Javascript Include Tag Best Practice in a Rails Application

Question

Say I need to call a javascript file in the of an ERb template. My instinct is to do the usual:

<%= javascript_incl         


        

Answer 1

I usually have the following in the layout file:

  <%= javascript_include_tag :defaults %> 
  <%= @extra_head_content %>

And then in the views:

<% (@extra_head_content ||= "") += capture do %>
  <%= other_content %>
<% end %>

See the API documentation for #capture
