Hello,
I have a edit view to modify an object. The model includes an inline
formset of insumoRecurso objects, for including files associated with the
main object. These files appear with a checkbox for clearing files
(ClearableFileInput widget). What should I test on my view to detect that
the checkbox has been selected?
Here's the code of my view:
@login_required
def editarRecurso(request, recurso_id):
recurso = get_object_or_404(Recurso, pk=recurso_id)
objetos = {}
objetos["recurso"] = recurso
u = request.user
if recurso.creador != u and not (usuarioEsSupervisor(u) or
usuarioEsCoordinador(u)):
objetos["mensaje_de_error"] = "Usted no puede editar este recurso."
else:
InsumoFormset = inlineformset_factory(Recurso, InsumoRecurso, extra=1)
if request.method == 'POST':
recursoForm = RecursoForm(request.POST, instance=recurso)
insumoFormset = InsumoFormset(request.POST, request.FILES, instance =
recurso)
if recursoForm.is_valid():
recurso = recursoForm.save(commit=False)
recurso.save()
notificarCreacionRecurso(request, recurso)
for insumoForm in insumoFormset:
if insumoForm.is_valid():
insumoRecurso = insumoForm.save(commit=False)
if not insumoRecurso.archivo.name: #This is the way I found for
not saving objects that doesn't have an uploaded file (i.e., when user
doesn't choose a file to upload)!!! is there a better way?
continue
ir = insumoRecurso.save()
if insumoRecurso.archivo.remove: #This is not working, "remove"
attribute doesn't exist... but here is where I expect a way of detecting
clear checkbox selection. If there is no file, then the whole insumoRecurso
object must be deleted.
ir.delete()
return redirect(reverse('recursos:detalle', args=(recurso.id,)))
else:
objetos["recursoForm"] = recursoForm
objetos["insumoFormset"] = insumoFormset
else:
objetos["recursoForm"] = RecursoForm(instance=recurso)
objetos["recursoForm"].fields["curso"].queryset =
Curso.objects.filter(owner=request.user)
objetos["insumoFormset"] = InsumoFormset(instance=recurso)
template = loader.get_template('recursos/editarRecurso.html')
context = RequestContext(request, objetos)
return HttpResponse(template.render(context))
I would appreciate any help, By the way, even though I check the clear
checkbox, the file is never deleted (I would assume that would happen on
insumoRecurso.save(), but the files always remain there)
Thanks,
Hector.
