Ruby on Rails - embed additional HTML inside of link_to call that includes I18n

问题

I am trying to embed additional HTML inside of a link_to call as found in this thread Embed additional HTML inside of link_to call

However, I would also like to use I18n. So instead of this:

 <%= link_to '<i class="icon-search"></i> Show'.html_safe, exercise_path(exercise), :class => 'btn btn-small' %>

I would like to use t(:show) or I18n.t(:show) instead of a hardcoded Show in the above example. I am having trouble figuring out the correct syntax, though. Any help would be greatly appreciated.

回答1:

There's an easier/cleaner way to embed additional items into a link_to by using its block syntax. E.x.

<%= link_to exercise_path(exercise), :class => 'btn btn-small' do %>
  <i class="icon-search"></i>
  <%= t(:show).html_safe %>
<% end %>

回答2:

Use raw function just like below example

<%= link_to raw("<i class='icon-search'>some italic text </i> #{t(:show)}"), exercise_path(exercise), :class => 'btn btn-small' %>

回答3:

<%= link_to "<i class='icon-search'></i> #{t(:show)}".html_safe, exercise_path(exercise), :class => 'btn btn-small' %>

Use #{} to embed ruby code in strings.
