Django Requiring Optional Form Field Error - django

Question

To new readers: Neverwalkaloner's solution solved the initial error but the photo upload is still required and making required false in forms.py gives me a MultiValueDictKeyError. Any help on making it optional would be greatly appreciated.
I have a model and form to upload either a picture and text, or just text. My intention, actually was to make it a choice between an image, text or both and any help with that would be appreciated, but I digress. Uploading only works when an image is included, if it is just text, I get the error:
The view lesyeux.views.posts didn't return an HttpResponse object. It
returned None instead.The view lesyeux
My model is:
class Post(models.Model):
image = models.ImageField(upload_to='uploaded_images', blank=True,
null=True)
text_post = models.CharField(max_length=1000)
author = models.ForeignKey(User)
My form is:
class PostForm(forms.ModelForm):
image = forms.FileField(label='Select an image file',
help_text='Please select a photo to upload')
text_post = forms.CharField(help_text="Please enter some text.")
class Meta:
model = Post
fields = ('image', 'text_post',)
exclude = ('author',)
My view is:
def posts(request, id=None):
neighborhood = get_object_or_404(Neighborhood, id=id)
form = PostForm()
if request.method == 'POST':
form = PostForm(request.POST, request.FILES)
if form.is_valid():
post = Post(image = request.FILES['image'])
post = form.save(commit=False)
post.author = request.user
post = post.save()
next = request.POST.get('next', '/')
return HttpResponseRedirect(next)
else:
form = PostForm()
posts = Post.objects.all().order_by('-id')
return render(request, 'posts.html', context = {'form':form,
'posts':posts, 'neighborhood':neighborhood})
and my form is:
<form id="PostForm" method="post" action="/view/{{ neighborhood.id }}/posts/" enctype="multipart/form-data">
{% csrf_token %}
{% for hidden in form.hidden_fields %}
{{ hidden }}
{% endfor %}
{% for field in form.visible_fields %}
{{ field.errors }}
{{ field.help_text }}
{{ field }}
{% endfor %}
<input type="hidden" name="next" value="{{ request.path }}">
<input type="submit" name="submit" value="Post" />
</form>

Your view doesnt return response if form is not valid. To fixt it rewrite view like this:
def posts(request, id=None):
neighborhood = get_object_or_404(Neighborhood, id=id)
form = PostForm()
if request.method == 'POST':
form = PostForm(request.POST, request.FILES)
if form.is_valid():
post = Post(image = request.FILES['image'])
post = form.save(commit=False)
post.author = request.user
post = post.save()
next = request.POST.get('next', '/')
return HttpResponseRedirect(next)
else:
form = PostForm()
posts = Post.objects.all().order_by('-id')
return render(request, 'posts.html', context = {'form':form, 'posts':posts, 'neighborhood':neighborhood})
