in my web site i want to show the user ratings for that i used the infinite scroll but i am facing one problem.
when it first loads the data before calling the <a class="infinite-more-link" href="?page={{ ratings.next_page_number }}"></a> it is showing the star with the count of vote,but when after calling the <a class="infinite-more-link" href="?page={{ ratings.next_page_number }}"></a> it is not showing the star.

i have tried to put the <link href="https://cdnjs.cloudflare.com/ajax/libs/font-awesome/5.9.0/css/all.min.css" rel="stylesheet"> inside the class="infinite-item" but it does not help.what might be the reason for that ? Thanks.
It doesn't look like .stars() will look for new elements being added to the DOM. You should look for a callback function configuration option within Waypoint.Infinite that you can call .stars() on the new elements.
I am experimenting with creating a slideshow that has four images, for example. And the thing is I want to create a link button with its own url link for each image. But what I have done is created four link buttons that appears on the slideshow, instead of the one link button that changes along with each image, and with its own url link.

I am totally lost as to what to do, as I am very very new to this. I would think I somehow need to link the images with the urls and link buttons etc, but have no idea how to code it so that each image has its own link button and url link...Any help? Any examples?
Hold on, you are not using much of angular here. I think its django or some other template with {% if %} .
Use something like:
<div ng-repeat="object in objects">
{{object.name }}
<img src="{{ object.img_path}}" />
</div>
For look try this link for ng-repeat
For the functionality u need, I would recommend you to look into cleaner approach of Carousel
I have built a javascript macro and a form theme to render form collections on my website with symfony2.
{{ if prototype is defined }}, I add a 'Add button'.
So far I also have a delete button.
I would like to remove this delete button if 'allow_delete' is not set to true but I can't figure out how to find this in twig.
When I look at my field.vars, there is no allow_delete option. field.vars.attr does not either. How can I do this?
The allow_delete option is a children of you form field.
{% for widget in form.YOURFIELD.children %}
{% if widget.get('allow_delete') %}
//Do your stuff
{% endif %}
{% endfor %}
For those who might be interested, here is my complete solution:
Collections are rendered as tables. Headers are labels or the string
'option' in case of a checkbox.
If the attribute data-label is set in the form, the option is
replaced by the value of data-label.
If allow_add is set to true, an add button is added
if allow_delete is set to true, a delete button is added.
{% block collection_widget %}
{% spaceless %}
<div class="collection">
{% if prototype is defined %}
{% set attr = attr|merge({'data-prototype': block('collection_item_widget') }) %}
{% endif %}
{% if form.vars.allow_delete is defined and form.vars.allow_delete %}
{% set allow_delete = true %}
{% else %}
{% set allow_delete = false %}

I have been working through the Tango with Django exercises to cut my teeth into Django. Almost done but having a problem with the Ajax part.
Ajax function to auto_add a page is not being called. Idk what the problem is since the other functions are being called.
On the shell prompt, there is no call to the ajax function at all. Help needed.
Pertinent code attached. It is the same as on the website link above.
static/rango-ajax.js
$('.rango-add').click(function(){
var catid = $(this).attr("data-catid");
var title = $(this).atrr("data-title");
var url = $(this).attr("data-url");
$.get('/rango/auto_add_page/', {category_id: catid, url: url, title: title}, function(data){
$('#pages').html(data);
me.hide();
});
});
templates/rango/category.html
{% if user.is_authenticated %}
<button data-catid="{{category.id}}" data-title="{{ result.title }}" data-url="{{ result.link }}" class="rango-add btn btn-mini btn-info" type="button">Add</button>
{% endif %}
rango/views.py
#login_required
def auto_add_page(request):
context = RequestContext(request)
cat_id = None
url = None
title = None
context_dict = {}
if request.method == 'GET':
cat_id = request.GET['category_id']
url = request.GET['url']
title = request.GET['title']
if cat_id:
category = Category.objects.get(id=int(cat_id))
p = Page.objects.get_or_create(category=category, title=title, url=url)
pages = Page.objects.filter(category=category).order_by('-views')
#Adds our results list to the template context under name pages.
context_dict['pages'] = pages
return render_to_response('rango/page_list.html', context_dict, context)
rango/urls.py
urlpatterns = patterns('',
url(r'^$', views.index, name='index'),
url(r'^goto/$', views.track_url, name='track_url'),
url(r'^add_category/$', views.add_category, name='add_category'),
url(r'^auto_add_page/$', views.auto_add_page, name='auto_add_page'),
Complete code is at this link.
your code is good, the only thing what you have to do is to define your template in /tango/templates/rango/page_list.html. This template have the following code:
{% if pages %}
<ul>
{% for page in pages %}
<li>
{{ page.title}}
{% if page.views > 1 %}
({{page.views}} views)
{% elif page.views == 1 %}
({{page.views}} view)
{% endif %}
</li>
{% endfor %}
</ul>
{% else %}
<strong> No Pages currently in category. </strong>
{% endif %}
And inside of your category template you must define the following code:
% if category %}
{% if user.is_authenticated %}
Add a new Page <br>
{% endif %}
{% if pages %}
<div id="pages">
<ul>
{% for page in pages %}
<li>
{{ page.title}}
{% if page.views > 1 %}
({{page.views}} views)
{% elif page.views == 1 %}
({{page.views}} view)
{% endif %}
</li>
{% endfor %}
</ul>
</div>
{% else %}
<strong> No Pages currently in category. </strong>
{% endif %}
{% else %}
The specified category {{ category_name }} does not exist!
{% endif %}
I'm working through this section of the tutorial now and just want to add to Héctor's answer. To avoid duplicating the code to display the list of pages I did the following:
I added a get_page_list() method to tango/rango/templatetags/rango_extras.py, similar to the get_category_list() method used to display a list of categories in an earlier section of the tutorial.
from rango.models import Page
#register.inclusion_tag("rango/page_list.html")
def get_page_list(category):
pages = Page.objects.filter(category=category) if category else []
return {'pages': pages}
Then we just need to load rango_extras and call the get_page_list() method in tango/templates/rango/category.html.
{% extends 'rango/base.html' %}
{% load rango_extras %}
<!-- Existing code -->
{% if category %}
<!-- Existing code to show category likes and like button -->
<div id="page_list">
{% get_page_list category %}
</div>
<!-- Existing code to show search if user is authenticated -->
{% else %]
The specified category {{ category_name }} does not exist!
{% endif %}
This allows you to display the list of pages when a category page is first loaded and then refresh it if a category is added from the search area, without having to duplicate any code.
