How do I internationalize/localize my rails plugin?

Rails

I wrote a validates_word_count plugin. I would like to store the error
messages in a YAML file so they can be easily translated.

Full source:
GitHub - paulschreiber/validates_word_count: rails validation plugin. validates word count for a block of text.

My plugin’s file layout looks like this:
validates_word_count/
init.rb
lib/
validates_word_count.rb
locale/
en.yml

My YAML file looks like this:
en:
validates_word_count:
errors:
messages:
too_few_words: “has too few words (minimum is %d words)”
too_many_words: "has too many words (maximum is %d words)

However, if I call
I18n.translate(‘validates_word_count.errors.messages.too_few_words’),
I get this error:
translation missing: en, validates_word_count, errors, messages,
too_few_words

How can I set up my plugin / locale so I18n.translate() works?

You’ll note that it follows the Rails convention of having a config
and config/locales directory.

Hope that helps,

Unfortunately, it does not. I tried this layout:

validates_word_count/
init.rb
lib/
validates_word_count.rb
config
locales/
en.yml

And I still get the “translation missing” error.

Yes, but did you add your locales directory to the load path as in
init.rb file I linked to? That part is the missing step.

Using the convention of Rails is not enough, you have to tell Rails to
include files in the directory.

Success.

I heard back from Paul that that last bit did the trick.
