Rails number_to_currency options

[jesteracer]

I am trying to use number_to_currency helper with :locale option and it works strange
Without r18n gem i get what i want as documented in the rails docs:

helper.number_to_currency(10)
=> "$10.00"
helper.number_to_currency(10, :locale => :ru)
=> "10.00 руб."

But when r18n is used, no matter what i pass in :location option i get the result with the current R18n locale, but not with a locale that i have provided.

So,

helper.number_to_currency(10)
=> "$10.00"
helper.number_to_currency(10, :locale => :ru)
=> "$10.00"
# but when i set it manualy 
R18n.set("ru")
helper.number_to_currency(10)
=> "10.00 руб."

Ps. I need to provide a custom locale to this helper, because it depends on user.locale.

As i tried to understand, why this happens i tested I18n.translate methods (which are used in number_to_currency helper) with and without r18n and got

# With R18n
I18n.translate(:'number.currency.format', :locale => :ru)
=> {:format=>"%u%n", :unit=>"$", :separator=>".", :delimiter=>",", :precision=>2, :significant=>false, :strip_insignificant_zeros=>false}
I18n.translate(:'number.currency.format')
=> {:format=>"%u%n", :unit=>"$", :separator=>".", :delimiter=>",", :precision=>2, :significant=>false, :strip_insignificant_zeros=>false}

# Without R18n
I18n.translate(:'number.currency.format', :locale => :ru)
=> {:delimiter=>" ", :format=>"%n %u", :precision=>2, :separator=>".", :significant=>false, :strip_insignificant_zeros=>false, :unit=>"руб.", :negative_format=>"-%n %u"}
I18n.translate(:'number.currency.format')
=> {:format=>"%u%n", :unit=>"$", :separator=>".", :delimiter=>",", :precision=>2, :significant=>false, :strip_insignificant_zeros=>false, :negative_format=>"-%u%n"}

Then i found, that .translate method in R18n does not support locale option https://github.com/ai/r18n/blob/master/r18n-rails-api/lib/r18n-rails-api/backend.rb but only uses the current locale.

So i am a little bit confused.
What should i do, to get it working?

number_to_currency not working in model. any idea?

[ai]

Oops, I forget to create release :). I release new version after fix #80. You can use git master, just add to Gemfile:

gem 'r18n-core', git: 'git://github.com/ai/r18n.git'

[imran-ashraf-tkxel]

included this in my gem file.
but still getting error.
I want currency up to two precision values only i.e 15.6666666667 to 15.66 but not 15.67.
please share format to be used in my model

Do you run bundle update after add git? Also, can you show me your code?

[imran-ashraf-tkxel]

yea I do bundle update.
here is the code:
amount = number_to_currency(amount, :precision => 2)

I add addition test 00959be and everythings is fine for me. Do you have format instructions in your locale?
