It took me a while to isolate the problem. Here is a simple code to
reproduce it:
def index():
db.define_table('thing',Field('image','upload',requires=IS_NOT_EMPTY()))
db.thing.image.default = 'xxx.png'
form = SQLFORM.factory(db.thing,upload=URL('download')).process()
return locals()
It is a bin can of worms and I opened a ticket about this. For now I will
just say that giving a default to an upload field is not a good idea. You
can try do the following:
def index():
db.define_table('thing',Field('image','upload',requires=IS_NOT_EMPTY()))
form = SQLFORM.factory(db.thing,upload=URL('download')).process()
db.thing.image.default = 'xxx.png'
if form.errors['image'] == '':
del form.errors['image']
insert 'xxx.png' where needed
return locals()
