I have model that represents a file, and has a FileField, that I am
rendering via an Inline Formset. When a user fills in the form it gets
saved with no problems.
However, I want the users to be able to continue editing the file, but
when I re-display the newly created object, the data for the FileField
doesn't show, so if the user edits some data but doesn't re-upload the
file, she gets an error.
How can I make the formset render the FileField's current value within
the form field?
Here's the view, the Parent model is "Articulo", the inline model is
"Archivo":
ArchivoInlineFormSet = inlineformset_factory(Articulo, Archivo,
extra=3)
@login_required
def create_article(request, id=False):
text = "Enviar"
button = "Enviar"
user = request.user
if request.method == 'POST':
#save data for new article
form = ArticuloForm(request.POST, request.FILES)
if form.is_valid():
#save info
articulo = form.save()
articulo.autores.add(user.get_profile())
articulo.save()
formset = ArchivoInlineFormSet(request.POST,
request.FILES, instance=articulo)
if formset.is_valid():
formset.save()
else:
#start editing new article
form = ArticuloForm()
formset = ArchivoInlineFormSet()
objContext = RequestContext(request, locals())
return render_to_response("editar/articulo.html", objContext)
and the class, the troublesome field is "archivo":
class Archivo(models.Model):
articulo = models.ForeignKey(Articulo)
tipo = models.IntegerField()
numero = models.IntegerField()
archivo = models.FileField(upload_to="archivos")
etapa = models.IntegerField()
