I create a simple .rhtml file "hello.rhtml" in the "view"
folder of the
rails app.
<html>
<head>
<title>Hello World</title>
</head>
<body>
<p>Hello World!</p>
<p><%= ''Hello Dynamic World'' %></p>
</body>
</html>
The problem is when I run the web server and load the url
"http://localhost:3000/say/hello", only "Hello World!" is
shown, the
second line ''Hello Dynamic World'' is gone?
Anyone can help me? Thanks very very very much!

Thanks very very very much!What does your generated HTML look like? What''s in your application log?

<font size="-1"><font face="Helvetica, Arial,
sans-serif">.rhtml works
fine at least through 2.2.2. .html.erb may be the way to go but .rhtml
is not the problem. The problem is what do you expect a string to do?
<%= %> says to evaluate the ruby expression and then return the
result. I think the code should be something like <%= p
''whatever''
%>. <br>
<br>
Am I loosing my mind?<br>

Thanks for your information, Marnen Laibow-Koser My rails is 2.3.4, I change the file "hello.rhtml" to "hello.html.erb" But the browser still just show the first line, and doesn''t show anything inside <%= XXX %>, do I miss something?

Some versions of Rails have been confused by these. Temporarily remove hello.html.erb and make sure that it then complains it cannot find the file. This will make sure it is picking up the right one. What does the generated html look like (View, Page Source or similar in browser)? Post the relevant section here.

It works !!! Thanks very very much for Colin ^^ I temporarily remove hello.html.erb and the browser show the error message "Missing template say/hello.erb in view path app/views" So I change file name to hello.erb, and the ruby code inside <%= %> works!

Hello, Marnen Laibow-Koser I run C:\Documents and Settings\brownylin\rails\my_app>rake routes and the results are shown below three lines: (in C:/Documents and Settings/brownylin/rails/my_app) /:controller/:action/:id /:controller/:action/:id(.:format) What does the routing problem mean? And what dose the three line output means? Many many thanks for Marnen Laibow-Koser ^^ Marnen Laibow-Koser wrote:> Browny Lin wrote: >> >> It works !!!

I''m not sure you''d be able to get say/hello to work with just these routes. I assume you have an action called hello in your SaysController class?> > What does the routing problem mean?
