Jirka & Everybody
Back to basics is always a good advice. With your help and this guy:
http://www.beardygeek.com/2010/03/adding-views-to-the-django-admin/
I can create a form to upload csv files and input their records into
the database.
Short history:
Forms.py:
class DataInput(forms.Form):
file = forms.FileField()
place = forms.ModelChoiceField(queryset=Place.objects.all())
def save(self):
records = csv.reader(self.cleaned_data["file"])
for line in records:
input_data = Data()
input_data.place = self.cleaned_data["place"]
input_data.time = datetime.strptime(line[1], "%m/%d/%y %H:
%M:%S")
input_data.data_1 = line[2]
input_data.data_2 = line[3]
input_data.data_3 = line[4]
This form was imported in a view:
@staff_member_required
def import(request):
if request.method == "POST":
form = DataInput(request.POST, request.FILES)
if form.is_valid():
form.save()
success = True
context = {"form": form, "success": success}
return render_to_response("imported.html", context,
context_instance=RequestContext(request))
else:
form = DataInput()
contexto = {"form": form}
return render_to_response("imported.html", context,
context_instance=RequestContext(request))
And add the url pattern & some little changes to the admin index
template, and everything works the way i want.
Thanks guys!
