Hi,
I understand that the layout concept is very similar to OpenSymphony''s
Sitemesh project. I have done a lot of development with Sitemesh, but am
fairly new to Rails. I am wondering if there is a way for a layout in
rails to find out value of a variable from a page it is decorating?
In sitemesh you would be able to do <meta name="show_menu"
content="true"> on some page being decorated and then in the layout
page, you can access the value of show_menu using page.getProperty(..)
and can show or hide the menu.
Is there a way to do something like the above in Rails?
For example a template t1.rhtml could be:
<div>
Some content
<!-- can I set a variable show_menu here -->
</div>
And this is the layout1.rhtml (layout file that t1 gets decorated with):
<html>
<head></head>
<body>
<!-- can I use the variable show_menu here that might be defined in the
template this file is decorating -->
<div id=''menu''></div>
<div id=''main''>
<%=@content_for_layout%>
</div>
</body>
</html>
Is this possible in rails? If yes, how?
Thanks,
Mufaddal.

Just found the answer to my post.
If somebody else is looking for an answer to a similar question:
In Rails, layouts have access to all the same data that is available to
conventional templates. Any instance variables set in the normal
template will be available in the layout.
Following my previous example you could do this:
My template file t1.rhtml:
<div>
Some content
<% @show_menu = "true" %>
</div>
And this is the layout1.rhtml (layout file that t1 gets decorated with):
<html>
<head></head>
<body>
<%if @show_menu == "true"%>
<div id=''menu''></div>
<%end%>
<div id=''main''> <%=@content_for_layout%>
</div> </body> </html>
