load_data.py

def parse(file, username):     import csv     datareader = csv.reader(open(file), delimiter=',', quotechar='"')

# in forms.py... django import forms  class uploadform(forms.form):     csvfile = forms.filefield(         label='select csv file',     )

i'm not sure how pass in correct file type. if enter filepath manually load_data.py works fine, it's way it's passed in.

i think problem trying open wrong filename. when file uploaded webserver, either stored in memory, or written temporary location - django (https://docs.djangoproject.com/en/1.7/topics/http/file-uploads/#where-uploaded-data-is-stored).

so value in request.files['csv'] location of temporary file. want file gets stored in forms. need paste forms , models, guessing following might work, instead of

newdoc = csv(file=request.files['csvfile']) 

you need

newdoc = csv(file=form.cleaned_data['csvfile'])
