Overview

A helper class wrapping a custom relation object which has aggregated a patient’s pathology results by date of observation using raw SQL + PGResult. Note we implement the required interface for kaminari pagination (we delegate to the underlying relation to achieve this).

This class exists to make the underlying PGResult set (wrapped in a custom relation-like object) easier to consume.

Example usage: (ruby) codes = %i(HGB PLT WBC) rows = ObservationsGroupedByDateQuery.new(patient_id: 1, codes: codes) table = ObservationsGroupedByDateTable.new(rows: rows, codes: %i(HGB PLT WBC)) (html) table

tr
  td Date
  - table.codes do |code|
    td= code
tbody
  tr
    - table.each_row do |row|
      td= l(row.observed_on)
      - table.codes.each do |code|
        td= row.result_for(code)
