Returning Rendered Html via Ajax

Question

I am trying to return html via and Ajax call and I have the following snippet of code in my view

if request.is_ajax(): 
t = loader.get_template('frontend/scroll.html')
html = t.render(RequestContext({'dishes': dishes})
return HttpResponse(json.dumps({'html': html}))

and my Ajax

  $.ajax({
           type: "POST",
           url: "/filter_home", 
           data: {'name': 'me', 'csrfmiddlewaretoken': '{{csrf_token}}'},
           success : function(data) {
                $('.row.replace').html(data);
            }
   });

and it throws the following error

Exception Value:    'dict' object has no attribute 'META'
Exception Location: /opt/bitnami/apps/django/lib/python2.7/sitepackages/django/core/context_processors.py in debug, line 39

what am I doing wrong?

Answer 1

There are a few issues with your code:

You need to use render_to_string.

You also don't need to convert your HTML into json because you are replacing the contents directly.

Putting all this together you have:

from django.template.loader import render_to_string
from django.http import HttpResponse

if request.is_ajax():
    html = render_to_string('frontend/scroll.html', {'dishes': dishes})
    return HttpResponse(html)

In your front end, you need:

$.ajax({
        type: "POST",
        url: "/filter_home", 
        data: {'name': 'me', 'csrfmiddlewaretoken': '{{ csrf_token }}'},
        success : function(data) {
             $('.row.replace').html(data);
         }
});
