I built an app which allows the user to upload a file. On the other hand, I have some python script which takes a text file, convert it to CSV and do pandas. This script works perfectly when running in the terminal. Now I want to apply that python script to the file upload in Django and show that file in httpResponse and make available to download it.

python script

import csv
import pandas as pd

df = pd.read_csv('raw_df.txt', delimiter = '\t' , usecols=['Sample','Cohort','Metabolite Name','Intensity'])
df = df[df['Cohort'].str.contains("std")]
df = df.groupby(['Cohort', 'Metabolite Name'])['Intensity'].sum().reset_index()
df = df[['Cohort','Intensity']]
c = 'Cohort'
s = df.set_index([c, df.groupby(c).cumcount() + 2]).Intensity
df =    s.unstack().add_prefix('Intensity').reset_index()
df.to_csv()
print df;

views.py

    from django.shortcuts import render, redirect
from django.conf import settings
from django.core.files.storage import FileSystemStorage

from uploads.core.models import Document
from uploads.core.forms import DocumentForm


def home(request):
    documents = Document.objects.all()
    return render(request, 'core/home.html', { 'documents': documents })

def model_form_upload(request):
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            form.save()
            return redirect('home')
    else:
        form = DocumentForm()
    return render(request, 'core/model_form_upload.html', {
        'form': form
    })

Models.py

class Document(models.Model):
document = models.FileField(upload_to='documents/')

template-upload page
