Django - How to use sorl-thumbnail?

Question

I'm using Django with PostgreSQL but I need to use some App to handle thumbnails. There is an app very well rated called Sorl-Thumbnail

In the installation instructions says that I need to use a key value/caching system.

My doubt is: Can I use PostgreSQL database as cache or I will must to install memcached or redis?

I'm currently not using any caching mechanisms, the website is targeted for low traffic.

Answer 1

You can use the database cache backend, or even the FS cache backend. By "you can", I mean that "it will work". Just configure it normally for your django project and sorl-thumbnail will use it.

As per sorl-thumbnail documentation:

a cached database which requires no special installation to your normal Django setup besides installing a proper cache like memcached

But it won't be as awesome as memcached or redis.

(Also: why does sorl-thumbnail require this now ? It used to just check the FS to ensure that the thumbnail exists or else create it)
