I've been wracking my brain over this for the last few days now and haven't been able to find much in the way of help for my specific issue. Here's my setup.
Windows 7
IIS 7.5
Helicon Zoo 3.1.98.508
Django 1.6.3
Python 2.7.3
I should state that I'm new to Django and Helicon Zoo.
What's happening is that while I seem to have no issue uploading a file under the default of 2.5mb, I cannot get chunks to upload correctly for anything over this amount. While I'm sure I could up this limit in my settings file, I'd really rather not as for my purpose I could see needing to upload larger files than what I would really want being handled by memory.
What I'm seeing when I attempt this is a rather uninformative Error 500 from Helicon Zoo about some missing headers
Worker Status
The process was created
Windows error
The operation completed successfully. (ERROR CODE: 0)
Internal module error
message: HTTP-headers - are expected
type: ZooException
file: Jobs\JobFastCgi.cpp
line: 391
version: 3.1.98.508
STDERR
Empty stderr
At first, I thought maybe it was something to do with the temp folder so I set
FILE_UPLOAD_TEMP_DIR = [os.path.join(BASE_DIR, 'temp')]
in my settings file, but it didn't seem to do anything useful.
I then discovered how to enable logging for django which really opened things up to me. I know now where the error is coming from.. but I have no clue what I'm supposed to do to get around it..

What does this mean? Are my chunks coming in as a list object somehow and I don't realize it?
Here's my code for the app, it's included in my Blog app I made since it's my main app and it seemed simpler than creating an app all it's own. Was that a mistake?
forms.py
from django import forms
class UploadFileForm(forms.Form):
title = forms.CharField(max_length=50)
file = forms.FileField()
views.py
from django.shortcuts import render, render_to_response
from django.http import HttpResponse, Http404, HttpResponseRedirect
from django.template import RequestContext, loader
from blog.forms import UploadFileForm
from blog.models import Blog
from blog.uploads import handle_uploaded_file
def index(request):
latest_blog_list = Blog.objects.order_by('-pub_date')[:5]
template = loader.get_template('blog/index.html')
context = RequestContext(request, {
'latest_blog_list': latest_blog_list,
})
return HttpResponse(template.render(context))
def detail(request, blog_id):
try:
blog = Blog.objects.get(pk=blog_id)
except:
raise Http404
return render(request, 'blog/detail.html', {'blog': blog})
def upload_file(request):
if request.method == 'POST':
form = UploadFileForm(request.POST, request.FILES)
if form.is_valid():
handle_uploaded_file(request.FILES['file'])
#form.save()
return HttpResponseRedirect('/upload/')
else:
form = UploadFileForm()
return render_to_response('upload/upload.html', {'form': form}, context_instance=RequestContext(request))
uploads.py
import os
saveDir = 'E:\\uploads\\'
def handle_uploaded_file(f):
#logging.debug('upload_here')
if f:
destination = open(saveDir + f.name, 'wb+')
for chunk in f.chunks():
destination.write(chunk)
destination.close()
app urls.py
from django.conf.urls import patterns, url
from blog import views
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^(?P<blog_id>\d+)/$', views.detail, name='detail'),
url(r'^upload/$', views.upload_file, name='upload'),
)
project urls.py
from django.conf.urls import patterns, include, url
from django.conf import settings
from django.conf.urls.static import static
from django.contrib import admin
admin.autodiscover()
urlpatterns = patterns('',
# Examples:
# url(r'^$', 'project.views.home', name='home'),
# url(r'^blog/', include('blog.urls')),
url(r'^/?', include('blog.urls', namespace="blog")),
url(r'^admin/', include(admin.site.urls)),
url(r'^upload/', include('blog.urls', namespace="upload")),
)
I should also note that portions of these large files are actually appearing in my upload location, but nothing more than 1 meg in size. It's like the process stops before it's actually done for some reason. I then have to stop and restart IIS to get the site to even function again.
