That page contains no results Django ListView - django

I have the problem in Django 1.9
I have this problem when I go to the last result pagination
views.py
class UserList(ListView):
model = User
template_name = 'account/users.html'
paginate_by = 1
users.html
<div class="pagination">
<span class="page-links">
{% if page_obj.has_previous %}
previous
{% endif %}
<span class="page-current">
Page {{ page_obj.number }} of {{ page_obj.paginator.num_pages }}.
</span>
{% if page_obj.has_next %}
next
{% endif %}
</span>

I've encountered this as well and the problem is that Paginator.page_range is 1-based.
https://docs.djangoproject.com/en/1.9/topics/pagination/#django.core.paginator.Paginator.page_range
I've used the following solution: (I'm using Foundation 6)
{% if is_paginated %}
<ul class="pagination text-center" role="navigation" aria-label="Pagination">
{% if page_obj.has_previous %}
<li class="pagination-previous">
<a href="?page={{ page_obj.previous_page_number }}">
<span>Previous</span>
</a>
</li>
{% else %}
<li class="pagination-previous disabled">
<span>Previous</span>
</li>
{% endif %}
{% for page in paginator.page_range %}
{% if paginator.num_pages != page %}
<li class="{% if page == page_obj.number %}active{% endif %}">
{{ page }}
</li>
{% endif %}
{% endfor %}
{% if page_obj.has_next and paginator.num_pages != page_obj.next_page_number %}
<li class="pagination-next">
<a href="?page={{ page_obj.next_page_number }}">
<span>Next</span>
</a>
</li>
{% else %}
<li class="pagination-next disabled">
<span>Next</span>
</li>
{% endif %}
</ul>
{% endif %}
Hope this helps! I initially based my code from https://ana-balica.github.io/2015/01/29/pagination-in-django/

Django template large data pagination link issue

I am using the django paginator in my template. Its working ok with less data, but not working good when there's large numbers of pages.
Pagination links code is given bellow:

{% if request.GET.search %}&search={{ request.GET.search }}
{% endif %}" class="page-link"><i class="fas fa-angle-double-left"></i></a>
</li>
{% endif %}
{% for j in match_list.paginator.page_range %}
{% if match_list.number == j %}
<li class="active"><a class="page-link" href="#">{{ j }}</a></li>
{% else %}
<li><a href="?p={{ j }}{% if request.GET.search %}&search={{ request.GET.search }}

Exclude a type of post from pagination

I use a model for the posts of my blog that you can see here(Is a my old post).
As you can see, in that moldel, I've an option to indicate highlighted post. If I use the code below to implement the pagination on my blog, also the highlighted post is sent in a page different from the first.
{% for post in posts %}
{% if post.highlighted == 1 %}
<h1><strong>Highlighted</strong></h1>
<img src="{{ post.header_image }}" alt="Image of {{ post.title }}">
<h1>{{ post.title }}</h1>
<h4>{{ post.tagline }}</h4>
{% endif %}
{% endfor %}
<hr><hr><hr>
{% for post in posts %}
{% if post.highlighted == 0 %}
<h1><strong>Not Highlighted</strong></h1>
<img src="{{ post.header_image }}" alt="Image of {{ post.title }}">
<h1>{{ post.title }}</h1>
<p>{{ post.tagline }}</p>
<h5>{{ post.publishing_date|date }}</h5>
{% for keyconcepts in post.keyconcepts.all %}
#{{ keyconcepts }}
{% endfor %}
<hr>
{% endif %}
{% endfor %}
{% block pagination %}
{% if is_paginated %}
<div class="pagination px-auto">
<nav aria-label="Page navigation">
<ul class="pagination justify-content-center">
{% if page_obj.has_previous %}
<li class="page-item">
<a class="page-link text-center shadow" href="{{ request.path }}?page={{ page_obj.previous_page_number }}">Pagina precedente</a>
</li>
{% endif %}
<li class="page-item disabled">
<p class="page-link text-center shadow">Pagina {{ page_obj.number }} di {{ page_obj.paginator.num_pages }}.</p>
</li>
{% if page_obj.has_next %}
<li class="page-item">
<a class="page-link text-center shadow" href="{{ request.path }}?page={{ page_obj.next_page_number }}">Pagina successiva</a>
</li>
{% endif %}
</ul>
</nav>
</div>
{% endif %}
{% endblock %}
I would like to exclude all highlighted post from the pagination. Is it possible?
Below views.py
class ListPost(ListView):
model = Blog
context_object_name = 'posts'
queryset = Blog.objects.filter(category="G.I.S.") #FUNDAMENTAL FILTER
template_name = "blog/list_post.html"
paginate_by = 3
class ListPost(ListView):
queryset = Blog.objects.filter(is_highlighted=True)
context_object_name = 'posts'
template_name = "blog/list_post.html"
paginate_by = 3
Note Blog seems a misnomer. BlogPost seems more accurate.

How to use django paginator page range for displaying the first 10 numbers not all?

I want to change the blow script to show just the first 10 page numbers. Now it shows all page numbers. Could you please tell me how to change it? I tried several ways but it didn't work. Any help will be appreciated!
{% if forloop.counter|divisibleby:"3" or forloop.last %}
</div>
{% endif %}
{% endfor %}
{% if is_paginated %}
<div class="row">
<ul class="pagination pagination-md ">

Listing Tags of a Post in Django CMS and Aldryn NewsBlog

I am trying to figure out how to display tags belonging to an article created within Aldryn NewsBlog plugin. Unfortunately, I cannot find any documentation on how do it.
I was able to display categories using the following code.
<span style="margin: 0; display: block">
<h4 style="display:inline-flex">Categories:</h4>
{% for category in article.categories.all %}
{{ category.name }} {% if not forloop.last %}, {% endif %}
{% endfor %}
</span>
For tags, I am using this code:
<span style="margin: 0; padding-bottom: 0; display: block">
<h4 style="display:inline-flex">Tags:</h4>
{% for tag in article.tag %}
{{ tag.name }} {% if not forloop.last %}, {% endif %}
{% endfor %}
</span>
What am I doing wrong? Could anyone tell me how to display tags?
this is the official tags template of aldryn-newsblog, it worked for me:
{% load i18n apphooks_config_tags %}
<div class="aldryn aldryn-newsblog aldryn-newsblog-tags">
<ul class="list-unstyled">
<li{% if not newsblog_tag %} class="active"{% endif %}>
{% trans "All" %}
</li>
{% for tag in tags %}
<li{% if newsblog_tag.id == tag.id %} class="active"{% endif %}>
<a href="{% namespace_url "article-list-by-tag" tag.slug namespace=instance.app_config.namespace default='' %}">
{{ tag.name }}
<span class="badge">{{ tag.article_count }}</span>
</a>
</li>
{% endfor %}
</ul>
https://github.com/aldryn/aldryn-newsblog/blob/master/aldryn_newsblog/boilerplates/bootstrap3/templates/aldryn_newsblog/plugins/tags.html
you're right, that is what you're looking for, with article.tags.all:
{% if article.tags.exists %}
<ul style="margin-left: 0">
{% for tag in article.tags.all %}
<li class="tags">{{ tag.name }}</li>
{% if not forloop.last %}<span class="separator tags-separator">|</span> {% endif %}
{% endfor %}
</ul>
{% endif %}

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

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.
?
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 %}
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 %}
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 %}
Looks like
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:
