django: Passing posted files through HttpResponseRedirect
I want to pass request.FILES from a post form to a different form through HttpResponseRedirect, I tried with session variables but I cannot pass a file through them. Is it possible ? if not: How can I do it?.
The reason I want to pass an XML file is because I will need to show the file's processed data in the next view that I am redirecting to with HttpResponseRedirect. Here is a snippet:
# View that handles post data
dev my_view(request):
if request.method == "POST":
form = myForm(request.POST, request.FILES)
my_file = request.FILES['xml']
if form.is_valid():
# Magic for passing files to the next view
# I tried with session variables, but I couldn't pass
# the file, as it couldn't be serialized.
return HttpResponseRedirect(reverse('form2'))
dev my_view2(request):
pass
# Here I'd receive the data from the previous form
# and handle it according to my needs.
Thanks in advance.
You cannot keep the posted files on HTTP redirect - it's how HTTP works.
If the redirect is not an absolute necessity, you can directly call the second view function from the first one:
# View that handles post data
dev my_view(request):
if request.method == "POST":
form = myForm(request.POST, request.FILES)
my_file = request.FILES['xml']
if form.is_valid():
# Magic for passing files to the next view
# I tried with session variables, but I couldn't pass
# the file, as it couldn't be serialized.
return my_view2(request) # <<<<<<< directly call the second view
dev my_view2(request):
pass
# Here I'd receive the data from the previous form
# and handle it according to my needs.
