I implemented a form wizard to import bookmarks from various website
or
from a file: the first form selects the type of the import and, in
case I
want to import from a BibTeX file, the second form is a FileField
where I
have to indicate the path of the file containing the reference to
parse.
In this last case, after submit the file, reappears the last form with
the
error "This field is required." and I don't understand why.
Anyone has hints about this? below the drive-me-crazy code

# forms.py
class ImportFormWizard(FormWizard):
def process_step(self, request, form, step):
if step == 0:
if form.cleaned_data['import_type'] ==
'connotea':
self.form_list[1] = ImportConnoteaForm
elif form.cleaned_data['import_type'] ==
'bibtex':
self.form_list[1] = ImportBibtexForm
def done(self, request, form_list):
form, papers = handle_import(form_list)
return render_to_response(
'article/import.html',
{ 'form': form, 'articles': papers },
context_instance=RequestContext
(request)
)
class ImportMethodForm(Form):
IMPORT_TYPE = (
('connotea','Connotea'),
('bibtex','BibTeX'),
)
import_type = ChoiceField(choices=IMPORT_TYPE)
class ImportConnoteaForm(Form):
username = CharField()
password = CharField(widget=PasswordInput(render_value=False))
class ImportBibtexForm(Form):
bibtex_file = FileField()
