Hi all. I have a custom validation which produces an error message with dynamic content, like so: errors.add\_to\_base(“Must have exactly #{self.size} questions for a #{self.size}-question sequenced quiz”) Can anyone tell me the cleanest way to localise this? I can think of some dirty sort of ways along the lines of errors.add\_to\_base("#{I18n.t(:‘quiz.errors.sequential.wrong\_question\_number\_1’)} #{self.size} #{I18n.t(:‘quiz.errors.sequential.wrong\_question\_number\_2’)} #{self.size} #{I18n.t(:‘quiz.errors.sequential.wrong\_question\_number\_3’)}") But this seems nasty like i say, and also assumes that in all languages there will be three text chunks with the size in between, which might not be the case. Can i somehow incorporate variables into my locale.yml files? or some other similar approach? ---

So you can pass variables into the .yml file then? (tries it…) Hmm, i just get the string without the interpolation: eg, trying it with a simple example, just called from the view template rather than a model validation: #in template = t(:‘quiz.attributes.description’, :size =\> “#{@quiz.size}”) #in .config/locales/en.yml quiz: attributes: description: “Description for your #{size} question quiz” #rendered out Description for your #{size} question quiz Do i need to change my setup to enable this variable-passing? I’m just using all of the basic I18n in rails 2.3.4. thanks, max ---

You have to change this: t(:‘quiz.attributes.description’, :size =\> @quiz.size) In the view you pass the varible without direct to hash. 2010/3/26 Max W.

Thanks Andres, but that gives the same result. = t(:‘quiz.attributes.description’, :size =\> @quiz.size) gives Description for your #{size} question quiz Surely it wouldn’t make any difference anyway? The string interpolation would happen before the t method is called, right? So it would just be like passing a string through. And if it can take integers dynamically then surely it can take strings dynamically. Seems my problem is that it’s not taking anything dynamically. ---

Solved it: This part of the I18n documentation showed me how: > **[Rails Internationalization (I18n) API — Ruby on Rails Guides](https://guides.rubyonrails.org/i18n.html#interpolation)** > > Rails Internationalization (I18n) APIThe Ruby I18n (shorthand for internationalization) gem which is shipped with Ruby on Rails (starting from Rails 2.2) provides an easy-to-use and extensible framework for translating your application to a single... The problem was the syntax for string interpolation in the .yml file. You _don’t_ do this: ``` description: "Description for your #{size} question quiz" ``` But instead, do this: ``` description: "Description for your {{size}} question quiz" ``` Thanks all. Max ---
