How to concatenate I18n.t() strings in content_for() helper?

I'd like to concatenate the strings from my localization file "admin.titles.index" and "%{model_name}" (which takes from activerecord.models.harddisk).

I tried with:

<% title = I18n.t("admin.titles.index") + I18n.t("%{model_name}", 
           model_name: admin.model_name, 
           pluralized_model_name: admin.model_name.pluralize)%>

<% content_for(:title, title) %>

But I get an error message: 

translation missing: de.%{model_name}

How can I fix that?

You need to provide a translation for a string, that you pass in I18n.t. As long as you don't have a translation for "%{model_name}" you'll get the error message.

In your case, you can just concatenate the string from localization with your model name:

<% title = I18n.t("admin.titles.index") + admin.model_name %>

Otherwise, you need to provide a translation for model_name in yml file. For example:

en:
  model_name: "English %{model_name}"
de:
  model_name: "German %{model_name}"

and then use it as

I18n.t("admin.titles.index") + I18n.t("model_name", model_name: admin.model_name)
