Django - 如何通过重定向传递数据（参数？） function

Question

I have a django view where a user uploads a large file. I scrape a ton of information from this file and hold it in memory. I don't want to save this information to the database because it takes too long and I don't need to save it. But I want to continue to use this data in the next view. How do I send along this data using redirect?

def view_one(request):
     if request.method == 'GET':
          return render(request, 'view_one.html')
     if request.method == 'POST':
          uploaded_file = request.FILES['my_file']
          info, data = scrape_my_file_for_info_and_data(uploaded_file)
          return redirect('path_to_view_two', info, data)

def view_two(request, info, data):
     do_stuff_with_info(info)
     do_stuff_with_data(data)

I keep getting errors that I am missing positional arguments 'info' and 'data'. I've tried doing:

return redirect('path_to_view_two', info=info, data=data)
return redirect(view_two(info, data))

But this doesn't work either. I can't find an example online of how to properly do this and I can't make heads or tails out of the django documentation. Seems there should be an easy way to do this, I just haven't landed on it.

Thanks for reading my question!

According to docs you missed quotes in defining positional arguments

it should be like that:

return redirect('path_to_view_two', info='info', data='data')

Also you can consider saving data to user's session and retrieving on the redirected view - sessions docs

def view_one(request):
     data = scrape_my_file_for_info_and_data(uploaded_file)
     request.session['data'] = data

def view_two(request):
     data = request.session.get('data')
