I am trying to use django SessionWizard view for the forms with 2 steps. ON first step I get file location and on second step process the file contents and write them to db on submit of second step. When I am clicking on submit, the form goes back to first step. I tested it using CookieWizardView and the form works fine with that - I am able to write data to db on submit of second step. For SessionWizardView, I verified that sessions are enabled in my application as per documentation here - Also verified that sessions table is in my db and is non-empty.
Have seen related questions, but not to much help.
Below is the code snippet of my view
class UploadWizard(SessionWizardView):
def __init__(self, *args, **kwargs):
super(UploadWizard, self).__init__(*args, **kwargs)
self.uploaded_file = None
self.ingestable_upload = None
self.error = None
form_list = UPLOAD_FORMS
# TODO: sweep for old files. Maybe move to S3?
upload_dir = os.path.join(settings.MEDIA_ROOT, 'uploads')
file_storage = FileSystemStorage(location=upload_dir)
def get_template_names(self):
return [TEMPLATES[self.steps.current]]
def get_form(self, step=None, data=None, files=None):
if step is None:
step = self.steps.current
form = super(UploadBoxofficeWizard, self).get_form(step, data, files)
if step == MAP_DATA_STEP:
# do something
return form
def process_step(self, form):
if self.steps.current == PICK_FILE_STEP:
action = form.cleaned_data.get('action')
extractor = get_upload_extractor_for_source(form.cleaned_data.get('source'))
uploaded_file = form.cleaned_data.get('file')
start_date = form.cleaned_data.get('start_date')
end_date = form.cleaned_data.get('end_date')
if action == INGEST_ACTION:
#do something
elif self.steps.current == MAP_DATA_STEP:
# do something
def done(self, form_list, form_dict, **kwargs):
form = form_list[int(MAP_DATA_STEP)]
num_rows= 0
if form:
num_rows = form.cleaned_data[0].get('num_rows')
return render_to_response('formtools/wizard/show_result.html',{'num_rows':num_rows})
Sessions setup
INSTALLED_APPS = (
'django.contrib.sessions',
)
MIDDLEWARE_CLASSES = [
'django.contrib.sessions.middleware.SessionMiddleware',
'django.contrib.auth.middleware.AuthenticationMiddleware',
'django.contrib.auth.middleware.RemoteUserMiddleware',
'django.contrib.messages.middleware.MessageMiddleware',
'django.middleware.clickjacking.XFrameOptionsMiddleware',
]
Looking for some help to get ideas on what might be going wrong here. I have followed the steps from documentation but clearly I am missing something.
