ExportableDataSource

Corex\Config\Data\ExportableDataSource · interface · Config layer

A source that can hand its records to an export (spec 103, US10). A source has three shapes, and only the source knows them apart: the row its table shows, keyed by column ({@see QueryableDataSource::query()}); the record its detail view shows ({@see QueryableDataSource::record()}); and the row an export writes, which is this one. An export offers a column for every field the source declares and reads each cell from the row by the field’s key, so an export row carries a value under every key {@see fields()} declares. The export used to take the table’s rows for a query and the detail view’s record for a ticked row. Form submissions declare a field for each answer and show a summary in their table, so every answer’s column was written empty, and a ticked row lost its summary as well.
