Issues with uploading images to a carousel [duplicate] - ajax

Django template/view issues with carousel

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? I'm kind of a noob at Django, and writing this code is like pulling teeth.
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="container">
<div class="row">
<div class="col-md-12">
<div id="myCarousel" class="carousel slide" data-ride="carousel">
<div class="carousel-inner" role="listbox">
{% for document in documents %}
<div class="item {% if forloop.first %} active {% endif %}">
<div class="row">
<div class="col">
<li>{{document.docfile.name}}</li>
<img src = "{{STATIC_URL}}img/{{document|filename}}" >
<p align="center"><form style="text-align:center" action="{% url 'webportal:delete' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.Document.label_tag }} {{ form.Document.help_text }}</p>
<p>
{{ form.Document.errors }}
{{ form.Document.docfile }}
</p>
<p><input type="submit" value="Delete" /></p>
</form></p>
</div>
</div>
</div>
{% endfor %}
</div>
<a class="left carousel-control" href="#myCarousel" role="button" data-slide="prev">
<span class="glyphicon glyphicon-chevron-left"></span>
<span class="sr-only">Previous</span>
</a>
<a class="right carousel-control" href="#myCarousel" role="button" data-slide="next">
<span class="glyphicon glyphicon-chevron-right"></span>
<span class="sr-only">Next</span>
</a>
</div>
<!-- /.carousel -->
</div>
</div>
<form action="{% url 'webportal:carousel' %}" method="post" enctype="multipart/form-data">
{% csrf_token %}
<p>{{ form.non_field_errors }}</p>
<p>{{ form.docfile.label_tag }} {{ form.docfile.help_text }}</p>
<p>
{{ form.docfile.errors }}
{{ form.docfile }}
</p>
<p><input type="submit" value="Upload" /></p>
</form>
</div>

# url(r'^role_creation', role_creation.Creation.as_view(), name="role_creation"),

url(r'^accounts/create', accounts.create),
url(r'^accounts/edit', accounts.edit),
url(r'^accounts/remove', accounts.remove),
url(r'^$', views.bootstrap),
)
If there is a way to do this, does it involve ajax? I asked this again because of a lack of an adequate answer.

Answer 1

You should pass the documents context variable to the template in the view which handles the /alzheimers/ page.
UPDATE: The view you should change is the views.boostrap(). So rendering of the template will be something like this:
def bootstrap(request):
...
return render_to_response('webportal/bootstrap.html',
{'documents': Document.objects.all()},
context_instance=RequestContext(request)
)
