= ContentFor
|
||||
|
||||
Small extension for the Sinatra[http://sinatrarb.com] web framework
|
||||
that allows you to use the following helpers in your views:
|
||||
|
||||
<% content_for :some_key do %>
|
||||
<chunk of="html">...</chunk>
|
||||
<% end %>
|
||||
|
||||
<% yield_content :some_key %>
|
||||
|
||||
This allows you to capture blocks inside views to be rendered later
|
||||
in this request. For example, to populate different parts of your
|
||||
layout from your view.
|
||||
|
||||
When using this with the Haml rendering engine, you should do the
|
||||
following:
|
||||
|
||||
- content_for :some_key do
|
||||
%chunk{ :of => "html" } ...
|
||||
|
||||
= yield_content :some_key
|
||||
|
||||
<b>Note</b> that with ERB <tt>yield_content</tt> is called <b>without</b>
|
||||
an '=' block (<tt><%= %></tt>), but with Haml it uses <tt>= yield_content</tt>.
|
||||
|
||||
Using an '=' block in ERB will output the content twice for each block,
|
||||
so if you have problems with that, make sure to check for this.
|
||||
|
||||
== Usage
|
||||
|
||||
If you're writing "classic" style apps, then requring
|
||||
<tt>sinatra/content_for</tt> should be enough. If you're writing
|
||||
"classy" apps, then you also need to call
|
||||
<tt>helpers Sinatra::ContentFor</tt> in your app definition.
|
||||
|
||||
== And how is this useful?
|
||||
|
||||
For example, some of your views might need a few javascript tags and
|
||||
stylesheets, but you don't want to force this files in all your pages.
|
||||
Then you can put <tt><% yield_content :scripts_and_styles %></tt> on
|
||||
your layout, inside the <head> tag, and each view can call
|
||||
<tt>content_for</tt> setting the appropriate set of tags that should
|
||||
be added to the layout.
