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

I'm not seeing an error when template inheritance seems to fail. I don't see content from the child template but I don't see a 'TemplateNotFound' error. If I change the path to the parent template to 'notthefilename.html' I still don't see an error. Is there a way to make template inheritance fail noisily? I have no idea why this is not working even though I have a similar inheritance in a adjacent folder that is working as expected.
generic_create.html The text 'hello2' is rendering.
{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div style= "padding-top: 30px">
<form method="post">{% csrf_token %}
{% if model_name == 'TransactionsTable' %}
<div>
{% block transactions_create %}
hello2
{% endblock transactions_create %}
</div>
{% else %}
{{ form |crispy }}
{% endif %}
<div id="container">
<input type="submit" class="btn btn-default" value="Save">
Cancel
<div>
</form>
</div>
{% endblock content %}
transactions_create.html - The content 'Hello1' is not rendering
{% extends "generic_create.html" %}
{% load static %}
{% block transactions_create %}
Hello1
{% endblock transactions_create %}
Thanks to #Daniel Roseman's comment I realized I was performing the inheritance backwards. I was also over-complicating things. Using the include tag I was able to perform the sort of inheritance I was hoping to achieve very easily.
generic_create.html
{% extends "base.html" %}
{% load crispy_forms_tags %}
{% block content %}
<div style= "padding-top: 30px">
<form method="post">{% csrf_token %}
{% if model_name == 'TransactionsTable' %}
<div>
{% include "transactions_create.html" %} #NOTE: Here I removed the block and added 'include'.
</div>
{% else %}
{{ form |crispy }}
{% endif %}
<div id="container">
<input type="submit" class="btn btn-default" value="Save">
Cancel
<div>
</form>
</div>
{% endblock content %}
transactions_create.html
Hello1 #removed all of the extend and 'block' code. 'include' just renders the html directly.
That's it! 'include' really simplified things.
I am using Flask, mongoengine for a project and I am trying to get basic stuff working from http://docs.mongodb.org/manual/tutorial/write-a-tumblelog-application-with-flask-mongoengine/
After implementing everything from above link I added a new field for "tags" in Post and when I try to create a post, my tags doesn't show a input box.
Any help is appreciated.
My code and screenshot below
class Post(db.DynamicDocument):
created_at = db.DateTimeField(default=datetime.datetime.now, required=True)
title = db.StringField(max_length=255, required=True)
slug = db.StringField(max_length=255, required=True)
comments = db.ListField(db.EmbeddedDocumentField('Comment'))
tags = db.ListField(db.StringField(max_length=30)) # New field I added
template form
{% macro render(form) -%}
<fieldset>
{% for field in form %}
{% if field.type in ['CSRFTokenField', 'HiddenField'] %}
{{ field() }}
{% else %}
<div class="clearfix {% if field.errors %}error{% endif %}">
{{ field.label }}
<div class="input">
{% if field.name == "body" %}
{{ field(rows=10, cols=40) }}
{% else %}
{{ field() }}
{% endif %}
{% if field.errors or field.help_text %}
<span class="help-inline">
{% if field.errors %}
{{ field.errors|join(' ') }}
{% else %}
{{ field.help_text }}
{% endif %}
</span>
{% endif %}
</div>
</div>
{% endif %}
{% endfor %}
</fieldset>
{% endmacro %}
rendering form code
{% extends "admin/base.html" %}
{% import "_forms.html" as forms %}
{% block content %}
<h2>
{% if create %}
Add new Post
{% else %}
Edit Post
{% endif %}
</h2>
<form action="?{{ request.query_string }}" method="post">
{{ forms.render(form) }}
<div class="actions">
<input type="submit" class="btn primary" value="save">
Cancel
</div>
</form>
{% endblock %}
From what I can gather, your problem is you're telling WTF to render the tags field, but WTForms doesn't know how to handle that information.
From looking at the Flask-MongoEngine documentation, it seems the ListField is just a FieldList as WTForms refers to it.
Currently you're not actually defining the form independently in WTForms, you're just using the magic included in Flask-MongoEngine, so my first attempt would be to add some more logic to your macro, add a {% elif field.type == 'ListField' %} and try and discover what's contained in there to iterate through to produce your form. From having a quick look at the source-code, something like the following might work.
{% elif field.type == 'ListField %}
{# render_the_group_label #}
{% for subfield in field.entries %}
{% if subfield.type == 'StringField' %}
{# render_the_subfield #}
{% endif %}
{% endfor %}
...
That code will need to be worked on, but hopefully it'll point you in the right direction. Otherwise, I'd actually define the form seperately in WTForms to give you a bit more control on the code-side. Luckily they provide a csv tag example which should help you if you need to go that route. I wrote a guide that takes a different route using #property decorators to achieve a similar effect, which again, might at least point you towards the finish line.
Im trying to implement commenting on my site using the comments framework. I've followed the documentation:
https://docs.djangoproject.com/en/dev/ref/contrib/comments/
https://docs.djangoproject.com/en/dev/ref/contrib/comments/example/
My template looks like:
{% extends "pbase.html" %}
{% load comments %}
{% block bcontent %}
<div class="main">
<< back
<!-- Image -->
<ul>
{% if image.title %}
<div class="title">{{ image.title }}</div>
{% endif %}
<ul>
<img border="0" alt="" src="{{ media_url }}{{ image.image.name }}" width="900" />
</ul>
</ul>
{% load comments %}
{% get_comment_count for photo.image object_pk as comment_count %}
<p>{{ comment_count }} comments have been posted.</p>
{% render_comment_list for photo.image object_pk %}
{% render_comment_form for photo.image object_pk %}
</div>
{% endblock %}
On my page the number of comments is show but not the comments themselves or the form. What am I missing?
Thanks
photo.image should be just image. I know image is correct because you use it elsewhere in the template, and if it were wrong, you'd notice.
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">

</a>
<a href="http://{{ book.homepage }}" class="book_website_link" title="Book website" target="_blank">

</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.
