How to access array elements in a Django template?

Question

I am getting an array arr passed to my Django template. I want to access individual elements of the array in the array (e.g. arr[0], arr[1]) etc. instead of looping through the whole array.

Is there a way to do that in a Django template?

You can access item like this `arr.0`, `arr.1`, ... Another solution : write your own template tag `arr|array_item: "0" ` or something like this. — rphonika, Jul 30 '14 at 18:41

Remember that the dot notation in a Django template is used for four different notations in Python. In a template, foo.bar can mean any of:

foo[bar]       # dictionary lookup
foo.bar        # attribute lookup
foo.bar()      # method call
foo[bar]       # list-index lookup

It tries them in this order until it finds a match. So foo.3 will get you your list index because your object isn't a dict with 3 as a key, doesn't have an attribute named 3, and doesn't have a method named 3.

Aren't the first and last more like`foo['bar']`? – Bob Stein Feb 10 '16 at 05:18

There seems to be no way to access a list item using a variable index :( – Vicky Chijwani Jan 27 '17 at 16:45

Agree with @VickyChijwani: the fourth option above is not valid. Django templates don't seem to do list-index lookups with variables – ehacinom Feb 09 '17 at 17:46

Is there any way to do this without magic numbers? In other words to "name" the .0 .1 .2 etc...? Such as array["first name"], array["last name"] etc.. – jhagege Dec 19 '14 at 09:16
@cyberjoac in that case use a dict. In the view: d = {'first_name':'foo', 'last_name': 'bar'}. In the template {{ d.first_name }} will work just fine. – Ofri Raviv Dec 19 '14 at 10:49

You can access sequence elements with arr.0, arr.1 and so on. See The Django template system chapter of the django book for more information.

When you render a request to context some information, for example:

return render(request, 'path to template', {'username' :username, 'email' :email})

You can access to it on template, for variables

{% if username %}{{ username }}{% endif %}

for arrays

{% if username %}{{ username.1 }}{% endif %}
{% if username %}{{ username.2 }}{% endif %}

you can also name array objects in views.py and then use it as shown below:

{% if username %}{{ username.first }}{% endif %}
