liquid + i18n from rails

gistfile1.rb

# lib/liquid_i18n_rails.rb
module LiquidI18nRails
  def t(string)
    I18n.t(string.to_sym)
  end
end

# config/initializers/liquid.rb
require 'liquid_i18n_rails'
Liquid::Template.register_filter LiquidI18nRails

# and then:
{{ 'string' | t }}
# where 'string' is name of sym for I18n.t
# it will do .to_sym automatically

@phlegx I18n.l

Thanks! this was super helpful in connecting the filter to the I18n API.

I found that our translations needed to be able to do interpolation, so I expanded this class to allow it to be used like {{ 'fundraiser.donate' | val: 'amount', my_amount | t }}. I also edited it to raise errors in development when a liquid template is rendered with missing translations. I've added a gist of it with a spec in another gist.

I couldn't find anything on liquid for translations with arguments so I did something like this

module LiquidI18nRails
  def t(string, arguments = nil)
    I18n.t(string.to_sym, arguments.with_indifferent_access)
  end
end

now can translate it like this

{{ 'hello.world' | t: data: 'yourname' }}
