回答1:

This is an i18n (internationalization) issue, where it needs to know what yoru locale is. Specify the default locale for your internationalization in your config/application.rb file

config.i18n.default_locale = :en

or perhaps you want Slovak

config.i18n.default_locale = :sk

EDIT

You can also specify the locale when you call the confirmation_url method...

<p><%= link_to _('Confirm my account'), confirmation_url(@resource, confirmation_token: @token, locale: 'en') %></p>
