Module: Shared::MatrixHooks::Dynamic

Extended by:
ActiveSupport::Concern
Included in:
Tag, TaxonName
Defined in:
app/models/concerns/shared/matrix_hooks/dynamic.rb

Overview

Code to update (dynamic) matrix content based on what goes on with this instance.

This code handles first creates and changes, not use increments nor destroys.  It ensures there
are rows/columns created when changes happens, that's it.

This module handles a once-removed abstraction edge case.

!! All modules including this code must implement either one or both (row/column) of the in/out “Interface” methods

See spec/models/taxon_name/matrix_hook_spec.rb for specs and exercising.
