I’m using HTMX to load partial pages for a table in my Django project, but I’m facing problems with pagination. The paging may not advance properly (it shows 2 pages, e.g. <Page 1 of 2>), may stream rows endlessly, or the paging UI might not appear at all. I’ve tried several fixes without success.
My setup is as follows:
The following code snippets outline the components of my setup:
HTML<div class="container-fluid rounded border" style="max-width:1100px; height:510px"> <div class="row"> <div class="col"> <div id="task_indx" hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}' hx-trigger="load" hx-get="{% url 'console_app:console_view' %}" hx-target="this"> </div> </div> </div> </div>
PYTHONdef console_view(request): if request.htmx: template = 'console_app/task_index.html' return render(request, template, {}) else: data = [] fls_msg_cnt = ManagerMessages.objects.filter().count() nodes_cnt = Nodes.objects.filter().count() ToLog_cnt = ToLog.objects.filter().count() data = { 'labels': ['Messages', 'Ivanti', 'SolarWinds', 'Control-M', 'TurnOver Log'], 'values': [fls_msg_cnt, nodes_cnt, 28, 21, ToLog_cnt] } template = 'console_app/base_console_ap.html' return render(request, template, {'chart_data': data})
PYTHONdef task_index(request): if request.htmx: print('htmx - task_index') tasks = Task.objects.all().order_by(_TASK_ORDBY) paginator = Paginator(tasks, 4) page_number = request.GET.get('page') try: page_obj = paginator.page(page_number) except PageNotAnInteger: page_obj = paginator.page(1) except EmptyPage: page_obj = paginator.page(paginator.num_pages) template = 'console_app/task_row.html' return render(request, template, {'page_obj': page_obj, 'count': tasks.count()})
HTML<div id="taskList"> {% include 'console_app/task_list.html' %} </div>
HTML<tbody id="taskrows" hx-trigger="load" hx-get="{% url 'console_app:task_index' %}" hx-target="this"> <tr> <td class="spinner-border" role="status"> <span class="visually-hidden">Loading please wait...</span> </td> </tr> </tbody>
HTML{% for task in page_obj %} <tr> {% if task.completed %} <td style="word-wrap: break-word;min-width: 160px;max-width: 260px;"><s>{{ task.task }}</s></td> {% else %} <td style="word-wrap: break-word;min-width: 160px;max-width: 260px;">{{ task.task }}</td> {% endif %} <td>{{ task.created_on }}</td> <td>{{ task.notes }}</td> <td> {% if task.completed %} <button type="button" class="btn-sm btn btn-outline-secondary" disabled>✓</button> {% else %} <button type="button" class="btn-sm btn btn-outline-success" hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}' hx-get="{% url 'console_app:mark_task' task.pk %}" hx-target="#taskList" style="cursor: pointer;">✔</button> {% endif %} <button type="button" class="btn-sm btn btn-outline-danger" hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}' hx-get="{% url 'console_app:delete_task' task.pk %}" hx-target="#taskList" hx-confirm="Are you sure you wish to delete?" style="cursor: pointer;">DEL</button> <button type="button" class="btn-sm btn btn-outline-warning" hx-headers='{"X-CSRFToken": "{{ csrf_token }}"}' hx-get="{% url 'console_app:edit_task' task.pk %}" hx-target="closest tr" hx-swap="outerHTML" style="cursor: pointer;">Edit</button> </td> </tr> {% endfor %} <div class="btn-group" role="group" aria-label="Item pagination"> {% if page_obj.has_previous %} <a href="?page={{ page_obj.previous_page_number }}" class="btn btn-outline-primary">«</a> {% endif %} {% for page_number in page_obj.paginator.page_range %} {% if page_obj.number == page_number %} <button class="btn-sm btn btn btn-primary active"> <span>{{ page_number }} <span class="sr-only">(current)</span></span> </button> {% else %} <a href="?page={{ page_number }}" class="btn btn-outline-primary">{{ page_number }}</a> {% endif %} {% endfor %} {% if page_obj.has_next %} <a href="?page={{ page_obj.next_page_number }}" class="btn btn-outline-primary">»</a> {% endif %} </div> <div>Total record count: {{ count }}</div>
I also included an image reference which shows the pagination UI, but the behavior remains inconsistent. Any advice or insights into what might be causing these HTMX pagination issues would be greatly appreciated.

I can see several issues with your HTMX pagination implementation that are likely causing the inconsistent behavior you're experiencing.
Your pagination links need to use HTMX attributes to properly trigger AJAX requests. Currently, they're using standard href
attributes which cause full page reloads:
HTML<!-- Change this: --> <a href="?page={{ page_obj.previous_page_number }}" class="btn btn-outline-primary">«</a> <!-- To this: --> <a hx-get="{% url 'console_app:task_index' %}?page={{ page_obj.previous_page_number }}" hx-target="#taskrows" class="btn btn-outline-primary">«</a>
Apply this change to all pagination links, including the page numbers and next button.
Your current structure is overly complex with multiple nested HTMX requests:
base_console_ap.html → console_view → task_index.html → task_list.html → task_index view → task_row.html
Simplify this to reduce potential conflicts:
PYTHONdef task_index(request): if request.htmx: tasks = Task.objects.all().order_by(_TASK_ORDBY) paginator = Paginator(tasks, 4) page_number = request.GET.get('page') try: page_obj = paginator.page(page_number) except PageNotAnInteger: page_obj = paginator.page(1) except EmptyPage: page_obj = paginator.page(paginator.num_pages) # Return the entire table content including pagination template = 'console_app/task_list_with_pagination.html' return render(request, template, {'page_obj': page_obj, 'count': tasks.count()})
Create a new template task_list_with_pagination.html
that includes both the table rows and pagination controls:
HTML{% for task in page_obj %} <tr> <!-- Your existing row content --> </tr> {% endfor %} <!-- Pagination controls at the bottom of the table --> <tr> <td colspan="4"> <div class="btn-group" role="group" aria-label="Item pagination"> {% if page_obj.has_previous %} <a hx-get="{% url 'console_app:task_index' %}?page={{ page_obj.previous_page_number }}" hx-target="#taskrows" class="btn btn-outline-primary">«</a> {% endif %} {% for page_number in page_obj.paginator.page_range %} {% if page_obj.number == page_number %} <button class="btn-sm btn btn-primary active"> <span>{{ page_number }} <span class="sr-only">(current)</span></span> </button> {% else %} <a hx-get="{% url 'console_app:task_index' %}?page={{ page_number }}" hx-target="#taskrows" class="btn btn-outline-primary">{{ page_number }}</a> {% endif %} {% endfor %} {% if page_obj.has_next %} <a hx-get="{% url 'console_app:task_index' %}?page={{ page_obj.next_page_number }}" hx-target="#taskrows" class="btn btn-outline-primary">»</a> {% endif %} </div> <div>Total record count: {{ count }}</div> </td> </tr>
Modify your table structure to properly handle the HTMX response:
HTML<table class="table"> <thead> <!-- Your table headers --> </thead> <tbody id="taskrows" hx-trigger="load" hx-get="{% url 'console_app:task_index' %}" hx-target="this"> <tr> <td class="spinner-border" role="status"> <span class="visually-hidden">Loading please wait...</span> </td> </tr> </tbody> </table>
console.log
statements in your JavaScript to track HTMX requests and responseshtmx:beforeRequest
and htmx:afterRequest
to debugBy implementing these changes, your pagination should work correctly with HTMX, maintaining the table state while only updating the necessary parts of the page.
