Thanks,
if I understand it right, your suggestion means:
- create CPSImageWithThumbnailField(CPSImageField), with a
computeDependantFields method, that takes the original imagefield
data, uses PIL to create the thumbnail and write the new image to the
thumbnail field.
Yes, make the name (or better, suffix) of the dependent field
configurable through a property.
Check CPSFileField declaration (in CPSSchema/BasicFields.py)
- change my Photo schema, to one CPSImageWithThumbnailField and one
CPSImageField(?) or two CPSImageWithThumbnailFields
The first of these possiblities, where of course you name the
thumbnail field according to what you
configured in the main one
- what layout should i choose? since i still want to be able to use it
TTW: change my layout, so that instead of using a photo widget I use a
normal image widget and on each change of the image, the thumbnail
field is updated thru the computedependantfields method?
I'm don't remember that well what PhotoWiget does. Anyway, you can use
your field with any Image oriented widget.
- If i then use the remote controller or createFile it is sufficient
to provide the image file in the doc_def, because again,
computedependantFields would thumbnail...
Yes. More precisely, this happens at DataModel commit time.
Did I get that right? Thanks, Michael
Seems so, yes !

Hi
I think you'd want to use the computeDependantFields (sic) method of
fields. So instead of
subclassing the Image widget, you could subclass the CPS ImageField,
and have it take care of the
thumbnail. This should catch all these use cases. For example, I've
done this to read ID3 tags from MP3 files.
In mainstream CPS, this is used to apply transforms, like converting
pdf to text for indexing.
