Unable to change column position dynamically (Datagrid Rails gem)-CodePudding

I am trying to generate the columns of my table with data coming from a table that stores the order of each column that was created when the user rearrange the columns.

E.g in my property_grid.rb file I am trying to generate the columns using this array ["Attribute 1", "Attribute 2", "Attribute 3"].

["Attribute 1", "Attribute 2", "Attribute 3"].each do |v|
  case v
   when 'Attribute 1'
    column(:attribute_1)
   when 'Attribute 2'
    column(:attribute_2)
   when 'Attribute 3'
    column(:attribute_3)
  end
end

This works great the first time I reload the page but when the attribute array becomes ["Attribute 3", "Attribute 2", "Attribute 1"] it doesn't change.

If I add a comment or anything else to the property_grid.rb file then it seems to work. I don't understand why it only works if I manually add something to this file. Any idea why this is happening and how can I dynamically change the position of these columns?

you need to use map instead of each method. each method returns the initial array, map return the result of the block
