未验证用户尝试观看视频时出现错误 我需要让未经身份验证的用户可以看到内容视频，但绝对不能发布任何视频

型号

class Video(models.Model):
author = models.ForeignKey(Account, on_delete=models.CASCADE)
video = models.FileField(upload_to='post-videos')
title = models.CharField(max_length=100)
description = models.TextField(null=True, blank=True)
allow_comments = models.BooleanField(default=False)
is_public = models.BooleanField(default=False)
created_date = models.DateTimeField(auto_now_add=True)
modified_date = models.DateTimeField(auto_now=True)
publish_date = models.DateTimeField(null=True, blank=True)

表格

class Video_form(forms.ModelForm):
class Meta:
    model = Video
    fields = ('title', 'description', 'video')

观点

def home_screen_view(request, *args, **kwargs):
all_videos = Video.objects.all()
V_form = Video_form()
video_added = False
account = Account.objects.get(username=request.user)
if 'submit_v_form' in request.POST:
    print(request.POST)
    V_form = Video_form(request.POST, request.FILES)
    if V_form.is_valid():
        instance = V_form.save(commit=False)
        instance.author = account
        instance.save()
        V_form = Video_form()
        video_added = True

contex = {
    'all_videos': all_videos,
    'account': account,
    'V_form': V_form,
    'video_added': video_added
}
return render(request, "personal/home.html", contex)

def home_screen_view(request, *args, **kwargs):
    all_videos = Video.objects.all()
    V_form = Video_form()
    video_added = False
    
    if not request.user.is_active:
        # any error you want
        return HttpResponse('Inactive User')
    
    try:
        account = Account.objects.get(username=request.user)
    except:
        # any error you want
        return HttpResponse('User does not exits.')
    
    if 'submit_v_form' in request.POST:
        print(request.POST)
        V_form = Video_form(request.POST, request.FILES)
        if V_form.is_valid():
            instance = V_form.save(commit=False)
            instance.author = account
            instance.save()
            V_form = Video_form()
            video_added = True
    
    contex = {
        'all_videos': all_videos,
        'account': account,
        'V_form': V_form,
        'video_added': video_added
    }
return render(request, "personal/home.html", contex)
