Hi everyone,

I am a newbie to RoR. I installed the Instant Rails package 1.7, and  
with scaffold, I was able to create and connect to a database.  
However, when I embed some code in rhtml(list.rhtml in the tutorial  
there), it does not display in browser. I can see the html part on the  
screen without problem, but the ruby part does not get processed at all.  
When I try a simple rhtml file such as below,

All Recipes
- Addition: \<% print "World!" %\> 

# Online Cookbook - All Recipes

all I can see is  
Addition:  
Online Cookbook.

I think this has something to do with eruby or erb, but do not know how  
to proceed.

Any help would be much appreciated!

Thanks  
Shrikant

You need to be using \<%= which inserts the result of evaluating it’s  
contents, ie \<%= Time.now %\>

Shrikant,

\<% %\> is code that is executed, but not displayed in the browser.  
\<%= %\> is code that will be executed and displayed.

Hope that helps!

Just an example of both usages

\<% if is\_admin? do %\>

# \<%= admin\_title %\>
\<% end %\>
