So if I have this field in db.project
Field('project_pdf', 'upload', label='Project PDF', comment='', uploadfolder
='app/uploads'),
I must change to
Field('project_pdf', 'upload', label='Project PDF', comment='', uploadfolder
='app/uploads', default=''),
what content should I put in "default" attribute?
the file name? or folder path?
records have same folder path but different file name.
Even if I change "form.var.project_pdf", the link button won't appear?
