Hello,
I am using rails and this ajax-datatables-rails gem in the back end.
I am having difficulty with dealing with columns that are not stored in the database. I realize this has as much to do with the gem as it does with datatables but I was hoping someone could give me some thoughts on what the best way to deal with is. Specifically, the present challenge is sorting by the calculated field.
I have a Price model with cost , size attributes and a #cost_per_unit method (cost/size). I want to display and sort cost_per_unit in datatables and I want to sort by cost_per_unit. Does anyone have some ideas on what the best way to deal with this is?
