The way i solved it was by changing the data in my view.
Mind that i also save the image file manually.
But it works.
I get the user data because i use the authentication layer of Django.
It's described in the docs.
If you want to validate the size of the image for instance,
add this function to the ImageForm:
def clean_image(self):
# validate data here
return self.clean_data["image"]
This is the form and the view function:
class ImageForm(forms.Form):
name = forms.CharField(max_length=60)
image = forms.Field( widget=forms.FileInput() )
def add_icon(request):
if request.method == 'POST':
form = ImageForm(request.POST)
# prepare the variables to manage the path of the image
sep = os.path.sep
userpart = "%s_%s" % (request.user.id,request.user.username)
filename = 'icon_%d.jpg' % request.user.id
image_path = "img" + sep + userpart + sep + "icons" + sep
form.data["image"] = image_path + filename
if form.is_valid():
icon = form.save(commit=False)
new_data = request.POST.copy()
# if we have an image, upload it
if new_data.get('image', None):
# create the path, make the dirs
path = settings.MEDIA_ROOT + sep + image_path
os.makedirs(path)
path = path + filename
# save the image
try:
fout = file(path,'wb')
fout.write(request.FILES["image"]["content"])
finally:
fout.close()
icon.save()
return HttpResponseRedirect("/")
else:
errors = new_data = {}
form = ImageForm()
return render_to_response('main/icon/add_icon3.html',
{'form': form, 'user':request.user.id},
context_instance=RequestContext(request))
