Cache Pagerfanta object or data

[spointecker]

Hello,

I tried to cache the pagerfanta result (the whole object Pagerfanta) with Symfony cache and I am getting the following error:
WARNING: Failed to save key "...." of type array.

(I used caching via Symfony\Contracts\Cache\CacheInterface and Symfony\Contracts\Cache\ItemInterface).

Is there a way to cache the response of Pagerfanta?

Symfony: 4.4.16
PagerfantaBundle: 2.8.0

Assuming you are using Doctrine, you would be better off using its query caching features instead of trying to cache a Pagerfanta instance. The Pagerfanta class, and many of the adapters, are stateful classes that rely on data from a particular request and aren't really well suited to be cached themselves.
