Django template/view issues with carousel

Question

OK, so here's the deal:

This is currently what I'm working on:

See the two arrows at the top? That's where a carousel of pictures should be. However, there are no pictures in this carousel. That is, until I click the 'Upload' Button.

So, my goal is to make the pictures appear on the first page before I even click the 'upload' button.

How can I fix this problem?

My code:

Index.html

{% extends 'webportal/defaults.html' %}
{% block body %}
    {% include 'webportal/carousel.html' %}

    <br/>
    <div class="container">
        <div class="row">
            <div class="col-md-12">
                <p> So far we have been able to establish what the user tables will be have created or are in process of
                    creating
                    the ability to create, update, destroy users.</p>
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <p> For now this ability is limited to the main user table, however the models will be easily extended
                    to other
                    tables as they are needed</p>
            </div>
        </div>
        <div class="row">
            <div class="col-md-12">
                <p> Also not a lot of thought has gone into styling yet, we know that the page is suppose to resemble
                    the parent
                    organizations page. Right now we have been more focused on getting each individual component
                    working. Later we
                    will merge them into a whole. </p>
            </div>
        </div>
    </div>


    {% include 'webportal/info_row.html' with one=one two=two three=three %}
{% endblock %}

Carousel.html:

{% load staticfiles %}
{% load filename %}

                           <div class="row">

def delete(request, my_id):
    Deleted=get_object_or_404(Document, docfile=my_id)
    if request.method=='POST':
        form=DeleteForm(request.POST, instance=Deleted)
        if form.is_valid():
            Deleted.delete()

    )

# Redirect to the document list after POST
def carousel(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():

            newdoc.save()

   else:
       form = DocumentForm() # A empty, unbound form
# Load documents for the list page
   documents = Document.objects.all()
#documents=DocumentForm().
# Render list page with the documents and the form
   return render_to_response(
    'webportal/index.html',

)

Models.py:

class Document(models.Model):
    docfile = models.ImageField(upload_to='webportal/static/img/')
class DeleteForm(ModelForm):
    class Meta:
        model=Document
        fields=[]

Forms.py:

class DocumentForm(forms.Form):
    docfile = forms.ImageField(label='Select a file', help_text='max. 42 megabytes')

I wouldn't be surprised if what I'm trying to do is impossible. If there is a way to do this, does it involve Ajax?

Answer 1

The .py files are Python code. In Python, leading whitespace matters.

In Views.py, the carousel function does not contain valid Python code:

def carousel(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect('http://127.0.0.1:8000/alzheimers/')
else:

 form = DocumentForm() # A empty, unbound form
# Load documents for the list page
documents = Document.objects.all()
#documents=DocumentForm().
# Render list page with the documents and the form
return render_to_response(
    'webportal/index.html',
    {'documents': documents, 'form': form,},
    context_instance=RequestContext(request)
)

Instead, it should probably be:

def carousel(request):
    # Handle file upload
    if request.method == 'POST':
        form = DocumentForm(request.POST, request.FILES)
        if form.is_valid():
            newdoc = Document(docfile = request.FILES['docfile'])
            newdoc.save()

            # Redirect to the document list after POST
            return HttpResponseRedirect('http://127.0.0.1:8000/alzheimers/')

    else:

        form = DocumentForm() # A empty, unbound form
        # Load documents for the list page
        documents = Document.objects.all()
        #documents=DocumentForm().
        # Render list page with the documents and the form
        return render_to_response(
            'webportal/index.html',
            {'documents': documents, 'form': form,},
            context_instance=RequestContext(request)
        )

But it is not clear if the else part belongs to the first or the second if construct.
