I am using Django pagination - and it works great ;) ...
But in some cases I have a URL with queryies - and when i use the default template setup for pagination - it wont work..
<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>
How can I do it ? ..
My url can look like this:
http://www.example.com/tag/?tag=fewa&met=23&g=2&page=2
or
http://www.example.com/tag/?tag=fewa&g=2&t=ewq&page=2
What can I do at the pre and next position?
forrige
I got IT ;)

I want to add simple back/next pagination in my item detail view.
How can I do that ?
I have something like that in my template:
{% if is_paginated %}
<div class="pagination">
<span class="page-links">
{% if page_obj.has_previous %}
Back
{% endif %}
{% if page_obj.has_next %}
Next: {{ item.title }}
{% endif %}
</span>
</div>
{% endif %}
The main thing is that I want to do this in ItemDetailView, not in ItemListView, because in list view I have all items, and I just want to go between items in detail view.
Thanks a lot for help.
I'm building a simple blog app using Django.
This app has a main template blog.html which is shared between the following views:
blog (url: /blog/[page number])
Main page of the blog, displays the last articles
search (url: /search/<query>/[page number])
Will display the articles who match the query
category (url: /category/<category name>/[page number])
Will display the articles from the given category
Each a this views provides the template blog.html with an object page obtained using the function Paginator each time with a different objects list (depending on the view).
Here is my problem:
The template blog.html contains a pager
<ul class="pager">
{% if page.has_previous %}
<li class="previous">
<a href="{{ url_previous_page }}" class="btn btn-primary" >← Older</a>
</li>
{% endif %}
{% if page.has_next %}
<li class="next">
<a href="{{ url_next_page }}" class="btn btn-primary" >Newer →</a>
</li>
{% endif %}
</ul>
How can I define in an elegant way the values of url_next_page and url_previous_page in all the views?
You shouldn't really need to supply the links for the next and previous buttons like that. I would suggest changing your pagination code to be something like this:
<div class="pagination-wrap">
<span class="pagination-links">
{% if page_obj.has_previous %}
{% endif %}
<span class="current">
{{ page_obj.number }} of {{ page_obj.paginator.num_pages }}
</span>
{% if page_obj.has_next %}
{% endif %}
</span>
<div>{{ page_obj.start_index }} to {{ page_obj.end_index }} of {{ page_obj.paginator.count }}</div>
</div>
In your views, all you need to specify is the number of objects to paginate by with paginate_by = 15.
If you really want to, you could create a mixin for your list views to use which has a method that could return the url you want.
I get the following error when serving my django application using Nginx+FastCGI
Invalid block tag: 'add_pinned_status', expected 'else' or 'endif'
Oddly, the site works just fine when I'm serving using the Django development server. It also works with Nginx most of the time, but the error randomly appears and reappears with refreshes. Any idea what the problem could be?
EDIT: Here's the code, just to clarify that there's NO hanging if statement.
