Rails Admin - Show field even when blank in show action


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:

empty desc

Example with populated description field:

pop desc

Thanks


Solution

  • 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
