Difficulty uploading a file to a FileField, form isn't valid - django

Question

Halo, i'm trying to upload a file using filefield. But i always failed. when statement form.errors.as_data() executed, the browser return 'tempfile'. I already trying to find solution from django documentation and some django references. But, still can't fix it. ;(
Here's my view.py
def dataprocessing(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
import pdb; pdb.set_trace()
newdoc = Document(docfile=request.FILES['myfile'])
newdoc.save()
#Redirect to the dataprocessing after POST
#return render(request, 'dataprocessing.html')
return HttpResponse("success")
else:
return HttpResponse(form.errors.as_data())
else:
import pdb; pdb.set_trace()
form = DocumentForm() #A empty, unbound form
return render(request, 'dataprocessing.html', {'form': form})
models.py
class Document(models.Model):
docfile = models.FileField(upload_to='documents/%Y/%m/%d')
forms.py
class DocumentForm(forms.Form):
tempfile = forms.FileField()
And dataprocessing.html
<form method="post" enctype="multipart/form-data" action="{% url "dataprocessing" %}">
<div class="form-group">
<label for="up">Input Data</label> {% csrf_token %}
<input type="file" name=myfile class="filestyle" data-buttonName="btn-primary" data-buttonBefore="true" data-size="sm" accept="application/vnd.ms-excel, application/vnd.openxmlformats-officedocument.spreadsheetml.sheet"
id="up">
</div>
<div class="form-group">
<button type="submit" class="btn btn-primary btn-block">Upload Data</button>
<button type="button" class="btn btn-primary btn-block">Download Template</button>
</div>
</form>

How about using forms.ModelForm instaed forms.Form like this?
# forms.py
class DocumentForm(forms.Model):
class Meta:
model = Document
fields = ['tempfile']
and make your views.py like this:
# views.py
def dataprocessing(request):
if request.method == 'POST':
form = DocumentForm(request.POST, request.FILES)
if form.is_valid():
form.save()
return HttpResponse("success")
else:
return HttpResponse(form.errors.as_data())
else:
form = DocumentForm() #A empty, unbound form
return render(request, 'dataprocessing.html', {'form': form})
This makes form object can be saved directly to your model.
