Importing the user.id in form.

Hi,

I defined a model which has a 'ForeignKey' to the 'User' .

models.py :

class Design(models.Model):

title = models.CharField(max_length=100)

designer=models.ForeignKey(User)

description = models.TextField(null = True)

def __unicode__(self):

return self.title

forms.py :

class UploadForm(forms.ModelForm):  

    class Meta:

        model = Design

        fields = ('title','description')

views.py :

def me(request):

    if request.POST:

        form = UploadForm(request.POST, request.FILES)

        if form.is_valid():

            form.save()

            return HttpResponseRedirect('/home/')

        else:

            return render_to_response('home/invalid.html')

    else:

        form = UploadForm()

        args = {}

        args.update(csrf(request))

        args['form'] = form

        return render_to_response('home/upload.html', args,context_instance=RequestContext(request))

Now when I save the save the form, the 'designer=models.ForeignKey(User)' raises an error "Column 'designer_id' cannot be null"  .
A user after logging in can upload a new design.

How to store the " designer_id " i.e, the user.id  of the user who uploaded the design?

Can someone help me!!
