Django simple categories list

Sorry for asking such a simple question, but I got stuck on (as I think) this trivial problem. I have a simple gallery model in Django and want to get a category list for photos. My model looks like this:

class Photo(models.Model):
    title = models.CharField(max_length=150)
    image = models.ImageField()
    description = models.TextField()
    category = models.IntegerField(choices=CATEGORIES)
    published = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return self.title

And the choices.py file looks like this:

CATEGORIES = (
    (1, ('Mountains')),
    (2, ('Animals')),
    (3, ('Macro')),
    (4, ('People'))
)

What I'm looking for is getting a list like this:

Mountains | Animals | Macro | People

in my templates.

You need to create model form for this,

models.py

CATEGORIES = (
    (1, 'Mountains'),
    (2, 'Animals'),
    (3, 'Macro'),
    (4, 'People')
)

class Photo(models.Model):
    title = models.CharField(max_length=150)
    image = models.ImageField()
    description = models.TextField()
    category = models.IntegerField(choices=CATEGORIES)
    published = models.DateTimeField(default=timezone.now)

    def __str__(self):
        return self.title

form.py

from django import forms
from .models import Photo

class PhotoModelForm(forms.ModelForm):
    class Meta:
        model = Photo
        fields = ['__all__']

views.py

from django.shortcuts import render
form .forms import PhotoModelForm
def index(request):
    if request.POST:
        form = PhotoModelForm(request.POST)
        if form.is_valid():
            form.save()
    else:
        form = PhotoModelForm()
    return render(request, 'template.html', {'form': form})

template.py:

<form method="POST">
    {% csrf_token %}
    {{form}}
    <input type="submit" value="ok"/>
</form>

What I'm looking for is getting a list like this:

Mountains | Animals | Macro | People

Create New form like,

 class PhotosForm(forms.Form):
        category = forms.ChoiceField(choices=CATEGORIES)

Add view to views.py

def show_list(request):
    context = {}
    if request.POST:
        form = PhotosForm(request.POST)
        if form.is_valid():
            photos = Photo.objects.filter(category=form.cleaned_data['category'])
            context['photos'] = photos
    else:
        context['form'] = PhotosForm()
        context['categories'] = dict((x, y ) for x, y in CATEGORIES)
    return render(request, 'template1.html', context)

And at last you need to add template,

{% if photos %}


<display pics>

{% else %}


{% for key, value in categories %}

     <a href='showpics?id={{key}}'>{{value}}</a>

{% endfor %}

And last showpics should be point to show_list
