1.创建模板

2.配置项目读取模板路径  
在DIRS 中添加 os.path.join(BASE\_DIR, ‘templates’)

使用pycharm创建项目的已经自动配置好的  
3.编写视图代码  
在应用视图中编写

from django.template import loader
    
    
    def index(request):
        tmp = loader.get_template('booktest/index.html')
        return HttpResponse(tmp.render())

5.利用render 方法给模板渲染返回值

from django.shortcuts import render
    from django.template import loader
    
    
    def index(request):
        context = {"hello":"world"}
    
        # tmp = loader.get_template('booktest/index.html')
        # return HttpResponse(tmp.render())
    
        return render(request,'booktest/index.html',context)

视图代码

from django.shortcuts import render
    
    from booktest.models import BookInfo
    
    
    def index(request):
        # context = {"hello": "world"}
        #
        # # tmp = loader.get_template('booktest/index.html')
        # # return HttpResponse(tmp.render())
        # return render(request, 'booktest/index.html', context)
    
        book1 = BookInfo(btitle="123", bpup_date=timezone.now())
        book2 = BookInfo(btitle="123", bpup_date=timezone.now())
        book3 = BookInfo(btitle="123", bpup_date=timezone.now())
    
        bookList = []
        bookList.append(book1)
        bookList.append(book2)
        bookList.append(book3)
        context = {"bookList": bookList}
        return render(request, 'booktest/index.html', context)

html 代码

<!DOCTYPE html>
    <html lang="en">
    <head>
        <meta charset="UTF-8">
        <title>Title</title>
    
    </head>
    <body>
    <h1>HELL0 WORLD</h1>
    <h2>{
       { hello }}</h2>
    
    <ul>
    {% for book in bookList %}
        <li>{
       { book.btitle }}</li>
    {%endfor%}
    </ul>
    </body>
    </html>
