Extension to ember-i18n for translating error messages within the route hierarchy

Ember-i18n-errors

This addon leverages ember-i18n but for the specific purpose of localize error messages.

It adds to your app a handy helper {{t-error error}} for translating errors in the context of the current route, but also takes advantage of Ember's route nesting to lookup translations in fallback on parent routes.

Installation

This addon requires Ember.js 1.13+ and ember-i18n 4.1+

• ember install ember-i18n-errors

Usage

This is better explained with an example.

Let's say we have a validation error with the mandatory shape ({ attribute: 'email', message: 'invalid' }) and some nested routes with this structure:

parent
└── child
    └── grandchild

If within the grandchild.hbs template we use the helper {{t-error error}} the helper will try to find the most especific translation key for it based on the route hierarchy.

It follows a set of conventions very similar to how rails-i18n handles ActiveRecord errors.

The fallback chain for that error will be:

parent.child.grandchild.errors.email.invalid
parent.child.grandchild.errors.invalid
parent.child.errors.email.invalid
parent.child.errors.invalid
parent.errors.email.invalid
parent.errors.invalid
errors.email.invalid
errors.invalid

If none of those keys is defined in your translations the missing translation message will point you to the most specific translation: Missing translation: parent.child.grandchild.errors.email.invalid.
