How can I count the result of an ActiveRecord .group query? Chaining .count returns a hash

Question

I can use the following :

User.where(\"zip_code = \'48104\'\").group(\'users.id\').count

To get hashes like :

{195=>1, 1         


        

Answer 1

Since the first count() is returning a hash, use whatever Ruby enumerable operations you wish on it. Example:

User.where("zip_code = '48104'").group('users.id').count.count
