django onclick load template to {% block %} using ajax - ajax

Question

Im creating a webapplication in django to which Im very new.
what I want to do is on user click open a modal window (basically just an absloute positioned div) which contains a {% block some_content%} tag. This block should then contain either a log in form or a register form (or anything else). I want to load this using ajax (so that nothing is loaded in vain).
here is the part of my template where i want the stuff to appear:
<div id="modal" style="position: absolute; top: 60px; left: 100px; height: 400px; width:700px; background: #777; z-index: 20">
<div class="button">Test</div>
<br />
{% block test_content %}{% endblock test_content %}
</div>
and here is my ajax.py
#dajaxice_register
def tester1(request, user_id):
print "test " + user_id
#contenxt = Context({'items': range(2)})
print "1"
return_str = render_block_to_string('my_site/testr.html', 'test_content')
print "7"
return HttpResponse(return_str)
Im using snippet http://djangosnippets.org/snippets/942/
following the print "#" leads me to believe that this works all the way up to the
return HttpResponse(return_str)
where nothing seems to happen, not even an error message.
forgot to include the template i want to load to the block:
{% extends "my_site/header.html" %}
{% load url from future %}
{% block test_content %}
<div style="background: red; height: 70%; width:90%">
<span>HEJ!!!</span>
</div>
{% endblock test_content %}
if there is a better approach Ill be glad to know about it but remember, Im new to django so please go slow.

Answer 1

You seem to be using the Dajax framework. Have a look at the examples there.
Some of those examples may be outdated so take a look at this site.
If you have Dajax and Dajaxice installed you can do something like
<div id="test_content"></div>
load ajax content
ajax.py in your app
#dajaxice_register
def ajax_test:
str = 'Hello World'
dajax = Dajax()
dajax.assign('#test_content', 'innerHTML', str)
return dajax.json()

Answer 2

So, here is my solution:
I have Dajax installed. The reason it didn't work is below but here is a complete solution that works.
html:
<input type="button" name="testerbutton" value="Test" id="testerbutton" onclick="Dajaxice.my_site.tester1(Dajax.process);">
<br />
<div name="result" value="" id="result">
ajax.py:
#dajaxice_register
def tester1(request):
dajax = Dajax()
str = render_to_string('my_site/testr.html')
dajax.assign('#result', 'innerHTML', str)
return dajax.json()
testr.html:
<div style="background: red; height: 70%; width:90%">
<span>HEJ!!!</span>
</div>
And the most important part -- something it appears I can only blame myself for: make sure you correctly import jquery.dajax.core.js in your header. Otherwise Dajax.process does nothing.
Thanks #pyronic for the help.
