Hi,
Web.py-Noob here :-)
I am trying to upload images to a web.py 0.31 instance through a
simple form template (along the lines of the examples given in
http://webpy.org/cookbook/fileupload and http://webpy.org/cookbook/storeupload
Only difference is that the form is in a seperate template, not
defined in the main web.py code.
On submitting the form, I receive an UnicodeDecodeError:
Traceback (most recent call last):
[...]
File "/usr/lib/python2.5/site-packages/web.py-0.31-py2.5.egg/web/
utils.py", line 123, in unicodify
if _unicode and isinstance(s, str): return safeunicode(s)
File "/usr/lib/python2.5/site-packages/web.py-0.31-py2.5.egg/web/
utils.py", line 231, in safeunicode
return obj.decode(encoding)
File "/usr/lib/python2.5/encodings/utf_8.py", line 16, in decode
return codecs.utf_8_decode(input, errors, True)
UnicodeDecodeError: 'utf8' codec can't decode byte 0xff in position 0:
unexpected code byte
I am aware that this issue has been discussed before (eg in
http://groups.google.com/group/webpy/browse_thread/thread/a828612a5e51004b/1e1c6af57e9b14cd
). I have also tried the approach described in http://webpy.org/cookbook/forms
- to no avail but a slightly different sounding unicode error
traceback.
I'd appreciate any feedback on this issue.
Thanks,
Mats
# the class calling the form:

id)[0]

directory you want to store the file in.
web.debug(filepath)

filepath=x.myfile.filename.replace('\\','/') # replaces
the windows-style slashes with linux ones.

the last part (the filename with extension)
fout = file(filedir +'/'+ filename,'w') # creates the file
where the uploaded file should be stored
fout.write(x.myfile.file.value) # writes the uploaded file
to the newly created file.
fout.close() # closes the file, upload complete.
raise web.seeother('/detail?id=%s' % self.id)
# the template:

<input type="submit" />
</form>
