I have a situation that is confusing me. I have a form to upload a
file. From my understanding, when 'clean' is called on the form, the
'file1' field should have already been cleaned and available in
cleaned_data. However, under some circumstances it is, sometimes not.
But when calling is_valid I can get
None
None
None
Total size 0
Which means the file1 was not cleaned. Here is my code..
Shouldn't the file1 be available in cleaned_data to check its size at
this point always?
If not, how can I access the request.FILES from inside the form rather
than the view?
---
(in view)
document_form = DocumentFileUploadForm(request.POST, request.FILES)
if document_form.is_valid():
...
(in forms)
def check_file_size_limit(form):
# calculate and check total size of files on form is not exceeded
size = 0;
for i in range(1, 4):
f = form.cleaned_data.get("file%d" % (i,))
print f
if f is not None:
size += f.size # UploadedFile object is much easier now
print "Total size %d" % (size,)
if size > settings.MAX_FILE_SIZE:
raise ValidationError("Total file size exceeds the allowed
limit")
return size
class DocumentFileUploadForm(forms.Form):
file1 = forms.FileField(label="Upload CV / Folio", required=False)
def clean(self):
size = check_file_size_limit(self)
if size == 0:
raise ValidationError("Please attach a CV!")
return self.cleaned_data
