I considered moving the code to a service but I think that this code can be completely independent of the Open Food Network use case. It would be easy to move to a gem. The downcasing may need reconsidering for general use.

module OpenFoodNetwork
|
|
# Pluralize or singularize words.
|
|
#
|
|
# We store some inflection data in locales and use a reverse lookup of a word
|
|
# to find the plural or singular of the same word.
|
|
#
|
|
# Here is one example with a French user:
|
|
#
|
|
# - We have a product with the variant unit name "bouquet".
|
|
# - The I18n.locale is set to :fr.
|
|
# - The French locale contains:
|
|
# bunch:
|
|
# one: "bouquet"
|
|
# other: "bouquets"
|
|
# - We create a table containing:
|
|
# "bouquet" => "bunch"
|
|
# "bouquets" => "bunch"
|
|
# - Looking up "bouquet" gives us the I18n key "bunch".
|
|
# - We find the right plural by calling I18n:
|
|
#
|
|
# I18n.t("inflections.bunch", count: 2, default: "bouquet")
|
|
#
|
|
# - This returns the correct plural "bouquets".
|
|
# - It returns the original "bouquet" if the word is missing from the locale.
|
|
module I18nInflections
|
|
# Make this a singleton to cache lookup tables.
