Browser can't display the ruby part in rhtml

rubyonrails-talk

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&quot;, only "Hello World!" is shown, the second line 'Hello Dynamic World' is gone?

Anyone can help me? Thanks very very very much!

Ack! Didn't notice this when posting the first time around...if you're using Rails 2.x, that should be hello.html.erb . If your tutorial is using the .rhtml extension, then it's out of date and you should follow another tutorial.

.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’ %>.

Am I loosing my mind?

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?

Make sure you have not got any other files hello.* in the view folder (backup files for example). 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!

Then you have a routing problem. What's the output if you type "rake routes" at the command line?

Many thanks again

Best,
