Rails Admin - Show field even when blank in show action

Question

I'm using rails admin, and I need to display fields in the show action if they are blank as well as if they are populated.

show do
  field :name
  field :key
  field :description
  field :type
end

At the moment, if description is empty (which is allowed) it will only display name, and fields. I need it to display all 3 fields regardless of if they are populated or not.

Update: Pictures

Example with empty description field:

Example with populated description field:

Thanks

Whenever rails admin detects a falsy value it does not show the field, so an empty string or nil would hide it. You have to give it a non falsy value as a default like this

show do
  field :name
  field :key
  field :type
  field :description
    formatted_value do
      value || '-'
    end
  end
end
