How to use Django views and template tag simultanosly?

In my Django-template:

<div class="A">
    {% url renders_data object.id %}
</div>
<div class="B">
    {% render_data object.id %}
</div>

Div A is common way to call a method in views.py whereas Div B is for template tags.

User will open a link. Let's say: /myapp/test/ a page will open contain two template tag section at the page. Name of this tag is render_data I want to load the data into each template tag with Ajax. To work with it we need request.ajax:. That is why i thought to write views method. I thought to complete it with the following way:

  • I wrote the exact copy of template tag in views.py (renders_data with passing object_id parameter) and render it to the right template. When i open the maypp/test after removing the div A from template. It shows the URL (myapp/test/<object_id>) in each template tags section (each corner) except the data. Is their any possibility to show the context except this URL See the image when i choose this option

  • Second i also thought to import views method (renders_data) in template tag (render_data). So that data will display in each corner and request.Ajax: will also work. if this can be possible then how?

    • I am not able to solve this issue. please help me :(

    See how the render_data looks like:

     @register.simple_tag
 def render_widget(object_id):
     from myapp.plugins.model import Widgetsetting
     widget_setting = Widetsetting.objects.get(id = object_id)
     widget = widget_settings.get_widget()
     template_name = widget.template_name
     context = widget.context(widget=widget_settings)
     t =  get_template("widgets/%s" % template_name)
     return t.render(Context(context))

    From the code you've posted something like below should work...

    in views.py:

    from django.http import HttpResponse
from netadmin.plugins.templatetags.widgets import render_widget

def ajax_render_data(request, object_id):
    return HttpResponse(render_widget(object_id))

    in your django template:
    (you said you want several of these on the page, so I'm going to use a loop in the django template, I don't know what your widget collection is called but I'm sure you can work it out for your particular case)

    <div class="widgets-container">
    {% for widget_settings in widgetsettings.objects.all %}
    <div class="widget-content" id="widget-content-{{ widget_settings.pk }}">
        not loaded yet
    </div>
    {% endfor %}
</div>

<script>
// here we use django to render the ajax urls into an object
// in javascript so we can use it on the client side 
var ajax_urls = {
  {% for widget_settings in widgetsettings.objects.all %}
    "{{ widget_settings.pk }}: "{% url ajax_render_data widget_settings.pk %}"{% if not forloop.last %},{% endif %}
  {% endfor %}
};

// (I'll assume you're using jQuery)
// start the ajax calls when the page is loaded:
$(document).ready(loadWidgets());

function loadWidgets() {
    // loop over the urls we provided from django:
    jQuery.each(ajax_urls, function(widget_id, url) {
        // do the ajax call:
        $.get(url, function(data) {
            // put the content into the widget div:
            $('#widget-content-'+widget_id).html(data);
        });
    });
}
</script>

    in urls.py:

    urlpatterns += patterns('netadmin.plugins.ajax_view',
    url(r'^ajax/(?P<object_id>\d+)/$', 'ajax_render_data', name='ajax_render_data'),
)
