Django
最后点击Create
然后在Django项目中添加一个文件夹，以便用来保存html文件

二、项目代码（前端）

1、编写前端代码（正文界面）

1.1、生产html框架

使用Visual Studio Code打开你刚刚在django项目创建的用来编写html文件的文件夹

首先创建一个index.html文件

英文感叹号加回车键生成html框架

1.2、添加live preview扩展

Live Preview 扩展的作用是在VSCode内部实现边写边预览的效果。

这个扩展主要用于HTML文件，它允许开发者在编写代码的同时实时查看代码渲染的效果，而不需要离开编辑器或打开浏览器。具体来说，Live Preview 扩展提供了以下几个便利的功能：

实时预览：当你在编辑HTML文件时，任何对代码的更改都会立即反映在预览窗口中，这样你可以即时看到改动效果，提高开发效率。

高度集成：作为微软官方插件，Live Preview与VSCode的集成程度非常高，使用起来非常流畅和方便。

简化操作：相比于其他如LiveServer等插件，Live Preview无需额外的保存和重启服务步骤，减少了繁琐的操作流程。

易于安装：你可以通过VSCode的扩展商店直接搜索并安装Live Preview，安装过程简单快捷。

自定义布局：你可以根据自己的需要调整预览窗口的位置，选择向上/下/左/右拆分，以适应不同的工作流程和屏幕布局。

直接安装即可

右键点击index.html文件，然后选择显示预览

1.3、更改title元素中文本

更改第六行的title元素

<title>AI 博客</title>

然后ctrl + s保存

1.4、添加CDN（CSS）样式链接

在第七行添加css的链接

<link href="https://cdn.jsdelivr.net/npm/tailwindcss@2.2.19/dist/tailwind.min.css" rel="stylesheet">

1.5、nav标签

从第十一行开始为nav标签


    <nav >
        
    </nav>

在第一个nav标签中添加一个类


    <nav class="bg-blue-600 p-4 text-white flex justify-between">

    </nav>

在nav标签中添加div标签

<div>

            <h1 class="text-3xl font-bold">AI 博客生成器</h1>

        </div>
        <div>
            <a href="#" class="text-white hover:underline">注销</a>

        </div>

1.6、在body标签中添加类

<body class="flex flex-col min-h-scrren bg-gray-100 font-sans antialised">

1.7、nav下创建div标签

创建h2标签之前先要创建三对div标签，三十八行到四十五行

   <div>
        <div>
            <div>
                <h2>欢迎来到AI博客生成器</h2>
            </div>
        </div>
    </div>

在最后一对div标签中创建h2和p标签

   <div>
        <div>

            <div class="text-center">

                <h2 class="text-2xl font-semibold mb-4">欢迎来到AI博客生成器</h2>

                <p class="text-gray-700">

                    使用人工智能从YouTube视频中生成高质量的博客文章。
                    只需输入链接到下面的YouTube视频，让人工智能为你创建内容!
                </p>
            </div>
        </div>

为前面两对div添加元素

   <div class="flex-grow container mx-auto mt-10 px-4 sm:px-0">


        <div class="max-w-3xl mx-auto bg-white p-6 rounded-lg">



            <div class="text-center">


                <h2 class="text-2xl font-semibold mb-4">欢迎来到AI博客生成器</h2>


                <p class="text-gray-700">

                    
                    使用人工智能从YouTube视频中生成高质量的博客文章。
                    只需输入链接到下面的YouTube视频，让人工智能为你创建内容!
                </p>
            </div>
        </div>

1.8、当前界面预览

在这里插入图片描述
在第二对div标签中添加内容

    <div class="flex-grow container mx-auto mt-10 px-4 sm:px-0">
        <div class="max-w-3xl mx-auto bg-white p-6 rounded-lg shadow-md transition-transform transform hover:scale-105 flex flex-col">
            <div class="text-center">
                <h2 class="text-2xl font-semibold mb-4">欢迎来到AI博客生成器</h2>
                <p class="text-gray-700">
                    使用人工智能从YouTube视频中生成高质量的博客文章。
                    只需输入链接到下面的YouTube视频，让人工智能为你创建内容!
                </p>
            </div>

            <br>

            <div>
                <h2 class="text-xl mb-4 font-semibold">请输入YouTube视频链接</h2>
                <div class="flex space-x-4">
                    <input id="youtubeLink" type="url" placeholder="请输入YouTube链接..." class="flex-grow p-2 border border-blue-400 rounded-l-md ">
                    <button id="generateBlogButton" class="bg-blue-600 text-blue px-4 py-2 rounded-r-md hover:gb-blue-700 transition-colors">提交</button>
                </div>
            </div>
        </div>

    </div>

添加section标签

    <div class="flex-grow container mx-auto mt-10 px-4 sm:px-0">
        <div class="max-w-3xl mx-auto bg-white p-6 rounded-lg shadow-md transition-transform transform hover:scale-105 flex flex-col">
            <div class="text-center">
                <h2 class="text-2xl font-semibold mb-4">欢迎来到AI博客生成器</h2>
                <p class="text-gray-700">
                    使用人工智能从YouTube视频中生成高质量的博客文章。
                    只需输入链接到下面的YouTube视频，让人工智能为你创建内容!
                </p>
            </div>

            <br>

            <div>
                <h2 class="text-xl mb-4 font-semibold">请输入YouTube视频链接</h2>
                <div class="flex space-x-4">

