.rel_transformer ⇒ Object

Determines how relationship types should look when inferred based on association or Relationship 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
