Django pagination - example from documentation. How to display with all sites number? - django

Question

This is example from documentation Django:
def listing(request):
contact_list = Contacts.objects.all()
paginator = Paginator(contact_list, 25) # Show 25 contacts per page
page = request.GET.get('page')
try:
contacts = paginator.page(page)
except PageNotAnInteger:
# If page is not an integer, deliver first page.
contacts = paginator.page(1)
except EmptyPage:
# If page is out of range (e.g. 9999), deliver last page of results.
contacts = paginator.page(paginator.num_pages)
return render_to_response('list.html', {"contacts": contacts})
template:
{% for contact in contacts %}
{# Each "contact" is a Contact model object. #}
{{ contact.full_name|upper }}<br />
...
{% endfor %}
<div class="pagination">
<span class="step-links">
{% if contacts.has_previous %}
previous
{% endif %}
<span class="current">
Page {{ contacts.number }} of {{ contacts.paginator.num_pages }}.
</span>
{% if contacts.has_next %}
next
{% endif %}
</span>
</div>
This display for example:
Page 2 of 3. next
How to display it in this way:
previous 1 <b>2</b> 3 Next
Current page with html <b> mark.
?

Answer 1

You can try this:
{% for num in contacts.paginator.page_range %}
{% ifequal num contacts.number %}
<span class="current"><b>{{ num }}</b></span>
{% else %}
{{ num }}
{% endifequal %}
{% endfor %}

Answer 2

Below example is actually for class based views but would work fine.
CSS is Twitter Bootstrap V3.0.0.
{% if is_paginated %}
<ul class="pagination">
{% if page_obj.has_previous %}
<li>«</li>
{% else %}
<li class="disabled">«</li>
{% endif %}
{% for num in page_obj.paginator.page_range %}
{% ifequal num page_obj.number %}
<li class="active">{{ num }}<span class="sr-only">(current)</span></li>
{% else %}
<li>{{ num }}</li>
{% endifequal %}
{% endfor %}
{% if page_obj.has_next %}
<li>»</li>
{% else %}
<li class="disabled">»</li>
{% endif %}
</ul>
{% endif %}

Answer 3

This is mine.
{% if page.paginator.num_pages > 1 %}
<nav aria-label="Page navigation">
<ul class="pagination justify-content-center">
{% if page.paginator.num_pages != 1 %}
<li class="page-item"><a class="page-link" href="?page=1">First</a></li>
{% else %}
<li class="page-item disabled"><a class="page-link" href="#">First</a></li>
{% endif %}
{% if page.has_previous %}
<li class="page-item"><a class="page-link" href="?page={{ page.previous_page_number }}">«</a></li>
{% else %}
<li class="page-item disabled"><a class="page-link" href="#">«</a></li>
{% endif %}
{% for i in page.paginator.page_range %}
{% if page.number == i %}
<li class="page-item active"><a class="page-link" href="#">{{ i }} <span class="sr-only">(current)</span></a></li>
{% elif page.number > i|add:"-5" and page.number < i|add:"+5"%}
<li class="page-item"><a class="page-link" href="?page={{ i }}">{{ i }}</a></li>
{% endif %}
{% endfor %}
{% if page.has_next %}
<li class="page-item"><a class="page-link" href="?page={{ page.next_page_number }}">»</a></li>
{% else %}
<li class="page-item disabled"><a class="page-link" href="#">»</a></li>
{% endif %}
{% if page.paginator.num_pages != page.number %}
<li class="page-item"><a class="page-link" href="?page={{ page.paginator.num_pages }}">Last</a></li>
{% else %}
<li class="page-item disabled"><a class="page-link" href="#">Last</a></li>
{% endif %}
</ul>
</nav>
{% endif %}

Answer 4

If someone needs Bootstap 4 Alpha 5 version of code.
Also I did two changes:
I do not like duplicates of pages, so I changed in my case /profiles/?page=1 to simple /profiles/.
I have lots of pages, so I do not show all pages. I show just: The 1st, the last, current and +-3 pages from the current one, and every 10th page.
If you need just all pages with Bootstrap 4 without my modifications, just remove unnecessary parts of code (everything is commented).
{% if is_paginated %}
<nav aria-label="Page navigation">
<ul class="pagination">
<!-- << PREVIOUS PART -->
<!-- << Disable 'Previous' page button if you are at the 1st page -->
{% if not page_obj.has_previous %}
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1" aria-label="Previous">
<!-- << If you are at the 2nd page,
'Previous' page button will get '/profiles/' url instead of '/profiles/?page=1' -->
{% elif page_obj.previous_page_number == 1 %}
<li class="page-item">
<a class="page-link" href="{{ profiles_1st_page_url }}" aria-label="Previous">
{% else %}
<li class="page-item">
<a class="page-link" href="?page={{ page_obj.previous_page_number }}" aria-label="Previous">
{% endif %}
<span aria-hidden="true">«</span>
<span class="sr-only">Previous</span>
</a>
</li>
<!-- PAGES PART -->
{% for num in page_obj.paginator.page_range %}
<!-- Active page -->
{% if num == page_obj.number %}
<li class="page-item active">
<a class="page-link" href="#">{{ num }}<span class="sr-only">(current)</span></a>
</li>
{% else %}
<li class="page-item">
<!-- For the 1st page we do not use ?page=1 -->
{% if num == 1 %}
<a class="page-link" href="{{ profiles_1st_page_url }}">{{ num }}</a>
{% else %}
<!-- Show current page and +-3 pages -->
{% if num|add:"-3" <= page_obj.number and page_obj.number <= num|add:"3" %}
<a class="page-link" href="?page={{ num }}">{{ num }}</a>
<!-- Shows every 10th page and the last page -->
{% elif num|divisibleby:"10" or num == page_obj.paginator.num_pages %}
<a class="page-link" href="?page={{ num }}">{{ num }}</a>
{% endif %}
{% endif %}
</li>
{% endif %}
{% endfor %}
<!-- >> NEXT PART -->
{% if not page_obj.has_next %}
<!-- << Disable 'Next' page button if you are at the last page -->
<li class="page-item disabled">
<a class="page-link" href="#" tabindex="-1" aria-label="Next">
{% else %}
<li class="page-item">
<a class="page-link" href="?page={{ page_obj.next_page_number }}" aria-label="Next">
{% endif %}
<span aria-hidden="true">»</span>
<span class="sr-only">Next</span>
</a>
</li>
</ul>
</nav>
{% endif %}
And it looks like:
