Usage

1. Add drc in INSTALLED_APPS in django settings.py. drc is short for django-redis-counter.

INSTALLED_APPS = [
    ...
    'drc',
    ...
]

2. Define counter models in app’s models.py.

from drc.models import Counter

class Page(models.Model):
    title = models.CharField(max_length=32)
    ...

class PageCounter(Counter):
    pass

3. Call incr in views.

def display_page(request, page_id):
    page = Page.objects.get(pk=page_id)
    page_visit_number = PageCounter.incr(page)
    return render(request, "page.html", {
        "page": page,
        "page_visit_number": page_visit_number,
    })

4. Create a script to dump cached data to database. Name the script to page_counter_dump.sh or what ever you like.

#!/bin/bash
cd /your/project/path
python manage.py drc-dump

5. Add dump task as schedule job, e.g. crontab job.

* * * * * page_counter_dump.sh # dump the cached data every minutes
1 * * * * page_counter_dump.sh # dump the cached data every hour.
