django templates index of array does not work

Question

Index in templates of django is like this: {{somearray.i}} for my code this is not working!!

this is views.py

def fadakpage(request):
    tours = tour.objects.order_by('tourleader')
    travelers = traveler.objects.order_by('touri')
    j=0
    for i in tours:
        j+=1
    args={'tours':tours,'travelers':travelers,'range':range(j)}
    return render(request,'zudipay/fadakpage.html',args)

this is fadakpage.html / template (it shows empty):

{% for i in range %}
      {{tours.i.tourleader}}
{% endfor %}

but if i change {{tours.i.tourleader}} to {{tours.0.tourleader}} it works!! I also checked I values and it was true !!

Do you require the index in your loop? If not, then Daniel Roseman's answer is all you need — Daniel Holmes

Not sure if this is exactly what you need. You can get the loop counter by using {{ forloop.counter }} to get the loop index starting at 1, or {{ forloop.counter0 }} to get the index starting at 0.

{% for tour in tours %}
      {{ tour.tourleader }} {{ forloop.counter }}
{% endfor %}

See the docs for more info.

No, indeed, that does not work in a Django template. But there is no reason to do it: just loop through tours.

{% for tour in tours %}
      {{tour.tourleader}}
{% endfor %}

You change your view to this:

def fadakpage(request):
    j = 0
    tours = []
    for i in tour.objects.order_by('tourleader'):
        tours.append((i, j))
        j += 1
    args = {'tours': tours, 'range': range(j)}
    return render(request, 'zudipay/fadakpage.html', args)

And use list of tuples in your template:

{% for tour in tours %}
  {{ tour.0.tourleader }}
{% endfor %}

In this code in your template {{ tour.0 }} is tour object and {{ tour.1 }} is count.
