Hi Val and Dave,
Have a look at the code below - the line foto_path=... below works but it
uploads the photos to "web2py\applications\artpicstatic\user_uploads"
folder instead of web2py\applications\artpic\static\user_uploads folder. It
also generates the thumbnail file. Now if I use *foto_path =
os.path.join(request.folder + "static/user_uploads/" + upload_pic)* it
shows the right path after normalization but does not upload the photo at
all. And since it does not upload the photo the rest of the code fails to
generate thumbnails etc and throws this error . m using windows 10 with
python 2.7.13
- <type 'exceptions.IOError'> [Errno 2] No such file or directory:
'E:\\web2py_src\\web2py\\applications\\artpic\\static\\user_uploads\\fotoz.upload_photo.82bfeee5a1affabd.3033372e4a5047.JPG'
CODE:
-------
#foto_path = (request.folder + "static/user_uploads/" + upload_pic)
print ("----------------")
foto_path = (request.folder + "static/user_uploads/" + upload_pic)
print "Foto Path: ", foto_path
normal_foto_path = os.path.normpath(foto_path)
print "Normal Foto Path: ", normal_foto_path
infile = normal_foto_path
print "infile: " , infile
thumbnail_filename = ("%s" % recordsID + ".thumbnail.jpg")
print "thumbnail_filename :", thumbnail_filename
outfile_path = os.path.join(request.folder, "static/thumbs/" +
thumbnail_filename)
print "outfile_path: ", outfile_path
normal_outfile_path = os.path.normpath(outfile_path)

CODELISTING IS ATTACHED
Looks like a simple answer but feels like my code is badly written...
