【问题描述】：

这里的代码运行良好，但我想显示多个视频。这里只显示一个视频。上传第二个视频时，第二个视频文件正在存储但不显示。请帮我解决这个问题。请。

views.py：

def showvideo(request):
    lastvideo= Video.objects.all()
    form= VideoForm(request.POST or None, request.FILES or None)
    if form.is_valid():
        form.save()
    context= {'lastvideo': lastvideo,
              'form': form
              }
    return render(request, 'master/video.html', context)

forms.py：

 class VideoForm(forms.ModelForm):
        class Meta:
            model= Video
            fields= ["name", "videofile"]

models.py：

 class Video(models.Model):
        name= models.CharField(max_length=500)
        videofile= models.FileField(upload_to='videos/', null=True, verbose_name="")
    
        def __str__(self):
            return self.name + ": " + str(self.videofile)

video.html：

 <html>
    <head>
    <meta charset="UTF-8">
    <title>Upload Videos</title>
    </head>
    <body>
    
    <h1>Video Uploader</h1>
    <form enctype="multipart/form-data" method="post" action="">
    {% csrf_token %}
    {{ form.as_p }}
    <input type="submit" value="Upload"/>
    </form>
    
    <br><br>
    <video width='400' controls>
    <source src='{{videofile.url}}' type='video/mp4'>
    Your browser does not support the video tag.
    </video>
    <br><br>
    </p>
    
    </body>
    <script>'undefined'=== typeof _trfq || (window._trfq = []);'undefined'=== typeof _trfd && (window._trfd=[]),_trfd.push({'tccl.baseHost':'secureserver.net'}),_trfd.push({'ap':'cpbh-mt'},{'server':'p3plmcpnl487010'},{'id':'8437534'}) // Monitoring performance to make your website faster.

    <script src='https://img1.wsimg.com/tcc/tcc_l.combined.1.0.6.min.js'></script>
    </html>

urls.py:

path('videos/',views.showvideo,name='showvideo'),

【解决方案1】：

在您看来，您是在保存前调用查询视频，请将其更改为：

def showvideo(request):
    form= VideoForm(request.POST or None, request.FILES or None)
    if form.is_valid():
       form.save()
    
    context= {'lastvideo': Video.objects.all(),
          'form': form
          }
    return render(request, 'master/video.html', context)

【讨论】：

只显示一个最后上传的视频
查看视频文件的绝对路径是不同还是相同？
不一样
当我添加上面的代码时它没有查看

【解决方案2】：

这里，如果我们要显示多个视频，那么在这个模板中添加for循环

<html>
        <head>
        <meta charset="UTF-8">
        <title>Upload Videos</title>
        </head>
        <body>
        
        <h1>Video Uploader</h1>
        <form enctype="multipart/form-data" method="post" action="">
        {% csrf_token %}
        {{ form.as_p }}
        <input type="submit" value="Upload"/>
        </form>
        
        <br><br>
        {% for video in lastvideo %}
        <tr>
         <td>
            <video width='400' controls>
            <source src='{{video.videofile.url}}' type='video/mp4'>
             Your browser does not support the video tag.
             </video>
         </td>
         </tr>
        {% endfor %}
        <br><br>
        </p>
        
        </body>
        <script>'undefined'=== typeof _trfq || (window._trfq = []);'undefined'=== typeof _trfd && (window._trfd=[]),_trfd.push({'tccl.baseHost':'secureserver.net'}),_trfd.push({'ap':'cpbh-mt'},{'server':'p3plmcpnl487010'},{'id':'8437534'}) // Monitoring performance to make your website faster.

        </html>
