Re: [web2py] Re: delete uploads with SQLFORM.factory
Hi, I had a look at sqlform.py, the error comes from the fact that if a
default value is set for the field upload, web2py tries to read it and
store it as the new value for the upload field. As a result it is not
possible to me to edit forms and remove uploads by setting the default
value, this trick doesn't work.
Moreover, I tried to fix the initial error about the missing file, by
setting db.test_img['picture'].default equal to real path of the file.
This worked well but than, if I understood correctly how web2py works, it
tried to store again the default value as the new value, starting a kind of
loop! That was wrong, and actually this has never worked, it stopped due to
the 'error filename' to long.
The good thing is that by changing this two line (line 1394 of sqlhtml.py)
f = self.table[fieldname].default or ''
fields[fieldname] = f
to:
fields[fieldname] = self.table[fieldname].default
It seems that this solved the issue, but of course, I need something better.

Hi Massimo, thank for the answer, I updated the code but the problem is
still there, I made several tests, no one figured out what is wrong. So
that I tried to simplify the code as follows:
db.define_table('test_img',
Field(picture, upload,
uploadfolder=os.path.join(request.folder,'uploads','pictures'),
uploadseparate=True),
Field('created_on', 'datetime', default=request.now, writable=False)
)
def sqlform_add():
form = SQLFORM.factory(db.test_img, _class='well',
upload=URL('default', 'download'),
uploadfolder=os.path.join(request.folder,
'uploads','pictures'),
uploadseparate=True, table_name='test')
if form.process(dbio=False).accepted:
id = db.test_img.insert(**dict(form.vars))
return response.render('generic.html', dict(form=form))
def sqlform_edit():
img = db(db.test_img.id0).select().first()
db.test_img['picture'].default = img['picture']
form = SQLFORM.factory(db.test_img, _class='well',
upload=URL('default', 'download'),
uploadfolder=os.path.join(request.folder,
'uploads','pictures'),
uploadseparate=True, table_name='test')
if form.process(dbio=False).accepted:
print 'form accepted'
return response.render('generic.html', dict(form=form))
what I got:
- adding an img with sqlform_add and then removing it with appadmin --
worked
- adding an img with appadmin and then removing it with sqlform_edit --
failed
- using both sqlform_add and sqlform_edit -- failed
Now I am thinking about the way I set the default value, maybe for a field
as an upload I have to set something more?

[web2py] Re: delete uploads with SQLFORM.factory
Hi, I thought about the option requires, right now I have:
requires=[IS_IMAGE(), IS_UPLOAD_FILENAME(extension='jpg|jpeg|png'), IS_IMAGE
(extensions=('jpeg', 'png'))
I thought that as defined, the field could not be empty, so, I tried to
remove any constrain
requires=None
but then the delete button is no longer shown, why ?!
I've also tried:
requires=[]
but in this case I got the same error as in the other cases.
