Hello,
I have a model with a FileField.
When using the MyModel.AddManipulator() in the view, everything works
as expected.
But I need a custom manipulator. I've already made some custom
manipulators that works pretty well, so I'm sure I'm not too wrong
here. The one that don"t works is the one that need to save an
uploaded file.
Here it is:
class CsvDataManipulator(forms.Manipulator):
def __init__(self, pk=None):
if pk:
self.original_object = CsvData.objects.get(id=pk)
self.pk = pk
else:
self.original_object = None
self.pk = None
self.fields = (
forms.FileUploadField(field_name='csv_file', is_required=False),
forms.TextField(field_name='csv_sep', is_required=True,
maxlength=1),
)
def save(self, new_data):
if self.original_object:
temp = dict(
csv_file=new_data['csv_file'],
csv_sep=new_data['csv_sep']
)
for k,v in temp.iteritems():
self.original_object.__setattr__(k, v)
self.original_object.save()
return CsvData.objects.get(id=pk)
else:
temp = CsvData(
csv_file=new_data['csv_file'],
csv_sep=new_data['csv_sep']
)
temp.save()
return temp
In the view, it's used like this:
...
manipulator = CsvDataManipulator()
new_data = request.POST.copy()
if request.FILES:
new_data.update(request.FILES)
errors = manipulator.get_validation_errors(new_data)
Then i have an error that show that new_data['csv_file'] hold the
content of the uploaded file:
Any help welcome.
Thanks
