how to upload and read csv file in django using csv.DictReader?

Question

I am reading csv file through upload and trying to store all values in a list

def upload(request):
    paramFile = request.FILES[\'file\'].read()
    data =          


        

Answer 1

You have two problems:

• You are passing a string to the constructor of DictReader. You must pass an iterable object that gives the individual lines in the input (a string is iterable, but will give each character one at a time). Luckily, an UploadedFile object (like those in the FILES dictionary) are already file-like objects that support iteration, so just do this:

  data = csv.DictReader(request.FILES['file'])
  

• Your input data only has one line. DictReader will use that line for the column "headers", which will become the key in the resulting dictionaries. You will then have no data left! It looks like you don't want a DictReader, just a regualar reader:

  data = csv.reader(request.FILES['file'])
