Brian, unfortunately these settings have any effect on string to float
conversion performed by the validators.
Take a look at these methods from Rails 3 beta 4:
def parse_raw_value_as_a_number(raw_value)
case raw_value
when /\A0[xX]/
nil
else
begin
Kernel.Float(raw_value)
rescue ArgumentError, TypeError
nil
end
end
end
def parse_raw_value_as_an_integer(raw_value)
raw_value.to_i if raw_value.to_s =~ /\A[+-]?\d+\Z/
end
The locale support you are talking about is only related to number
helpers like those you have mentioned...
I'm talking about extending this notion of locale support for numbers.

Hi Rodrigo,
I think the proper way to do this is to override those formats in your
translation yaml files (config/locales). For reference of what the
keys are take a look at
http://github.com/rails/rails/blob/master/actionpack/lib/action_view/locale/en.yml#L7-9
You'll notice that those I18n keys are used in the number helpers like
in `number_with_delimiter` here:
http://github.com/rails/rails/blob/master/actionpack/lib/action_view/helpers/number_helper.rb#L209
You'll have to create a file like `config/locales/pt-BR.yml` and at
the very least add those number I18n keys for separator and delimiter.

What is the suggested path for dealing with number formats in Rails?
Even if we set locale to pt-BR, for instance, if the user inputs a
number like '1.000,00' or '1000,00' in a form input, numerical
validation will yield an 'invalid_number' error, even though this is
a valid format in Brazil.
I could monkey patch overriding parse_raw_value_as_a_number to
replace '.' with '' and ',' with '.' in
ActiveModel::Validations::NumericalityValidator but that wouldn't
solve the problem because the application is internationalized. So,
even if I monkey patch this method, I would have to take into
consideration the current user locale before parsing the number...
Are there any plans for supporting this on Rails 3?
