I'm using a CustomUploadHandler for one of my views, but the form is
always invalid - also request.FILES is also blank ?
I'm a bit new to django, so not entirely sure whats going on
## form
class UploadMidletPairForm(ModelForm):
class Meta:
model = MidletPair
### uploadhandler
class CustomUploadHandler(FileUploadHandler):
def __init__(self, request = None, upload_to = tempfile.gettempdir
()):
self.upload_to = upload_to
FileUploadHandler.__init__(self, request)
def new_file(self, field_name, file_name, content_type,
content_length, charset=None):
#if not is_valid_upload(file_name): # here you can use
a function to filter uploaded files.
# raise UploadFileException , "forbidden file type"
if not os.path.exists(self.upload_to):
os.makedirs(self.upload_to)
elif not os.path.isdir(self.upload_to):
raise IOError("%s exists and is not a directory." %
self.upload_to)
outPath = os.path.join(self.upload_to, file_name)
self.destination = open(outPath, 'wb+')
FileUploadHandler.new_file(self, field_name, file_name,
content_type, content_length, charset)
def receive_data_chunk(self, raw_data, start):
self.destination.write(raw_data)
def file_complete(self, file_size):
self.destination.close()
### view
@login_required
def validate_build(request):
'''
Jad/Jar upload form
'''
# Save the file to disk
print >> sys.stderr, request.user
request.upload_handlers = [CustomUploadHandler(upload_to =
os.path.join(settings.MEDIA_ROOT, 'superglu', 'userdata', str
(request.user), 'validate'))]
UPLOAD_FORM_TITLE = 'Validate Build'
if request.method == 'POST':
form = UploadMidletPairForm(request.POST, request.FILES)
if form.is_valid():
print >> sys.stderr, 'is valid'
jad = request.FILES['jad_file']
jar = request.FILES['jad_file']
else:
print >> sys.stderr, 'is not valid'
print >> sys.stderr, form.errors
else:
form = UploadMidletPairForm()
return render_to_response('validate/build/index.html',
context_instance = RequestContext(request,\
{
'form': form,
'title': UPLOAD_FORM_TITLE,
}))
### template
{% extends "base.html" %}
{% load i18n %}
{% block breadcrumbs %}
<div class="breadcrumbs">
<a href="../">{% trans 'Home' %}</a> ›
<a href="/validate/">Validate builds</a> ›
<a href="/validate/">Build</a> ›
</div>
{% endblock %}
{% block content %}
<div id="content-main">
{% if perms.validate %}
<h2>Upload Jad/Jar pair</h2>
<form action="." method="post" enctype="multipart/form-data">
<fieldset>
{% if form.image.errors %}
<ul class="errorlist">
{% for error in form.image.errors %}
<li>{{ error|safe }}</li>
{% endfor %}
</ul>
{% endif %}
{{ form }}
</fieldset>
<input type="submit" value="Validate" />
</form>
{% else %}
Sorry, your user is not enabled for validation
{% endif %}
</div>
{% endblock %}
