Question

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
...

Answer 1

you can use something like

 index do
   column "TOO LONG" do |object|
      object.too_long.slice(0, 50)
   end
  #.....
 end

I have not tested this but something like this should work.
