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 <https://bitbucket.org/akoha/django-lean/wiki/Home>. 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<http://alexkehayias.tumblr.com/post/15951774761/ab-split-testing-django>. But my problem is that I am getting following error:
TemplateSyntaxError at /questions/Encountered unknown tag 'experiment'.Request Method: GETRequest URL: http://localhost:8001/questions/Django Version: 1.4.10Exception Type: TemplateSyntaxErrorException 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<https://docs.djangoproject.com/en/dev/howto/custom-template-tags/>: 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<http://alexkehayias.tumblr.com/post/15951774761/ab-split-testing-django>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_userdef 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 undefinedRequest Method: GETRequest URL: http://localhost:8001/questions/Django Version: 1.4.10Exception Type: UndefinedErrorException Value: 'experiments' is undefinedException Location: ..python2.7/site-packages/Jinja2-2.7.1-py2.7.egg/jinja2/environment.py in getattr, line 397Python Executable: ../ABFrameWork/bin/python Hopefully someone can help on solving this problem.
