I have not tried it but you can do class EncryptedField(Field): def __init__(self,*a,**b): self.password = b['password'] del b['password'] Field.__init__(self,*a,**b) def store(self,file, filename=None, path=None): newfile = encrypt(file,self.password) return Field.store(self,file,filename,path) def retrieve(self, name, path=None): (filename, file) = Field.retrieve(self,name,path) newfile = decrypt(file,self.password) return (filename, newfile)
the use db.define_table('person',Field('name'),EncryptedField('secret','upload',password='too many secrets!'))