{% extends 'master.html'%}
{% load thumbnail %}
{% load tags %}
{% block 'title' %}
{{ title }}
{% endblock %}
{% block 'content' %}
<div id="feed" class="content">
{% for book in books.object_list %}
<div class="book_preview">
<div class="thumbnail">
<a href="/book/{{ book.id }}/{{ book.get_slug }}/">
{% if book.cover_image %}
{% thumbnail book.cover_image "120" as im %}
<img src="{{ im.url }}" alt="Python for Software Design"/>
{% endthumbnail %}
{% else %}
<img src="{{ STATIC_URL }}default_thumb.jpg" alt="Python for Software Design"/>
{% endif %}
</a>
</div>
<div class="book_details">
<h2 class="book_title">
<a class="book_profile_link" href="/book/{{ book.id }}/{{ book.get_slug }}/">{{ book.title }}</a>
{% if user != book.uploader %}
<a class="shelf_adder {% add_pinned_status request book.pk %}" href="/shelf/{{ book.id }}/toggle/?next={{ request.get_full_path }}" title="Toggle shelf status"></a>
{% endif %}
</h2>
<h3 class="book_subtitle">
{% if book.subtitle %}
{{ book.subtitle }}
{% else %}
<a href='/book/{{book.id}}/edit/#subtitle'>Provide subtitle</a>
{% endif %}
</h3>
<h3 class="book_authors"> by {{ book.author.filter|join:", " }}</h3>
<div class="book_description">
{% if book.description %}
<p>
{{ book.description|truncatewords:25 }}
</p>
{% else %}
<p class="message">No description available. Create one.</p>
{% endif %}
</div>
<div class="book_links">
<a href="/book/{{ book.id }}/{{ book.get_slug }}/" class="book_profile_link" title="Book profile">
Book profile
</a>
<a href="http://{{ book.homepage }}" class="book_website_link" title="Book website" target="_blank">
Book website
</a>
</div>
<p>Points: {{ book.shelf_additions }}</p>
<div class="book_tags">
{% if book.topics.all %}
{% for topic in book.topics.filter %}
{{ topic }}
{% endfor %}
{% else %}
<a href="/book/{{ book.id }}/edit/#topics" title='Click to add'>no topics added☹</a>
{% endif %}
</div>
</div>
<div style="clear: both;"></div>
</div>
{% endfor %}
<div class="pagination">
{% if books.has_previous %}
previous
{% endif %}
<span class="current">
Page {{ books.number }} of {{ books.paginator.num_pages }}
</span>
{% if books.has_next %}
next
{% endif %}
</div>
</div>
{% endblock %}
The problem starts on the line after the if user != book.uploader statement, which as you can see is terminated with the appropriate endif. I suspect it may be some sort of timeout but I'm not entirely sure. Keep in mind, it works sometimes but randomly stops when using Nginx. It works flawlessly with the dev server.
Django gives that error when you have an unclosed templatetag. In this case an {% if ... %} templatetag.
As to why it only happens in certain scenarios, it might be inside a conditional tag itself, so it's not always processed, but I think Django processes the whole template despite what's going on conditionally or not. It might also be possible that there was some mistake in updating your production site and it's using a different/older version than your development site.
Regardless, the error is the error. Find the unclosed templatetag, and you'll solve it across the board.
UPDATE: The alternative is that the add_pinned_sites templatetag is undefined. Assuming it is in fact loaded in {% load tags %}, make sure that that templatetag library is available in all running environments, i.e. it literally exists on the server. If it is in fact there, make sure you completely reload your Nginx+FastCGI environment, or just reboot the server to be completely sure.
Is "tags" the actual name of the tag library that holds add_pinned_sites? Might be worth changing it to a clearer name-- just wondering if it's possible you're seeing import collisions between that and another tag library (like Django's built-in tags).
Hey I have been plugging away trying to get haystack working with whoosh to implement a search backend for a django cms project i have been working on. After figuring out some really weird permissions errors i can almost taste sucess.
I now have haystack creating the indexes correctly and it will even display results for a custom app i have created an index for however i cannot get it to display any results for the cms page stuff. There are results being returned as im not getting the "No Results" message but nothing is being printed out in the results.html template.
bearing in mind that im letting django-cms-search handle the indexing for the cms app i didnt think i would need to add anything extra to get the results to display.
