I'm trying to store the original filename, filetype, and filesize for an
upload field using a smartgrid.
I can add these fields during the insert (by setting the field defaults)
but not update the fields if you update the uploaded file. The edit form
does upload the new file but I don't know how to then update the stored
attributes. The upload field, request.vars.survey, initially contains the
cgi.FieldStorage object during insert (from the new form). However, the
edit form then contains the string for the new filename in
request.vars.survey unless their is a new file submitted. But I don't know
how to update the stored file attributes for the form before the smartgrid
processes the updated upload file.
db.define_table('person',
Field('first_name'),
Field('last_name'),
auth.signature,
format = '%(first_name)s %(last_name)s'
)
db.define_table('contracts',
Field('person', 'reference person'),
Field('survey_filename', writable=False),
Field('survey_filetype', writable=False),
Field('survey_filesize', 'integer', writable=False),
Field('survey', 'upload', autodelete=True),
Field('description'),
auth.signature
)
def index():
if request.vars.survey != None and not type(request.vars.survey) is str:
db.contracts.survey_filename.default = request.vars.survey.filename
db.contracts.survey_filesize.default = request.env.content_length
db.contracts.survey_filetype.default =
request.vars.survey.filename.split('.')[-1]
grid=SQLFORM.smartgrid(db.person)
return dict(grid=grid)
