Rails - Mar 2006 - How to let the layout be more OO?

I am confused about the @content_for_layout.''cause it will display all 
the views in the layout.Do I have any methods to let the layout be more 
OO? I mean that for example,the app currently have more than one views 
to be displayed,but only some of them to be displayed at the same time 
at different <div></div> units. I hope there exists a kind of way
that:
 <%= if condition1 %>
 <div id=''condition1''>
    <%= @content_for_view1 %>
 </div>
 <%= if condition2 %>
 <div id=''condition2''>
    <%= @content_for_view2 %>
 </div>
....

How to reach such an aim in rails? I am a newbie. very grateful!

Hi,

I encountered the same issue.  I''m sure there are better ways to do
this, and perhaps some even "blessed" ways, but here is what I did.

In my application controller, I added the following:

  before_filter :render_sidebars

  private

  def render_sidebars
    @left_sidebar_for_layout = render_to_string(:partial =>
''shared/left_sidebar'')
    @right_sidebar_for_layout = render_to_string(:partial =>
''shared/right_sidebar'')
  end

Then, in my application layout, I use these new content variables the
same as I would for @content_for_layout.

It''s not pretty, but it works.

Anyone got a better way?

Thanks,
  Brad

Hi,

I am just about to launch into something similar.  One thing that I have
been thinking of (but havn''t had time to try yet) is to use the
content_for
method.

Using Techno-weenie''s acts_as_authenticated as a guide, the index page
contains the following

<%% content_for ''poem'' do -%>
...
some text in here
...
<%%= simple_format @content_for_poem %>

I''m not sure why there is %% in there but it works.

What my thinking is that in your view you could include many of these
content_for ''name'' functions
that would then be rendered in your layout.

The doc is available at
http://api.rubyonrails.org/classes/ActionView/Helpers/CaptureHelper.html#M000450

This is then available to your layouts as <%= @content_for_name %>

I hope this works..  I''m going to be trying it soon :)

Cheers
Dan
