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.

Can someone help me to get rid of this problem ?
I've checked a lot of other questions and I haven't seen my particular scenario really addressed and I've tried a lot of things out without success.
What I have is a DJango for loop in my HTML code, and within the for loop is an if statement checking if each element from the list that is being looped through equals a certain value. If that is true, then an entry is created on the page. I need to dynamically print the element number (eg. entry 1 would display as 1. and entry 2 would display as 2.)
The two best attempts I have made are:
1.
<!-- this approach prints out 1 for each entry -->
{% with counter=0 %}
{% for q in questionnaire.questions %}
{% if q.answer %}
<div class="row"><h3>
{{ counter|add:1 }}. {{ q.name }}
</h3></div>
<!-- some other code-->
{% endif %}
{% endfor %}
{% endwith %}
{% for q in questionnaire.questions %}
{% if q.answer %}
<div class="row"><h3>
<span id="displayCount">0</span>. {{ q.name }}
</h3></div>
<!-- some other code-->
{% endif %}
{% endfor %}
<script type="text/javascript">
var count = 0;
var display = document.getElementById("displayCount");
count++;
display.innerHTML = count;
</script>
Any help would be appreciated
You can access the built-in counter of your for loop using forloop.counter. It starts at 1, you can also you forloop.counter0 if you'd like to start at zero.
{% for q in questionnaire.questions %}
{% if q.answer %}
<div class="row">
<h3>
{{ forloop.counter }}. {{ q.name }}
</h3>
</div>
<!-- some other code-->
{% endif %}
{% endfor %}
Filter your queryset in your view as to avoid issues with indexing and separating presentation from logic.

I am using Ajax with Django 1.10 to implement a like functionality ( a user likes an image posted by another user) on my website. I have the following code :
The views file :
#ajax_required
#login_required
#require_POST
def image_like(request):
image_id = request.POST.get('id')
action = request.POST.get('action')
if image_id and action:
try:
image = Image.objects.get(id=image_id)
if action == 'like':
image.users_like.add(request.user)
else:
image.users_like.remove(request.user)
return JsonResponse({'status':'ok'})
except:
pass
return JsonResponse({'status':'ko'})
def image_detail(request, id, slug):
image = get_object_or_404(Image, id=id, slug=slug)
return render(request,
'images/image/detail.html',
{'section': 'images',
'image': image})
In base.html :
<script src="https://ajax.googleapis.com/ajax/libs/jquery/2.1.4/jquery.min.js"></script>
<script src=" http://cdn.jsdelivr.net/jquery.cookie/1.4.1/jquery.cookie.min.js "></script>
<script>
var csrftoken = $.cookie('csrftoken');
function csrfSafeMethod(method) {
// these HTTP methods do not require CSRF protection
return (/^(GET|HEAD|OPTIONS|TRACE)$/.test(method));
}
$.ajaxSetup({
beforeSend: function(xhr, settings) {
if (!csrfSafeMethod(settings.type) && !this.crossDomain) {
xhr.setRequestHeader("X-CSRFToken", csrftoken);
}
}
});
$(document).ready(function(){
{% block domready %}
{% endblock %}
});
</script>
And finnaly in the detail.html :
{% extends "base.html" %}
{% block title %}{{ image.title }}{% endblock %}
{% block content %}
...
{% with total_likes=image.users_like.count users_like=image.users_like.all %}

{% else %}

While I mostly understand the code itself, I need help understanding in what orders the requests, the callback functions and everything else is executed ... something like : ,users clicks the like button, that information is passed to the server , it is being manipulated, data-base modified , sent back, the page changes ...
Tell me if any extra code ( models, urls etc. ) is needed. Could't post everything.
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
