I've got a query like the following:

@tags = Tag.find(:all, :limit => 20, :conditions => "id != 22 and id != 47" , :order => "count DESC")

My understanding is the ActiveRecord returns an array of hash objects to @tags. so @tags is actually an array full of hashes.

the tags table has the following fields:

id, name, count, updated_at

The query returns the top 20 tags sorted by count into @tags

How can I then sort @tags by the 'name' field so I will have the top 20 tags sorted by alpha name?

@tags.sort! { |t| t.name }

@tags.sort! { |t| t.name }    Oops. That should be:

  @tags.sort! { |a,b| a.name <=> b.name }

or, alternatively:

  sorted_tags = @tags.sort_by { |t| t.name }
