Error while try to make widget to the form in django

I get an error when I try to add a widget to the form.

The error:

File "C:Userslibsite-packagesdjangoformsfields.py", line 558, in __init__
super().__init__(**kwargs)
TypeError: __init__() got an unexpected keyword argument 'attrs'

The model

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)
    video_poster = models.ImageField(max_length=255, upload_to='post-videos')

The views

def VideosUploadView(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 redirect('login')
    
    try:
        account = Account.objects.get(username=request.user.username)
    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, "video/upload_videos.html", contex)

The form

class Video_form(forms.ModelForm):

class Meta:
    model = Video
    fields = ('title', 'description', 'video', 'video_poster')

    widgets = {
        'title': forms.TextInput(attrs={'class': 'form-control'}),
        'description': forms.TextInput(attrs={'class': 'form-control'}),
        'video': forms.FileField(widget=forms.FileInput(attrs={'class': 'form-control'})),
        'video_poster': forms.ImageField(attrs={'class': 'form-control'}),


    }

Answer

You must assign valid widget in the Video_form:

widgets = {
    'title': forms.TextInput(attrs={'class': 'form-control'}),
    'description': forms.TextInput(attrs={'class': 'form-control'}),
    'video': forms.FileInput(attrs={'class': 'form-control'}),
    'video_poster': forms.ClearableFileInput(attrs={'class': 'form-control'}),
}

forms.FileField and forms.ImageField are fields not widgets.
