I used a different approach.
The form:
form = widgets.TableForm(fields = [
widgets.FileField(
name = 'image',
label = _('Some picture'),
validator = validators.FieldStorageUploadConverter())
])
Saving the image to the database:
@expose()
@validate(validators = {
'image': validators.FieldStorageUploadConverter()
})
def save(self, image):
image = model.Image(
fileName = image.filename,
image = image.file.read(),
)
return dict(image_id = image.id)
Retrieving the image from the database:
@turbogears.expose(content_type = "image/jpg")
def show_image(self, image_id):
# "model.Image.q.image is where the image is stored
return model.Image.get(image_id).image
Of course, if you need some pre-processing -- such as resizing, creating
thumbnails, etc. -- you need to "image.file.read()" before saving the image
to the database.
Thanks, Julio!
