So, I have a system where users can either choose from an already existing image gallery, or upload a new image to be processed and saved.

First off, the model:

class Post(models.Model):
    image = models.ForeignKey(Image, null=True, blank=True)
    title = models.CharField(max_length=200)
    slug = models.CharField(max_length=200, unique=True, blank=True)
    description = models.TextField(blank = True)
    text = models.TextField()

    def __str__(self):
        return self.title

and our form

class PostForm(BaseModelForm):
    new_image = forms.ImageField(required=False)

    def clean(self):

        return self.cleaned_data

class Meta:
    model = Post
    fields = ('title','text', 'image', 'new_image', description')

    help_texts = {
       'new_image': _('either upload a new image, or choose from the gallery')
    }

so then our view where it gets processed

def post_new(request):
    if request.method == "POST":
        form = PostForm(request.POST, request.FILES)
        if form.is_valid():
            post = form.save(commit=False)
            post.author = request.user
            post.slug=slugify(post.title)
            if form.cleaned_data.get('new_image'):
                image = Image(title=post.title, description=post.description, image = request.FILES['new_image'])
                image.save()
                post.image = image


            post.save()
            return redirect('post_detail', pk=post.pk)
    else:
        form = PostForm()
    return render(request, 'blog/post_edit.html', {'form': form})

Now what this should be doing is creating a new image object out of the form field, then saving it to the foreignkey constraint on the post model. But what it does is nothing, the post uploads fine with a blank image field, and the image never gets created. This makes me think the if statement for 'new_image' is resolving to False but I can't figure out why it would do that.

Also, for conventions sake, should this be happening in the form class or the view class?

also, my image model

class Image(models.Model):
    title = models.CharField(max_length=200)
    description = models.TextField()
    image = models.ImageField(upload_to = 'images/', default =     'images/None/no-img.jpg')
    def __str__(self):
        return self.title
