I18n for model-specific Rails submit button

问题

I've found that Rails allows for generic i18n of submit buttons via the following in config/locales/en.yml:

en:
  helpers:
    submit:
      create: "Create %{model}"
      submit: "Save %{model}"
      update: "Update %{model}"

However, I'm looking to update the create value only for one specific model. I'd like the text to read as "Upload %{model}" or just "Upload". How can I make this change for just one model (e.g.: a Photo model)?

From the source code, it looks like you should be able to do this:

en:
  helpers:
    submit:
      post:
        create: "Upload %{model}"

where post is the name of your model. The inline docs also mention that you can do this.

If you use the i18n-debug gem, the rails server will print translations look-up attempts to the console, like:

[i18n-debug] en.helpers.submit.post.create => nil
