Re: Lazy evaluation of django custom context processor in base.html

Hi,

Can anyone help on this. I want to pass value of "USERROLE" across all the django templates through "base.html". How to efficiently call custom context processor as it queries database for every page load.

Thanks,

Bijal

Hi,

Have created a custom context processor to retrieve extra user attribute from custom UserData model. Passing this variable in "base.html" template calls the custom context processor function on every request to render html page. Since it is a database query, how to efficiently call custom context processor in "base.html".

custom_context_processor.py

def global_settings_userrole(request):

    USERROLE = None

    if request.user.is_authenticated():

        u = UserData.objects.filter(username=request.user.username).values('role').first()

        USERROLE = u['role']

    return {

        'USERROLE': USERROLE

    }

Thanks,
