Here is how I do it, Model, Form, View. The Django file form can
process a bunch of this but I am capturing some metadata that is NOT
on the forms so have to do that after form processing then do a
separate save().
Note that my models are inheriting from some abstract base classes
which provide tracking and hierarchy relationships, but you can see
what the upload part is doing fairly clearly.
The model:
class File(FileDropContent):
file = models.FileField(upload_to=FILEDROP_ROOT)
mime_type = models.CharField(_('mime_type'),
max_length=127)
downloaded = models.DateTimeField(_('last download date'),
null=True)
expiration = models.DateTimeField(_('expiration date'), )
parent = models.ForeignKey(Container,
related_name='files', null=True)
def is_expired(self):
return self.expiration < datetime.datetime.now()
The form:
class FileForm(forms.ModelForm):
"""
Upload File, select file from filesystem browser, get expriation
description from user.
"""
def __init__(self, *args, **kwargs):
"""
Fix field order here too.
"""
super(FileForm, self).__init__(*args, **kwargs)
description = self.fields.pop('description')
new_pos = len(self.fields)
self.fields.insert(new_pos, 'description', description)
class Meta:
model = File
fields = ['file', 'expiration', 'description']
And the view:
def file_create(request, parent_id):
"""
Get upload file and metadata (e.g. true name), save file to disk.
"""
parent = Container.objects.get(pk=parent_id)
if not _is_writable(request.user, parent):
return HttpResponse("You don't have permission to upload a
file into parent '%s'" % parent)
if request.method == "POST":
form = FileForm(request.POST, request.FILES)
if form.is_valid():
uploadobj = form.save(commit=False)
uploadobj.parent = parent
uploadobj.title = request.FILES['file'].name
uploadobj.mime_type = request.FILES['file'].content_type
uploadobj.creator = request.user
uploadobj.ip = request.META.get('REMOTE_ADDR',
"0.0.0.0")
uploadobj.save()
return HttpResponseRedirect(reverse("file_detail",
args=[uploadobj.pk]))
