Django file upload returns None

I'm trying to learn Python and Django, when I try to upload a file in my form Django detect my file as "None".
forms.py:
from django import forms
class FormularioTrabajo(forms.Form):
email = forms.EmailField(label="Correo Electrónico:", max_length=254)
Currículum = forms.FileField()
views.py:
In views I want to save the file uploaded in the directory /media/
def trabaja(request):
if request.method == 'POST':
form = FormularioTrabajo(data=request.POST, files=request.FILES)
if form.is_valid():
file = request.FILES.get('file', None)
if file is not None:
file_name = file.name
file_path = '/media/' + file_name
with open(file_path, 'wb+') as destination:
for chunk in file.chunks:
destination.write(chunk)
form.save()
return HttpResponseRedirect(reverse("miapp:index"))
else:
return HttpResponse('None')
else:
form = FormularioTrabajo()
return render(request, "web/trabajar.html", {'form':form})

notice the href of css and js link tag.
There are a few things that I have seen here that don't look correct. Number 1, Are you inheriting your template from your base?
{% extends 'base.html' %}
This is where you should call your materialize.css (in the base template)
Load static is in the wrong place, you are calling static after the link to the css, load static should be at the very top of the template:
{% extends 'base.html' %} {% load static %}
You have an extra opening chevron in your DOCTYPE.
Put materialize js in you base template before closing body tag. Django by default inherits the default base template so this is what you could be missing.
In case I have misunderstood, and you are only wanting to call materialize.css for that header template you can use tags after the call for load static
{% block extra_css %}<link rel="stylesheet" href="{% static 'main/materialize.css' %}"> {% endblock extra_css %}
This might help:
{% load static %} above doctype tag!
{% load static %}
<!DOCTYPE html>
<html>
<head>
<meta charset="utf-8">
<!--Import Google Icon Font-->
<link href="https://fonts.googleapis.com/icon?family=Material+Icons" rel="stylesheet">

Django 1.9. template inheritance. Block doesn't display

I have 2 html pages in my Django templates. I am trying to insert cats.html in index.html as a block, but nothing happens. No errors, no display. I already looked in django documentation and in the youtube. Just can't understand where is problem
index.html:
{% load static %}
<!DOCTYPE doctype html>
<html class="no-js" lang="en">
<head>
<meta charset="utf-8"/>
<meta content="width=device-width, initial-scale=1.0" name="viewport"/>
<link rel="stylesheet" type="text/css" href="{% static 'items/index-style.css' %}" />
<title>

</title>
</head>
<body>
{% block cats %}
{% endblock cats %}
</body>
</html>
cats.html:
{% extends "index.html" %}
{% block cats %}
<div class="row column">
<p class="lead">
Категории товаров
</p>
</div>
<div class="row small-up-1 medium-up-2 large-up-3">
{% for category in categories %}
<div class="column">
<a href="/{{category.alias}}">
<div class="callout">
<p>
{{category.name}}
</p>
<p>
<img alt="image of a planet called Pegasi B" src="{{category.image}}"/>
</p>
<p class="lead">
<!-- Цена: {{tovar.price}} -->
</p>
<p class="subheader">

</p>
</div>
</a>
</div>
{% endfor %}
</div>
{% endblock cats %}
views.py:
from django.shortcuts import render
from django.http import HttpResponse, Http404
from django.template.loader import render_to_string
from items.models import *
# Create your views here.
def home(request):
try:
categories = Category.objects.all()
except:
raise Http404()
context = {
'categories':categories,
}
return render(request,"index.html",context)
You are confusing the block name with template name. You are not inserting cats.html into index.html as you expect, but you are extending index.html in your cats.html. You should use your child template (cats.html) in your view, ie change the last line to:
return render(request, 'cats.html', context)
actually the problem is you use index.html as a base template
and then inherit in your cats.html
so you have to render cat.html to get the desired result THIS IS HELPFUL FOR YOU
return render(request, 'cats.html', context)
thanks :)

Upload a file, having problems with the url in Django

I'm doing a function to upload a file with a example that I found here on Stack Overflow, everything works fine, the problem is that when I try to access the document by a URL, the click sends me to the app url not the photo url, for example I'm trying to access to this

and it should be the image URL

You are accessing a model not an image. Also, this might help:
https://docs.djangoproject.com/en/1.2/howto/static-files/
Please take a look there as i don't see this added to the urls.py you pasted.
