[Rails] Re: [Arel]Building query, but can't get a proper output

I have the following code:

      advertisements_arel = Advertisement.order("advertisements.id
DESC").arel
      @advertisements = (params[:website_id].present? ?
advertisements_arel.where(:website_id => params[:website_id]) :
advertisements_arel).to_a

It returns a struct Arel::SelectManager::Row data
But I'd like it to return an array of Advertisement objects (like it
would normally do) so I can iterate over it more easily. Anyone know how
to do that?

If you remove the .arel you get an ActiveRecord::Relation which you can iterate as if it were an Array, plus you can keep appending .where(...) as in your code
