Incorrect inflectors for 'business' or '*ness'

Reported by Paulo Pereira | April 2nd, 2009 @ 11:24 AM | in 2.x

Hi there.

I'm using activesupport 2.3.2, and found a simple inflector error.

>> require "activesupport"
=> true
>> "business".singularize
=> "busines"
>> "madness".singularize
=> "madnes"

But plurals and handled nicely.

>> "business".pluralize
=> "businesses"
>> "madness".pluralize
=> "madnesses"

    • Tag set to activesupport, inflections, inflector

    Paulo you're right. I've found that singular words ending in 'ess' like:

    business, address, express, dress, press

    are singularized wrongly since the current inflections do not contain a proper rule. I propose to include such rule, that you can find attached along with tests.


    Before patch

    "address".singularize => "addres" "address".classify => "Addres"

    After patch "Address"

    "address".singularize => "address" "address".classify => "Address"

    1. Address is a quite common case and patch works.

    • State changed from “new” to “wontfix”

    Rails has a longstanding policy of not taking further inflector patches. Use an initializer in your application instead.

    Hello Mike,
    thank you for your response. In case of erratic behaviour of the inflector,
    that's enough to add a rule to the inflector initializer and stay neat and
    Just for clarity, the problem raised by Paulo will be solved by adding the

    ActiveSupport::Inflector.inflections do |inflect|

    inflect.singular(/ess$/i, 'ess')


    to the file:


    Thank you.

    • Tag cleared.
    • Importance changed from “” to “Low”

    Automatic cleanup of spam.

    Another workaround. Instead of:

    s = 'Address'
    s.singularize # 'Addres'


    s = 'Address'
    s.pluralize.singularize # 'Address'

    Note that this affects the behaviour of .classify as well, but still s.pluralize.classify will work around it.

    In ticket #6057, Andrés Mejía asked:

    "Rails has a longstanding policy of not taking further inflector patches."

    May I ask what is the reason behind this?

    I'd also like to know the answer for this. I can imagine that patches tend to break other cases, so maybe that's the reason. But for such a long-standing problem that affects Rails 2.3.x and 3.x, I'm surprised to still see this as an issue.
