RelTypeConverters

This module controls changes to relationship type based on Neo4j::Config.transform_rel_type. It’s used whenever a rel type is automatically determined based on ActiveRel model name or association type.

.rel_transformer

Determines how relationship types should look when inferred based on association or ActiveRel model name. With the exception of :none, all options will call underscore, so ThisClass becomes this_class, with capitalization determined by the specific option passed. Valid options: * :upcase - :this_class, ThisClass, thiS_claSs (if you don’t like yourself) becomes THIS_CLASS * :downcase - same as above, only... downcased. * :legacy - downcases and prepends #, so ThisClass becomes #this_class * :none - uses the string version of whatever is passed with no modifications
