trying to introduce django custom templatetags - some jinja also involve

[django-newb]

I am working on a project where I used a open source framework. Here is the link for the opensource framework:  https://github.com/ASKBOT/askbot-devel. I wanted to add a/b testing to it and after doing some research I found out django-lean. I am not an expert in django but I manage to bring the strip down version of the django-lean to my version of askbot-dlevel. I used the blog post. But my problem is that I am getting following error:

TemplateSyntaxError at /questions/
Encountered unknown tag 'experiment'.
Request Method: GET
Request URL:    http://localhost:8001/questions/
Django Version: 1.4.10
Exception Type: TemplateSyntaxError
Exception Value:    
Encountered unknown tag 'experiment'.

Just to give more information how I incorporate django-lean: As the blog-post mention I only use the experiments module: I added experiments folder from django-lean inside askbot folder and expose it as another install-app using settings file. So now it looks like another application.

I copied experiments.py and smartif.py to askbot-dlevel/templatetags because thats the right thing to do based on he django documentation: also I copied content of the templates folder in the django-lean to askbot-dlevel project's templates folder. So here is how the project looks like: 

askbot-dlevel
|__experiments
|__OtherApps
templates
|__experiments
|__other_templates

In askbot-dlevel there is a utils folder and in that there is decorators.py, I added the following:

def set_experiment_user(view_func):
    '''Decorator for setting the WebUser for use with ab split testing assumes
    first argument is the request object'''
    @functools.wraps(view_func)
    def decorator(request, *args, **kwargs):
        WebUser(request).confirm_human()
        return view_func(request, *args, **kwargs)
    return decorator

This is a slight modification respect to what the blog-post has mentioned but the logic is still the same. At the point blog-post advise to add it to the views so I added to a view in the askbot-dlevel project: 

@csrf.csrf_protect
@decorators.set_experiment_user
def ask_widget(request, widget_id):

    def post_question(data, request):
        thread = models.Thread.objects.create_new(**data)
        question = thread._question_post()
        request.session['widget_question_url'] = question.get_absolute_url()
        return question

    widget = get_object_or_404(models.AskWidget, id=widget_id)
    ...

after this I added the necessary code to the template file which would add all incoming users to the current experiment that is live on the. Now askbot-dlevel uses jinja2. I but I first tried as the blog post mention because I really don't have a good idea of jinja. 

So in sidebar.html of the adkbot-dlevel I added the following: 

{% import "macros.html" as macros %}

{% load experiments %}
{% experiment experiment_name top_contributors %}
{% if contributors and settings.SIDEBAR_MAIN_SHOW_AVATARS %}
    {% include "widgets/contributors.html" %}
{% endif %}
{% endexperiment %}

But that gave me the error that I put at the start of this post. As the blog post mention things should work. Using the admin console I have created an experiment and the name of the experiment is top_contributors. And if things run all users would be in the experiment. But I am getting above mention error which tells me template tags have not been registered.

So I tried my best to convert this to jinja format and tried the following: 

{% if experiments.experiment('top_contributors') %}
{% if contributors and settings.SIDEBAR_MAIN_SHOW_AVATARS %}
    {% include "widgets/contributors.html" %}
{% endif %}
{% endif %}

But that gave me following error: 

UndefinedError at /questions/
'experiments' is undefined
Request Method: GET
Request URL:    http://localhost:8001/questions/
Django Version: 1.4.10
Exception Type: UndefinedError
Exception Value:    
'experiments' is undefined
Exception Location: ..python2.7/site-packages/Jinja2-2.7.1-py2.7.egg/jinja2/environment.py in getattr, line 397
Python Executable:  ../ABFrameWork/bin/python

Hopefully someone can help on solving this problem.

Thank You,
