def dwc_occurrence_attribute_values(mode = :all)
  [id, dwc_occurrence.id] + self.class.dwc_attribute_vector(mode)[2..-1].collect{|a| a.name}.collect{|f| dwc_occurrence.send(f) }
end

#dwc_occurrence_attributes(taxonworks_fields = true) ⇒ Object

!! This is expensive, it recomputes values for every field. !! See dwc_occurrence

Returns:

  • Hash of field: value

def dwc_occurrence_attributes(taxonworks_fields = true)
  a = {}
  self.class::DWC_OCCURRENCE_MAP.each do |k,v|
    a[k] = send(v)
  end

  a[:occurrenceID] = dwc_occurrence_id
  a[:basisOfRecord] = dwc_occurrence_basis

  if taxonworks_fields
    a[:project_id] = project_id

    # TODO: semantics of these may need to be revisited, particularly updated_by_id
    a[:created_by_id] = created_by_id
    a[:updated_by_id] = updated_by_id
    # !! Do not set updated_at here !!
  end

  a
end

#dwc_occurrence_basis ⇒ Object

Moved here from DwcOccurrence#basis since that method is only called in before_validate, which never gets called on the dwc_occurrence_attributes path here that happens when something like adding a new BiocurationClass triggers a background job set_dwc_occurrence call to update dwc_occurrence.

Returns:

  • String the Darwin Core basisOfRecord value for this occurrence
