Hi, having some trouble saving images to db.
The file:
self.DataStructure = (
('Id', 'I', True, 'Persona', 'Id'),
('Apellido', 'C', False, 'Persona', 'Apellido'),
('Nombre', 'C', False, 'Persona', 'Nombre'),
('DNI', ' I', False, 'Persona', 'DNI'),
('Domicilio', 'C', False, 'Persona', 'Domicilio'),
('Localidad', 'C', False, 'Persona', 'Localidad'),
('Foto', 'L', False, 'Persona', 'Foto'),
)
self.Encoding = 'utf-8'
As you can see I define Foto as a buffer ('L') field (not sure if that's
how it should be done).
The control:
foto = ImgBtn(self,
RegID='Foto',
DataSource='Persona',
DataField='Foto',
Size=(200, 200),
ScaleMode='Stretch',
DroppedFileHandler=self.Form)
Updating the image field:
picFile = dabo.ui.getFile('png', 'jpg', 'gif', 'bmp')
self.Foto.Value = open(picFile, "rb").read()
But when I issue self.Form.save() I get the following:

It would seem the problem is the encoding? Dabo is trying to decode the
image?
Don't know if I'm making some kind of mistake or if it's some bug, and I
don't know if this can be worked out.
But if someone has persisted images in a db I would appreciate any
workaround you can suggest.
Thanks
