Simple Age Verification Middleware

Simple middleware+decorator to handle age verification. Modeled after `django.contrib.sessions.middleware` to add an attribute to `request.user` called `is_age_verified` with consideration to [snippet 1002](http://www.djangosnippets.org/snippets/1002/). Decorator modeled after `django.contrib.auth.decorators.login_required` Installation: Create `verify_age` URLconf in `urls.py` Create age verification page that URLconf points to Define `settings.VERIFY_AGE_URL` based on URLconf Add `age_verification.AgeVerificationMiddleware` to `MIDDLEWARE_CLASSES` Import both `age_verification_required` and `REDIRECT_FIELD_NAME` in `views.py` Implement `age_verification.AgeVerification.verify` somewhere to set session attribute on successful verification. Use `@age_verification_required` decorator for views requiring age verification Example urls.py: urlpatterns += patterns('mahalo.answers.views', ... url(r'^verify_age/?$', 'verify_age', name="verify_age"), ... Example settings.py: ... VERIFY_URL = '/verify_age/' ... MIDDLEWARE_CLASSES += ( ... 'django.contrib.sessions.middleware.SessionMiddleware', 'django.contrib.auth.middleware.AuthenticationMiddleware', 'myproject.contrib.middleware.age_verification.AgeVerificationMiddleware', ... Example views.py: from myproject.contrib.decorators import age_verification_required, REDIRECT_FIELD_NAME from myproject.contrib.middleware.age_verification import AgeVerification ... @age_verification_required def some_view(request): return render_to_response("index.html", {}) def verify_age(request): # project specific template_vars = default_template(request) # form was posted if request.POST.has_key("month") and request.POST.has_key("day") and \ request.POST.has_key("year"): # "verify" user av = AgeVerification(request.session) av.verify() if request.POST.has_key(REDIRECT_FIELD_NAME): return HttpResponseRedirect(request.POST[REDIRECT_FIELD_NAME]) else: return HttpResponseRedirect(reverse("root")) # no form posted, show it else: if request.GET.has_key(REDIRECT_FIELD_NAME): template_vars["next"] = request.GET[REDIRECT_FIELD_NAME] return render_to_response("verify_age.html", template_vars) These examples assume `age_verification.py` lives in `myproject/contrib/middleware/` and `decorators.py` lives in `myproject/contrib/`
