Nice, I didn't know the association is still cached when using a block, I think we'll go with that.
And we'll consider if perhaps we're much better off using the tactical_eager_loading plugin. My current preference is to have data retrieval more explicit, and to have one place where we can see everything we're loading. The approach you recommended solves that nicely, thank you :) Kind regards, Janko On 8 Feb 2019, 16:09 +0100, Jeremy Evans <[email protected]>, wrote: > On Friday, February 8, 2019 at 3:32:09 AM UTC-8, Janko Marohnić wrote: > > I'm looking for an easy way to apply eager loading of any nested > > association for a single record, ideally performed at the same time when > > the record is retrieved.
