FIle upload with chunks: avoid saving it twice - django

Question

I use a custom function to upload a file splitting it in chunks, as documented here.
My problem is that calling save() after handle_uploaded_file() uploads my file twice, one into "MEDIA_URL/my_path" dir and one into "MEDIA_URL".
But I would like to have only one upload, the one with chunks.
It is possible to force save() to make 'chunked' upload?
Or should I use different approaches?
Thank you.
models.py
class ShapeFile(models.Model):
name = models.CharField(max_length=100)
srid = models.ForeignKey(SpatialRefSys)
user = models.ForeignKey(User)
color_table = models.ForeignKey(ColorTable)
file = models.FileField(upload_to="my_path")
class Meta:
unique_together = ('name', 'user')
forms.py
class UploadForm(ModelForm):
class Meta:
model = ShapeFile
fields = ('name','user','srid','file','color_table')
widgets = {'srid': TextInput(),
'user': HiddenInput()
views.py
def handle_uploaded_file(fileName, filePath):
with open(filePath, 'wb+') as destination:
for chunk in fileName.chunks():
destination.write(chunk)
#login_required
def shapeIng(request):
if request.method == 'POST':
form = UploadForm(request.POST, request.FILES)
if form.is_valid():
req = request.POST
# Split uploaded file into chunks
fileName = request.FILES['file']
filePath = ShapeFile(file=fileName).file.path
handle_uploaded_file(fileName, filePath)
form.save()
messages.success(request, 'Shapefile upload succesful!')
return redirect('shapeCreated')
else:
messages.error(request, 'Something went wrong uploading Shapefile.')
else: # request.method == 'GET'
form = UploadForm(initial={'user': request.user})
return render_to_response('my_app/base_shapeIngestion.html',
{'form': form},
context_instance=RequestContext(request))

change your view function to this:
def testupload2(request):
if request.method == 'POST':
file_name=request.FILES['file']
form = SomeForm(request.POST, request.FILES)
if form.is_valid():
dest_file = open('C:/prototype/upload/'+ str(file_name), 'wb+')
path = 'C:/prototype/upload/'+ str(file_name)
for chunk in request.FILES['file'].chunks():
dest_file.write(chunk)
dest_file.close()
t = get_template("testupload2.html")
lst = os.listdir('C:/downloads/prototype/prototype/upload/')
html = t.render(Context({'MEDIA_URL':'http://127.0.0.1:8000/site_media/'}))
return HttpResponse(html)
