Unused keys and controllers in modules

[atipugin]

There is a problem with keys in controllers that nested in modules. For example:

$ be i18n-tasks health
Forest (ru) has 99 keys in total. On average, values are 27 characters long, keys have 3.4 segments.
✓ Perfect! No translations are missing.
Unused keys (3) | i18n-tasks v0.7.11
+--------+-----------------------------------+-----------------------------+
| Locale | Key                               | Value                       |
+--------+-----------------------------------+-----------------------------+
|   ru   | projects.campaigns.create.notice  | Кампания успешно создана.   |
|   ru   | projects.campaigns.destroy.notice | Кампания успешно удалена.   |
|   ru   | projects.campaigns.update.notice  | Кампания успешно сохранена. |
+--------+-----------------------------------+-----------------------------+

relative_roots option is set to:

relative_roots:
    - app/views
    - app/controllers

Controllers look like this:

module Projects
  class CampaignsController < BaseController
    # ...

    def create
      @campaign = @project.campaigns.new(campaign_params)
      authorize(@campaign)
      if @campaign.save
        redirect_to project_campaign_path(@project, @campaign),
                    notice: t('.notice')
      else
        render :new
      end
    end

    # ...
end
