I have this:
db.define_table('uploads',
Field('name','string'),
Field('fileit','upload'),
Field('thumbnail','upload',),
)
This is my onvalidate function:
def WriteThumb(form):
import StringIO
i = StringIO.StringIO()
o = StringIO.StringIO()
i.write(form.vars.fileit.value)
i.seek(0)
im = Image.open(i, 'r')
im.thumbnail((100,100),Image.ANTIALIAS)
im.save(o,'JPEG')
o.seek(0)
form.vars.thumbnail = base64.b64encode(o.getvalue())
o.close()
i.close()
If I leave the input blank on Thumbnail I get this url saved:
http://127.0.0.1:8000/testapp/default/download//9j/4AAQSkZJRgABAQAAAQABAAD/2wBDAAgGBgcGBQgHBwcJCQgKDBQNDAsLDBkSEw8UHRofHh0aHBwgJC4nICIsIxwcKDcpLDAxNDQ0Hyc5PTgyPC4zNDL
If I do use a filename, which will be overwritten by the new
Thumbnail, I get this text url:
http://127.0.0.1:8000/gaeupload/default/download/uploads.thumbnail.832b5cf1989b3feb.66696c652e747874.txt
I tried StringIO and CStringIO, but no joy.
How do I get my function to put data into Thumbnail so that it save
properly in file system? Or, maybe someone would share a better
way...
Thanks, David
