How to solve Django file upload error?

Question

Django

Error: ValueError at /music/upload/
The Files could not be created because the data didn't validate.
I don't understand why
Model:

class Files(models.Model):
    user = models.ForeignKey(User)
    text = models.CharField(max_length=100)
    artist = models.CharField(max_length=50)
    our_file = models.FileField(upload_to='profile_image')
    image = models.ImageField(upload_to='profile_image', blank=True, default='new.jpg')
    data_time = models.DateTimeField(auto_now_add=True)

    def __str__(self):
        return self.text

The form:

class UploadForm(forms.ModelForm):
    text = forms.CharField(widget=forms.TextInput(
        attrs={
            'class': 'form-control',
            'placeholder': 'Введите название песни...'
        }
    ))

    artist = forms.CharField(widget=forms.TextInput(
        attrs={
            'class': 'form-control',
            'placeholder': 'Введите имя исполнителя...'
        }
    ))

    class Meta:
        model = Files
        fields = (
            'text',
            'artist',
            'our_file',
            'image',
        )

In template:

<form action="" method="post">
                {% csrf_token %}
                {{form.text}}
                <br>
                {{form.artist}}
                <hr>
                {{form.our_file}}
                <br>
                {{form.image}}
                <button type="submit" class="btn btn-success btn-lg">Подтвердить</button>
            </form>

In view:

class Upload(TemplateView):
    template_name = 'home/upload.html'

    def get(self, request):
        form = UploadForm()
        args = {
            'form': form
        }
        return render(request, self.template_name, args)

    def post(self, request):
        form = UploadForm(request.POST)
        if form.is_valid():
            new = form.save(commit=False)
            new.user = request.user
            new.save()

            return redirect('music:home')

        return redirect('music:home')
