How to let the layout be more OO?


#1

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

units. I hope there exists a kind of way that:
<%= if condition1 %>
<%= @content_for_view1 %>
<%= if condition2 %>
<%= @content_for_view2 %>
....

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