J'ai un formulaire qui semble ne jamais valider. Le formulaire est juste trois listes déroulantes. Lorsque le formulaire est rendu, toutes les zones ont des valeurs remplies et la première est sélectionnée, donc quoi qu'il arrive, l'utilisateur ne peut pas soumettre de mauvaises valeurs, mais form.is_valid() retourne toujours false. S'il vous plaît aider!Problème de validation de formulaire Django
La forme
CLUSTER_TYPES = (
('ST', 'State'),
('CNT', 'County'),
('FCD', 'Congressional District'),
('GCC', 'Circle Clustering'),
);
MAP_VIEWS = (
('1', 'Single Map'),
('2', 'Two Maps'),
('4', 'Four Maps'),
);
class ViewDataForm (forms.Form):
def __init__ (self, sets = None, *args, **kwargs):
sets = kwargs.pop ('data_sets')
super (ViewDataForm, self).__init__ (*args, **kwargs)
processed_sets = []
for ds in sets:
processed_sets.append ((ds.id, ds.name))
self.fields['data_sets'] = forms.ChoiceField (label='Data Set', choices = processed_sets)
self.fields['clustering'] = forms.ChoiceField (label = 'Clustering',
choices = CLUSTER_TYPES)
self.fields['map_view'] = forms.ChoiceField (label = 'Map View', choices = MAP_VIEWS)
La vue
def main_view (request):
# We will get a list of the data sets for this user
sets = DataSet.objects.filter (owner = request.user)
# Create the GeoJSON string object to potentially populate
json = ''
# Get a default map view
mapView = MapView.objects.filter (state = 'Ohio', mapCount = 1)
mapView = mapView[0]
# Act based on the request type
if request.method == 'POST':
form = ViewDataForm (request.POST, request.FILES, data_sets = sets)
v = form.is_valid()
if form.is_valid():
# Get the data set
ds = DataSet.objects.filter (id = int (form.cleaned_data['data_set']))
ds = ds[0]
# Get the county data point classifications
qs_county = DataPointClassification.objects.filter (dataset = ds,
division = form.cleaned_data['clustering'])
# Build the GeoJSON object (a feature collection)
json = ''
json += '{"type": "FeatureCollection", "features": ['
index = 0
for county in qs_county:
if index > 0:
json += ','
json += '{"type": "feature", "geometry" : '
json += county.boundary.geom_poly.geojson
json += ', "properties": {"aggData": "' + str (county.aggData) + '"}'
json += '}'
index += 1
json += ']}'
mapView = MapView.objects.filter (state = 'Ohio', mapCount = 1)
mapView = mv[0]
else:
form = ViewDataForm (data_sets = sets)
# Render the response
c = RequestContext (request,
{
'form': form,
'mapView_longitude': mapView.centerLongitude,
'mapView_latitude': mapView.centerLatitude,
'mapView_zoomLevel': mapView.zoomLevel,
'geojson': json,
'valid_was_it': v
})
return render_to_response ('main.html', c)
Si j'avais été attentif, 'sets = None' n'aurait pas été là en premier lieu. Merci beaucoup. – Nik
