[PATCH] Inconsistent behavior in pluralizing uncountable words

Reported by David Genord II | June 11th, 2010 @ 08:55 PM

I have noticed an inconsistent behavior in pluralizing uncountable words
"rice".pluralize => "rice" "WhiteRice".pluralize => "WhiteRices" "white_rice".pluralize => "white_rices"

I have attached a patch that corrects this behavior to give the expected results as follows
"rice".pluralize => "rice" "WhiteRice".pluralize => "WhiteRice" "white_rice".pluralize => "white_rice"

    • Tag changed from activesupport, inflections to activesupport, inflections, patch

    This patch looks good. There's obviously a bug that the test shows which is that existing compound word string, so a word like WhiteRice, is incorrectly pluralized to WhiteRices.

    I've attached an updated patch that refactors the implementation of pluralize to make it a little clear what's happening, IMHO. Rather than grok the regexps to try to infer the intent, I think it's clearer to just underscore the word and check to see if the last word is in the list of uncountables. It's not obivous what m = (/(.*_)([a-z]+)$/i.match(result) || /^([A-Za-z]+)([A-Z][a-z]+)$/.match(result)) means at a glance.

    While I agree that your code is cleaner to read .underscore is a very expensive method to run in comparison to 2 regular expressions. Considering that pluralize is a heavily used inflection I believe the performance hit is a heavy price in comparison to a comment explaining the regular expressions.
