Layout Question .. (Sitemesh related)

Rails
1

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 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:

Some content

And this is the layout1.rhtml (layout file that t1 gets decorated with):

<%=@content_for_layout%>

Is this possible in rails? If yes, how?

Thanks,
Mufaddal.

Yes - the content is processed before it is passed to the layout, and
you can set instance variables (@xxx) in the content for use in the
layout.

  <!-- can I set a variable show_menu here --> </div>

<% @show_menu = true -%>

(note: the - in front of the %> prevents an empty line being written in
the HTML)

And this is the layout1.rhtml (layout file that t1 gets decorated with):

<% if @show_menu -%>

<% end -%>
<%=@content_for_layout%>
