Hi everyone-

Model.update\_all works and changes the records, but it’s not changing  
the updated\_at field. Am I doing something wrong or is this by  
design?

Thanks,  
Dino

Model.update\_all works at a lower level that all that stuff.

Thanks for the reply. I’m just trying to do some offline ranking, is  
there a better way to do this than update\_all?

You could easily make your call to update\_all update the updated\_at  
column (although it would be indiscriminate)
