Ok I will post some code here to show as much as possible here is the db definition:
db.define_table('papers', Field('title','string'), Field('author','string'), Field('file','upload'), ) then if i try to use the database administration tool available in Models section and try to insert a file like "The Pricing of Options and Corporate Liabilities_Journal of Political Economy.pdf" i then get a ticket complaining about IOError: [Errno 2] No such file or directory: C:\\Users\\M\\Desktop\\web2py_src\\web2py\\applications\\Library/ databases\\..\\uploads\ \papers.file.a33b16f5af29f6d8.5468652050726963696e67206f66204f7074696f6e7320616e6420436f72706f72617465204c696162696c69746965735f4a6f75726e616c206f6620506f6c69746963616c2045636f6e6f6d792e706466.pdf' i also checked the file actually has never been properly uploaded ( it is not present in the upload directory). Nothing special about size of the file ( if i just change manually the filename it works ). So it seems that the bug is when we receiving the file . hope we can sort this out Thx all M
