def aggregate(query)
  #query.model.last_query = query
  #y query
  _layout = layout(query.model)
  opts = fmp_options(query)
  opts[:template] = self.class.fmresultset_template_path
  prms = fmp_query(query.conditions) #.to_set.first)
  #[prms.empty? ? _layout.all(:max_records=>0).foundset_count : _layout.count(prms)]
  [prms.empty? ? _layout.view.total_count : _layout.count(prms)]
end

#create(resources) ⇒ Integer

Persists one or many new resources

Adapters provide specific implementation of this method

Examples:

adapter.create(collection)  # => 1

Parameters:

  • resources (Enumerable<Resource>) —

    The list of resources (model instances) to create

Returns:

  • (Integer) —

    The number of records that were actually saved into the data-store
