How do I append gp.fileupload to an existing Shabti
(shabti_formalchemy) application? In particular, how to attach the
middleware?
Using the standard tempita substitution pattern, replace {{package}}
with your app's name:
development.ini
==========
[server:main]
use = egg:Paste#http
host = 127.0.0.1
port = 5000
request_queue_size = 200
[pipeline:main]
pipeline = fileupload {{package}}
[filter:fileupload]
use = egg:gp.fileupload
include_files = fileupload.css jquery.fileupload.*
tempdir = %(here)s/data/fileupload
max_size = 50
upload_to = %(here)s/data/filestorage
# The above specs for fileupload are based on the following:
## temporary directory to write streams to
# tempdir = %(here)s/data/fileupload
## file to inject in the html code
#include_files = fileupload.css jquery.*
## if you already have jquery in your application, use this line
#include_files = fileupload.css jquery.fileupload.*
## max upload size is 50Mo
#max_size = 50
## use this options to also wrap your application with a Storage
middleware
#upload_to = %(here)s/storage
#exclude_paths = /@@
[app:{{package}}]
use = egg:{{package}}
full_stack = true
static_files = true
lang = en
controllers/upload.py
============
import logging
from pylons import request
from {{package}}.lib.base import *
log = logging.getLogger(__name__)
class UploadController(BaseController):
def index(self):
return render('/upload.mako')
def save(self):
log.info('%s', request.POST)
log.info('%s', request.environ)

That's about it., I think.
Be warned though, it seems to prevent evalexception from working. And
although I successfully uploaded and stored files, they weren't big
enough to exercise the Ajax/progress bar issue.
Cheers,
