Ok, I'll try. Meanwhile, can you take a look on this has 'IF(item_variations.item_photo_id=0,items.picked_at,item_variations.picked_at)', as: :combined_picked_at, type: :datetime
I was able to create combined_picked_at attribute and sort by it. But for some reason only item_variations.picked_at goes to that calculated field and items.picked_at are ignored. Is this definition correct? Maybe I'm missing something here? On Monday, 3 November 2014 18:37:00 UTC+2, Misha Slyusarev wrote: > > I would like to be able ordering by a calculated field.
