Rails ActiveAdmin max column length

Programming in ruby or rials – ror: Rails ActiveAdmin max column length on newest questions tagged ruby-on-rails – Stack Overflow

In a Rails app using ActiveAdmin, one of my fields is printing an enormous length of text in a very narrow column and causing a single db row to take up an entire screen vertically. I only want ActiveAdmin to show the first ~50 chars with an ellipsis if it exceeds.

index do
  column :too_long
...

I am looking for something like this

index do
  column :too_long, :max => 50
...
