You forgot to add the =
in the ERB tab. It won't echo to the page without that. It should look like this:
<%= f.input :current_password, :label => "Contraseña Actual" %>
Keep in mind, statements whose values you do not want to show on the page should omit the equals (=
) sign. Examples of those statements would be things like <% if ... %>
, <% @some_var.each do .... %>
etc.
Values you do wish to appear on the page, such as your input line, should have the equals sign.
