hobo_translate / ht
Wrapper around the Rails :translate helper with hobo added features.
It can be used as a regular helper or as a dryml tag.
Hobo Added Features
The first part of the key must be a model name (e.g.: user.index.title -> user). This method will add a "model" interpolation variable set to the translated and pluralized Model.model_name.human. Besides, it will add a default 'hobo.' fallback, (e.g.: hobo.index.title) at the beginning of the fallback chain.
You can also pass any other :translate option like for example :count.
Example:
<%= ht :key=>'user.index.title', :default=>'Index' %>
<ht key="user.index.title">Index</ht>
#=> "Index" # if "user.index.title" or "hobo.index.title" is not found
#=> "User Index" # with the below en.yml file
=== en.yml ===
en:
hobo:
index:
title: %{model} Index
