      """Delete an object in Redis using a pipeline.
  
      Deletes all fields defined by the template.
  
      Arguments:
          template: a dictionary containg the keys for the object and
              template strings for the corresponding redis keys. The template
              string uses named string interpolation format. Example:
  
              {
                  'username': 'user:%(id)s:username',
                  'email': 'user:%(id)s:email',
                  'phone': 'user:%(id)s:phone'
              }
  
          indexes: a dictionary containing the values to use to construct the
              redis keys: Example:
  
              {
                  'id': 342
              }
