# It's used whenever a rel type is automatically determined based on ActiveRel model name or

class << self
# 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

# @param [String,Symbol] type The raw string or symbol to be used as the basis of the relationship type