5、编写前端代码（文章页面）

5.1、完整代码

<!DOCTYPE html>
<html lang="en">
<head>
    <meta charset="UTF-8">
    <meta name="viewport" content="width=device-width, initial-scale=1.0">
    <title>博客文章</title>
    <link href="https://cdn.jsdelivr.net/npm/tailwindcss@2.2.19/dist/tailwind.min.css" rel="stylesheet">
</head>
<body class="bg-gray-100 font-sans antialiased">
    <nav class="bg-blue-600 p-4 text-white flex justify-between">
        <div>
            <h1 class="text-3xl font-bold">AI 博客生成器</h1>
        </div>
        <div>
            <a href="#" class="text-white hover:underline">登录</a>
            <a href="#" class="text-white hover:underline">注册</a>
        </div>
    </nav>
    <div class="container mx-auto mt-10 px-4 sm:px-0">
        <div class="max-w-3xl mx-auto bg-white p-6 rounded-lg shadow-md">
            <section>
                <h2 class="text-xl mb-4 font-semibold">博客文章详情</h2>
                <div class="border border-gray-300 p-4 rounded-lg">
                    <h3 class="text-lg font-semibold">博客文章标题</h3>
                    <p class="text-gray-700">博客文章内容</p>
                    <hr class="my-4 border-gray-300">
                    <h4 class="text-lg font-semibold">YouTube标题</h4>
                    <p class="text-gray-700">YouTube视频标签</p>
                    <h4 class="text-lg font-semibold mt-4">YouTube链接</h4>
                    <a href="#" class="text-blue-600 hover:underline">https://www.youtube.com</a>
                </div>
            </section>
        </div>
    </div>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <br>
    <footer class="text-center p-4 text-black mt-6">
        <a href="https://www.youtube.com/codewithtomi">作者YouTube链接</a>
    </footer>
    
</body>
</html>

三、Django代码（后端）

1、添加app功能

ai_blog_app是生成django模版时随着django生成的
在这里插入图片描述

INSTALLED_APPS = [
    'django.contrib.admin',
    'django.contrib.auth',
    'django.contrib.contenttypes',
    'django.contrib.sessions',
    'django.contrib.messages',
    'django.contrib.staticfiles',
    'blog_generato'
]

然后将ai_blog_app中的urls.py复制到blog_generato中
在这里插入图片描述
在blog_generato下的urls.py中添加url

from  . import views
from django.urls import path

urlpatterns = [
    path('', views.index,name="index"),
]

2、blog_generato添加index视图（views.py）

首先在ai_blog_app的urls.py文件中添加url路径

from django.contrib import admin
from django.urls import path,include

urlpatterns = [
    path('admin/', admin.site.urls),
    path('',include('blog_generato.urls'))
]

创建一个templates文件夹用来存放html前端代码，然后在ai_blog_app的settings.py问价中添加BASE_DIR , ‘templates’

TEMPLATES = [
    {
        'BACKEND': 'django.template.backends.django.DjangoTemplates',
        'DIRS': [BASE_DIR , 'templates']
        ,
        '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',
            ],
        },
    },
]

3、添加数据库

首先连接mysql数据库
在这里插入图片描述

在这里插入图片描述
根据自己使用的数据库来选择

注意：记得pip instal pymysql来安装mysql，然后在ai_blog_app下的_init_.py中添加代码，且已经创建好了django中需要使用的mysql环境

import pymysql

pymysql.install_as_MySQLdb()

然后更改ai_blog_app下settings.py中的mysql配置

DATABASES = {
    'default': {
        'ENGINE': 'django.db.backends.mysql',
        'NAME': 'ai_blog_app',
        'USER': 'root',
        'PASSWORD': 'yuan3128..',
        'HOST': 'localhost',
        'PORT': '3306',
    }

最后进行数据库迁移

PS E:\ai_blog_app> python manage.py makemigrations
PS E:\ai_blog_app> python manage.py migrate

4、创建管理员用户

PS E:\ai_blog_app> python manage.py createsuperuser
Username (leave blank to use 'yuanl'): （用户名）
Email address: （邮箱）
Password: （密码）
Password (again):（再次输入密码）
Superuser created successfully.

然后运行django项目，在浏览器中输入http://127.0.0.1:8000/admin进入后台管理页面
在这里插入图片描述

4.1、后台中文化

在seetings.py文件中将配置项LANGUAGE_CODE的值设置为“zh-Hans” ，TIME_ZONE的值设置为"Asia/Shanghai"

在seetings.py文件中配置项MIDDLEWARE(中间件)中添加本地化中间件
“django.middleware.locale.LocaleMiddleware”

LANGUAGE_CODE = 'zh-Hans'

TIME_ZONE = 'UTC'

USE_I18N = True

USE_TZ = True

4.2、在blog_generato下的urls.py中添加url

urlpatterns = [
    path('', views.index,name="index"),
    path('login', views.login, name="login"),
    path('signup', views.signup, name="signup"),
    path('logout', views.logout, name="logout"),
]

4.3、将注册登录html页面添加到views中

from django.shortcuts import render

# Create your views here.
def index(request):
    return render(request,'index.html')

def user_login(request):
    return render(request,'login.html')

def user_signup(request):
    return render(request,'signup.html')

修改signup.html中的代码

 <div>
            <a href="login" class="text-white hover:underline">登录</a>
            <a href="signup" class="text-white hover:underline">注册</a>
        </div>

修改login.html中的代码

 <div>
            <a href="login" class="text-white hover:underline">登录</a>
            <a href="signup" class="text-white hover:underline">注册</a>
        </div>

5、获取ai转换

地址：https://www.assemblyai.com/

注意：assemblyai库和websockets版本在10.0到11.0之间（根据自己的版本进行安装）
在这里插入图片描述
修改ai_blog_app中settings.py文件，并创建一个media文件夹
