Hi :)
I'm trying to validate an uploaded image's size and filetype.
However i have problems even gettings to the validation as django
keeps telling me that there's no object.
When i don't use the validation part I can upload an image just fine.
So the upload thing works.
I just can't figure out how to pass on the file to the validation
part.
I have tried with several approaches I have found on the internet.
Therefore i will list my view, model and the two form methods i have
tried.
first, my view:
def upload_file(request):
myprofile = request.user.get_profile()
current = request.user
print "upload 1"
if request.method == 'POST':
form = AvatarForm(request.POST,
request.FILES,instance=myprofile)
print "upload 2"
if form.is_valid():
[...]
model:
class Avatar(models.Model):
user = models.ForeignKey(User,unique=True,editable=False)
photo = models.ImageField(upload_to=get_profile_path, blank=True,
null=True)
thumbnail = models.ImageField(upload_to='profile_thumb', blank=True,
null=True)
form:
class AvatarForm(ModelForm):
class Meta:
model = Avatar
#1
def clean(self,data,initial=None):
content = super(ImageField, self).clean(self,data,initial)
content_type = content.content_type.split('/')[0]
if content_type in settings.CONTENT_TYPES:
if content._size > settings.MAX_UPLOAD_SIZE:
raise forms.ValidationError(_('Please keep
filesize under %s.
Current filesize %s') % (filesizeformat(settings.MAX_UPLOAD_SIZE),
filesizeformat(content._size)))
else:
raise forms.ValidationError(_('File type is not
supported'))
return content
#2
def clean(self):
if 'photo' in self.cleaned_data:
photo = self.cleaned_data['photo']
print photo
if photo.get('content-type') != 'image/jpeg':
msg = 'Only .ZIP archive files are allowed.'
raise forms.ValidationError(msg)
return photo
The error i get is pretty much the same with both methods. Nonetype
has nu method/attribute: content_type/get... So i don't know if the
rest of the validation code works since I can't pass my file through
to the validation :-(
Any help is appreciated :-)
And a good weekend to all of you
