Add timestamps to an existing table

Question

I need to add timestamps (created_at & updated_at) to an existing table. I tried the following code but it didn\'t work.

class          


        

Answer 1

I'm on rails 5.0 and none of these options worked.

The only thing that worked was using the type to be :timestamp and not :datetime

def change
    add_column :users, :created_at, :timestamp
    add_column :users, :updated_at, :timestamp
end