So to outline what i have so far
Haystack installed with a Whoosh backend
my setting.py setting are
HAYSTACK_SITECONF = 'lactoseintolerant.lactose_search.search_sites'
HAYSTACK_SEARCH_ENGINE = 'whoosh'
HAYSTACK_WHOOSH_PATH = '/home/mike/sites/lactosetoloerant/lactoseintolerant/whoosh'
HAYSTACK_SEARCH_RESULTS_PER_PAGE = 50
my search_sites.ph file looks like
import haystack
from cms.models import monkeypatch_reverse
from cms.plugin_pool import plugin_pool
monkeypatch_reverse()
haystack.autodiscover()
i have a custom index for my Topics Model that looks like so (This is working and resturning Reuslts)
from topics.models import Topic
from haystack.indexes import *
from haystack import site
class TopicIndex(SearchIndex):
text = CharField(document=True, use_template=True)
def index_queryset(self):
"""
This is used when the entire index for model is updated, and should only include
public entries
"""
return Topic.objects.filter(active=True)
site.register(Topic, TopicIndex)
My results.html template look like
{% extends "base.html" %}
{% load cache cms_tags menu_tags %}
{% block base_content %}
<div id="panel-left">
{% block nav %}
<ul id="nav-left">
{% show_menu 1 100 100 100 %}
</ul> <!-- #nav-left -->
{% endblock %}
{% block panel_left %}
{% endblock %}
</div>
{% block panel_right %}
<div id="panel-main">
{% ifequal q '' %}
<h1 id="page-head-2">Search Results Page</h1>
<p>Please provide search criteria or keywords</p>
<br />
<form action=".">
<p>
<input type="text" name="q" value="{{ q }}">
<input type="submit" name="search" value="Search">
</p>
</form>
{% else %}
<h1 id="page-head-2">Search Results - page {{ request.GET.page|default:1 }} of {{ paginator.num_pages }}</h1>
<h1 id="page-head-2">Found {{ paginator.count }} for <span id="searchString">'{{ q }}'</span></h1>
<form action=".">
<p>
<input type="text" name="q" value="{{ q }}">
<input type="submit" name="search" value="Search">
</p>
</form>
<ul id="searchResults">
{% for item in current_page.object_list %}
<li class="searchResult">
<h2 class="searchTitle">{{ forloop.counter }}. {{ item.get_title }}</h2>
<a class="searchLink" href="{{ item.get_absolute_url }}">{{ item.get_absolute_url }}</a>
</li> <!-- .searchResult -->
{% endfor %}
</ul>
{% if paginator.num_pages > 1 %}
<div id="pagination">
{% for page_range_item in paginator.page_range %}
{% if not request.GET.page and page_range_item == 1 or request.GET.page == page_range_item|safe %}
<span class="pag-link current" href="/topics/?page={{ page_range_item }}">{{ page_range_item }}</span>
{% else %}
<a class="pag-link" href="/search/?q={{ q }}&page={{ page_range_item }}">{{ page_range_item }}</a>
{% endif %}
{% endfor %}
</div>
{% endif %}
{% endifequal %}
</div>
{% endblock %}
{% endblock %}
Im clearly missing something obvious here any help would be grealt appreciated!!
Cheers
i think you got it almost, try to change {{ item.get_absolute_url }} to {{ item.object.get_absolute_url }} inn your results.html file.
is there any existing pagination solution for Django contrib.comments?
What I need is just a simple paginated django comments, for the Basic Blog application (from the Django Basic Apps) I used, using a simple has_previous and has_next
I have copied the django.contrib.comments and tried modify the code but with no success. The code is pretty hard to understand (django/contrib/comments/templatetags/comments.py) because it consists of Node and Parser
here is my comments.html template I used for the Blog application:
{% load comments markup %}
{% get_comment_list for object as comment_list %}
{% if comment_list %}
<div class="comments g_7 left">
<a name="comments"></a>
<div class="subtitle">Comments</div>
{% for comment in comment_list %}
{% if comment.is_public %}
<div class="comment g_6" id="c{{ comment.id }}">
<div class="comment_name g_6">
<div class="comment_count right">
<a name="c{{ comment.id }}" href="{{ comment.get_absolute_url }}" {% ifnotequal comment.person_name null %}title="Permalink to {{ comment.person_name }}'s comment"{% endifnotequal %} class="comment_count">{{ forloop.counter }}</a></div>
Wrote by <strong>{% if comment.user_url %}{{ comment.user_name }}{% else %}{{ comment.user_name }}{% endif %}</strong> on {{ comment.submit_date|date:"F j, Y" }} - {{ comment.submit_date|date:"P" }}
</div>
<div class="comment_body g_6">{{ comment.comment|urlizetrunc:"60"|safe }}</div>
</div>
{% endif %}
{% endfor %}
<div class="clear"></div>
</div>
{% else %}
No comments yet.
{% endif %}
I think the problem lies in the get_comment_list templatetags :)
Thanks in advance
I think django-pagination might be what you're looking for.
http://code.google.com/p/django-pagination/ (screencast available)
Django also has a built in Pagination system
