I have 2 lists (if that is what django calls them) containg an id and a key/value pair e.g. [{'id': x, 'string': 'string'}] one list assigned to variable 'periods' the other assigned to 'paydates'.

I am trying to loop through each list and display the value from each in an HTML element, using DTL.

I have the DTL in the HTML page {% for ... in ... %} one inside the other. The outer for loop from list 'periods' is working correctly, the inner for loop from list 'paydates' is not displaying anything at all, it doesn't throw an error either.

The blue date in the pic is from the 'periods' list and is working correctly, the date from the 'paydates' list is supposed to show underneath 'Pay Date'.

I cannot separate the for loop code because of the way i want my html page displayed. I am not sure what options I have to rectify the issue.

My code follows:

home.html:

    {% load static %}

    <meta name="viewport" content="width=device-width, initial-scale=1.0" />

    <link rel="stylesheet" href="{% static 'appmain/style.css' %}" />
    <title>Payslip Data</title>
  </head>
  <body>

I don't know if the 2 lists can be combined and the relevant data extracted and placed in the correct element, I am new to django and programming in general. Hopefully it is a simple solution.

My thanks in advance.

Reset to default 0

the problem is that you're only passing one of the lists (periods or paydates) to the template at a time because in your urls.py the second path('', views.dates) overwrites the first one (views.main).

So when Django renders home.html, only paydates or periods is available, not both.

try this code

views.py
    from django.shortcuts import render
from django.http import HttpRequest
from django.http import HttpResponse

periods = [
  {'id': 0, 'period': '15/06/2025'},
  {'id': 1, 'period': '29/06/2025'},
  {'id': 2, 'period': '13/07/2025'},
  {'id': 3, 'period': '27/07/2025'},
  {'id': 4, 'period': '10/08/2025'},
  {'id': 5, 'period': '24/08/2025'},
  {'id': 6, 'period': '07/09/2025'},
  {'id': 7, 'period': '21/09/2025'},
  {'id': 8, 'period': '05/10/2025'},
  {'id': 9, 'period': '19/10/2025'},
  {'id': 10, 'period': '02/11/2025'},
  {'id': 11, 'period': '16/11/2025'},
  {'id': 12, 'period': '30/11/2025'},
  {'id': 13, 'period': '14/12/2025'},
  {'id': 14, 'period': '28/12/2025'},
  {'id': 15, 'period': '11/01/2026'},
  {'id': 16, 'period': '25/01/2026'},
  {'id': 17, 'period': '08/02/2026'},
  {'id': 18, 'period': '22/02/2026'},
  {'id': 19, 'period': '08/03/2026'},
  {'id': 20, 'period': '22/03/2026'},
  {'id': 21, 'period': '05/04/2026'},
  {'id': 22, 'period': '19/04/2026'},
  {'id': 23, 'period': '03/05/2026'},
  {'id': 24, 'period': '17/05/2026'},
  {'id': 25, 'period': '31/05/2026'},
  {'id': 26, 'period': '14/06/2026'}
]

paydates = [
  {'id': 0, 'paydate': '02/07/2026'},
  {'id': 1, 'paydate': '02/07/2026'},
  {'id': 2, 'paydate': '02/07/2026'},
  {'id': 3, 'paydate': '02/07/2026'},
  {'id': 4, 'paydate': '02/07/2026'},
  {'id': 5, 'paydate': '02/07/2026'},
  {'id': 6, 'paydate': '02/07/2026'},
  {'id': 7, 'paydate': '02/07/2026'},
  {'id': 8, 'paydate': '02/07/2026'},
  {'id': 9, 'paydate': '02/07/2026'},
  {'id': 10, 'paydate': '02/07/2026'},
  {'id': 11, 'paydate': '02/07/2026'},
  {'id': 12, 'paydate': '02/07/2026'},
  {'id': 13, 'paydate': '02/07/2026'},
  {'id': 14, 'paydate': '02/07/2026'},
  {'id': 15, 'paydate': '02/07/2026'},
  {'id': 16, 'paydate': '02/07/2026'},
  {'id': 17, 'paydate': '02/07/2026'},
  {'id': 18, 'paydate': '02/07/2026'},
  {'id': 19, 'paydate': '02/07/2026'},
  {'id': 20, 'paydate': '02/07/2026'},
  {'id': 21, 'paydate': '02/07/2026'},
  {'id': 22, 'paydate': '02/07/2026'},
  {'id': 23, 'paydate': '02/07/2026'},
  {'id': 24, 'paydate': '02/07/2026'},
  {'id': 26, 'paydate': '02/07/2026'}
]


def main(request):
    return render(request, 'appmain/home.html', {'periods': periods, 'paydates': paydates})
url.py
from django.urls import path
from . import views

urlpatterns = [
    path('', views.main),
]

now both periods and paydates will be available in the template, and the {% for paydate in paydates %} loop will actually have data to iterate over.
