I building a website using Django and I would like to create a functionality in which an user via an excel sheet can upload information and populate the database. So I install the django-excel package and follow the example:

**settings.py**:

```
FILE_UPLOAD_HANDLERS = ("django_excel.ExcelMemoryFileUploadHandler",
                    "django_excel.TemporaryExcelFileUploadHandler")

```

**urls.py**:

```
url(r'^import_sheet/', views.import_sheet, name="import_sheet"),

```

**views.py**:

```
class UploadFileForm(forms.Form):
   file = forms.FileField()

def upload(request):
if request.method == "POST":
    form = UploadFileForm(request.POST, request.FILES)
    if form.is_valid():
        filehandle = request.FILES['file']
        return excel._make_response(filehandle.get_sheet(),"xslx",file_name="download")  
    else:
        form = UploadFileForm()
        return render(request,'upload_form.html',{
            'form': form,
            'title': 'Excel file upload',
            'header': 'Please choose a valid excel file'
        })

def import_sheet(request):
    if request.method == "POST":
        form = UploadFileForm(request.POST,
                          request.FILES)
        if form.is_valid():
            request.FILES['file'].save_to_database(
                model= quote_input,
                mapdict= ["value_date", "value", "type", 'name'])
            return HttpResponse("OK")
        else:
            return HttpResponseBadRequest()
    else:
        form = UploadFileForm()
    return render(
        request,
        'upload_form.html',
        {'form': form})

```

**models.py**:

```
class quote_input(models.Model):
    value_date  = models.DateField()
    value       = models.FloatField()
    type        = models.TextField(max_length=254)
    name        = models.TextField(max_length=254)
    # link
    fund            = models.ForeignKey(Fund)
    benchmark       = models.ForeignKey(Benchmark)
    factor          = models.ForeignKey(Factors)
    stress_factor   = models.ForeignKey(Stress_Factors)

```

When I try this code by uploading a basic excel sheet:
[![enter image description here](https://i.stack.imgur.com/xEade.png)](https://i.stack.imgur.com/xEade.png)

I got an OK (HttpResponse) but when I looked at the database, I have uploaded nothing.

Does someone have the same problem? or can provide another example that I can use? another methodology? 

Another question: within the django-excel documentation, there is a reference about a function "choice\_func" which is defined as a custom formatting function. Can anyone provide more information about this function?
