Hi everyone,
I am stuck with an issue - please refer to the code below.
1. I have a form (new_entry function) that I will like to use to be able
to upload a file among other fields.
2. I am using FORM instead of SQLFORM because one of the dropdown fields
(line 11) in the form is generated at run time.
3. The way that I did was to use input file type (line 9) to open a file
selection browser / window to select the file - this works OK.
4. If form.vars.uploadfile is not empty, it means that a file had been
selected for uploading.
5. I will the want to copy the file into application/<app name>/upload
folder using shutils (lines 17-25) but the file name will be changed to
entry.file.<random number>.<original file name>
6. However, this does not work as I get the error that the file is not
found.
7. For debugging, I print the source file name (line 21) and it only gave
me the file name when I will need the entire file path for shutil.copy2()
at line 25 to work.
*Can someone assist?*
Any help will be greatly appreciated.
Thank in advance and warm regards
Maurice Ling
