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,
<html>
<head>
<title>All Recipes</title>
</head>
<body>
<ul>
<li>Addition: <% print "World!" %> </li>
</ul>
<h1>Online Cookbook - All Recipes</h1>
</body>
</html>
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 %> Fred> <html> > <head> > <title>All Recipes</title> > </head> > <body> > <ul> > <li>Addition: <% print "World!" %> </li> > </ul> > <h1>Online Cookbook - All Recipes</h1> > </body> > </html> > > 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 > -- > Posted via http://www.ruby-forum.com/. > > >--~--~---------~--~----~------------~-------~--~----~ You received this message because you are subscribed to the Google Groups "Ruby on Rails: Talk" group.

Shrikant, <% %> is code that is executed, but not displayed in the browser. <%= %> is code that will be executed and displayed. Hope that helps!
