I currently have a SessionWizardView from formtools package implemented.

class DataframeFormView(SessionWizardView):

    def done(self,form_list):

       params={}

        for form in form_list:

            params.update(form.cleaned_data)

        return HttpResponseRedirect(reverse('download',kwargs={'params':params}))

Everything is working fine in the forms view, and when the forms are successfully filled the above mentioned function runs, however I need to pass the params argument to another view:

from django_downloadview import VirtualDownloadView, VirtualFile

class DataframeDownloadView(VirtualDownloadView):

    def get_file(self):

         ### Access params dictionary here!!!!



        return VirtualFile(tfile.name, name=tfile.name)

Thing I've tried:

1) override __init__ to add self.params = kwargs.pop('params')

2) create method to access to kwargs specific key params using return self.kwargs['params']

3) Mixin solution (probably badly implemented but I thing there are constraints in these two CBVs)

Ultimately, suing method 1 and 2, I manage to access merely to a string representation of the params dictionary through reversing to download/url/. I need a more programatically solution to obtain the original dict object. TLDR: How can I pass complex objects between views.

Best regards,

As suggested by kungphu, probably the best way to share complex objects between views is using the view session.
For future reference, I end up doing the following:

def done(self,form_list,**kwargs):

    params={}

    for form in form_list:

        params.update(form.cleaned_data)

    self.request.session['params']=params

    return HttpResponseRedirect(reverse(self.download_url_name))

and I also changed the session serializer to pickle.
