Django Class Based Views Download Video YouTube return 404 not found in File

Using Django Mystery Errors
1

I’m developing a website for training in Django (Class Based View) that downloads a video that the user informs the URL on the front end. However, when returning the exact URL, Django appears as 404 - Not Found. How can I pass the parameter to download the file?

In urls.py I already inserted + static (settings.MEDIA_URL, document_root = settings.MEDIA_ROOT) to download the static files

Below are the files:

views.py

class PaginaPrincipal(TemplateView):
template_name = 'home/index.html'

def get(self, request, *args, **kwargs):
    if not os.path.exists('media/'):
        os.makedirs('media', exist_ok=True)
    for file in glob.glob('media/*.mp4'):
        if file:
            os.remove(file)
    return render(self.request, self.template_name)

def post(self, request):
    link = str(self.request.POST.get('link-youtube'))
    if link:
        func.videoDownload(link)
        return redirect(reverse_lazy('pagina-resultado'))
    return render(request, 'error.html', {'error': 'erro ao baixar, tente novamente'})

class PaginaResultado(TemplateView):
  template_name = 'home/result.html'

def get_context_data(self, **kwargs):
    context = super(PaginaResultado, self).get_context_data(**kwargs)
    arquivo = None
    for file in glob.glob('media/*.mp4'):
        arquivo = file
    context['videoDownload'] = arquivo
    return context

func.py

def videoDownload(url):
yt = YouTube(url)
yt.streams.order_by('resolution')[-1].download()
movingFileToCorrectPath(flag='video')
yt.streams.filter(only_audio=True)[-1].download()
movingFileToCorrectPath(flag='audio')
joinFile()
title = yt.title
urlVideo = 'https://www.youtube.com/watch?v=' + yt.video_id
views = yt.views
thumbnail = yt.thumbnail_url
author = yt.author
renameLastFile(title=title)
# print(title, urlVideo, views, thumbnail, author)



def movingFileToCorrectPath(flag):
if not os.path.exists('/static/video'):
    os.makedirs('static/video', exist_ok=True)

try:
    if flag == 'video':
        for file in glob.glob('*.webm'):
            os.renames(file, f'video-{file}')
            a = f'video-{file}'
        shutil.move(a, 'static/video/')
    elif flag == 'audio':
        for file in glob.glob('*.webm'):
            os.renames(file, f'audio-{file}')
            a = f'audio-{file}'
        shutil.move(a, 'static/video/')
    return
except Exception as e:
    print(e)


def joinFile():
arquivos = []
for file in glob.glob('static/video/*.webm'):
    arquivos.append(file)
arquivo1 = arquivos[0]
arquivo2 = arquivos[1]
joinFile = f'ffmpeg -i "{arquivo1}" -i "{arquivo2}" -c:v copy -c:a aac static/video/videofull.mp4'
os.system(joinFile)
for file in glob.glob('static/video/*.webm'):
    os.remove(file)
return

def renameLastFile(title):
for x in glob.glob('static/video/*.mp4'):
    os.renames(x, f'media/{title.replace(" ", "")}.mp4')
