Hi,
I've seen quite a few examples showing various ways to create a form using
manytomany relationships and save the data, but i'm still missing a key
piece of the puzzle.
I've created a form and it "works", meaning the form creates a new Item
object and associates the user.
However i'm not sure how to go about saving the item category and item
components selected in the form.
I've tried quite a few things over the last week and i know its quite easy,
but just haven't quite gotten there yet and would appreciate some guidance.
FORM:
class NewItemForm(ModelForm):
class Meta:
model = Item
fields = ('name', 'desc', 'img','category','components')
def save(self, user, component commit = True):
"""Append the component list to the item"""
new_item = super(NewItemForm, self).save(commit = Fals
if commit:
new_item.save()
# new_item.save_m2m()
new_item.user.add(user)
if component != "none":
new_item.category.add(new_item)
new_item.components.add(new_item)
return new_item
VIEW:
def create_item(request):
if request.method == "POST":
form = NewItemForm(request.POST, instance=item())
if form.is_valid():
form.save(request.user, "none")
return HttpResponseRedirect(reverse('nav.views.dashboard'))
else:
form = CategoryForm(instance=item())
return render_to_response('objects/create_item.html', {'item_Form':
form}, context_instance=RequestContext(request))
MODEL:
class Item(models.Model):
#
def __unicode__(self): # Python 3: def __str__(self):
return self.name
name = models.CharField(max_length=32)
desc = models.CharField(max_length=254)
img = models.CharField(max_length=32)
user = models.ManyToManyField(User)
components = models.ManyToManyField(component)
category = models.ManyToManyField(Category)
