Django — File Upload

Model with FileField

class Document(models.Model):
    title = models.CharField(max_length=100)
    file = models.FileField(upload_to='documents/%Y/%m/')
    uploaded_at = models.DateTimeField(auto_now_add=True)

Upload Form

class DocumentForm(forms.ModelForm):
    class Meta:
        model = Document
        fields = ['title', 'file']

View

def upload_file(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return redirect('document_list')
    else:
        form = DocumentForm()
    return render(request, 'upload.html', {'form': form})

Template

<form method="post" enctype="multipart/form-data">
    {% csrf_token %}
    {{ form.as_p }}
    <button type="submit">Upload</button>
</form>

File Access

# In template
<a href="{{ document.file.url }}">Download</a>
<img src="{{ document.image.url }}" alt="Image">

# In Python
document.file.name   # Filename
document.file.url    # Full URL
document.file.size   # File size

Multiple File Upload

class MultipleFileForm(forms.Form):
    files = forms.FileField(widget=forms.ClearableFileInput(attrs={'multiple': True}))
