- Defined in:
- app/models/renalware/pathology/observations_grouped_by_date_query.rb
Overview
A custom relation-like object, implementing a kaminiari-like pagination interface. Its a query object but means to be used like a relation. If passed into a view you can do = paginate(relation). See ObservationsGroupedByDateTable for intended usage.
.all() returns a jsonb hash of OBX results for each day a patient had an observation. Only returns observations whose code matches observation_descriptions
Example usage:
observation_descriptions = ..
rows = ObservationsGroupedByDateQuery.new(
patient: patient,
observation_descriptions: observation_descriptions,
per_page: 50,
page: 1
)
Example output:
patient_id observation_date observations
