when i studied the tutorial about layouts & content\_for from railscast.I  
need a clarification as per their tutorial.

url:[#8 Layouts and content\_for - RailsCasts](http://railscasts.com/episodes/8-layouts-and-content-for)

\<!- projects/index.rhtml →   
\<% content\_for :head do %\> \<= stylesheet\_link\_tag ‘projects’ %\>  
\< end %\>

\<!- layouts/application.rhtml →

 Todo List \<%= stylesheet\_link\_tag ‘application’ %\> \<%= yield :head %\>

As per the tutorial they are calling the yiel:head & content\_for :head  
has been written in index.html.erb.

My question is if i want to call another yield such as yield :footer and  
if i write content\_for :footer in some other file like footer.html.erb.  
Then in my layout yield :footer is not taking.

Please give me some suggestions regarding this

Thanks in advance

You have to keep in mind how views are being called:

- The browser makes a request to a URL
- The Rails routing rules determine which controller/action the URL  
resolves to
- The action is called
- The corresponding view (assuming the action doesn’t redirect to a  
new action) is being called
- The controller (usually) determines which layout is to be used
- The view is displayed together with the layout.

So: if you have an index.html.erb view being displayed, together with  
the layout application.html.erb, that’s all that will be displayed. If  
your view doesn’t define content\_for for all the parts listed in you  
layout (with yield), those symbols remain undefined (nil) and don’t  
display. Which is why your :footer part isn’t displayed, there is  
nothing telling rails to display the footer.html.erb template.

If you want to render a footer partial, you can use \<%=  
render :partial =\> shared/footer %\> for example. That will actually  
include the shared/\_footer.html.erb template in your page.
