How can I display a translation of a database column name as a table heading in a view, Rails 3

Question

I have a model called User with an attribute called current_sign_in_at. In my en.yml file I have the display name as such…

en-GB:
  activerecord:
    attributes:
      user:
        current_sign_in_at: "Last sign-in"

…which allows me to display the desired form label ("Last sign-in") using = f.label :current_sign_in_at.

But how can I use this same translation for a table header, i.e. not in a form?

%th= :current_sign_in_at

Answer 1

You can use the static method "human_attribute_name", See the doc here on API dock

In your case:

%th= User.human_attribute_name :current_sign_in_at

(use User.human_name to display the model name translated with I18n in en.activerecord.models.user)

Hope this helps!

Answer 2

Another option for internationalized table headings is the table_for gem.

This will let you write erb code like:

<%= table_for @user do |table| %>
  <% table.column :current_sign_in_at %>
<% end %>
