I have the following:
## MODELS
class Category(models.Model):
user = models.ForeignKey(User)
name = models.CharField(max_length=200)
class Link(models.Model):
user = models.ForeignKey(User)
category = models.ForeignKey(Category)
name = models.CharField(max_length=255)
url = models.URLField(max_length=255)
## FORMS
class CategoryField(forms.Field):
def clean(self, value):
if not value:
raise forms.ValidationError('This field is required.')
try:
category = Category.objects.get(user=???, name=value)
except Category.DoesNotExist:
category = Category(user=???, name=value)
category.save()
return category
class LinkForm(ModelForm):
category = CategoryField()
class Meta:
model = Link
exclude = ('user', 'url')
## VIEWS
def create(request):
if request.method == 'POST':
form = LinkForm(request.POST)
if form.is_valid():
link = form.save(commit=False)
link.user = request.user
link.save()
return HttpResponseRedirect(reverse('link_list'))
else:
form = LinkForm()
return render_to_response(
'links/link_form.html', {
'form': form,
},
context_instance=RequestContext(request)
)
What I don't see is a way to get the user up into my field the way I
have things set up. I originally didn't have a user FK on the
Category model but decided I wanted it so that when adding new Links,
the Categories can be filtered by user so each user sees only their
categories.
I'm stuck here. Any help is much appreciated.
Thanks,
Rob
