Hi All,  
I have a string variable that contains other ruby  
variables. I intend to render the string variable and replace the  
other ruby variables in it with their values.Is it possible?

To clarify my question, here is the same :-

@ruby\_variable = “Some value in the variable”

@variable\_to\_be\_rendered = “Some text @ruby\_variable”

After rendering(if thats possible, or some other function), I would  
get the value

“Some text Some value in the variable”

Regards,  
Mohit

yes, you can use erb for that

[http://www.ruby-doc.org/core/classes/ERB.html](http://www.ruby-doc.org/core/classes/ERB.html)

> @variable\_to\_be\_rendered = “Some text @ruby\_variable”

would have to look like:

@variable\_to\_be\_rendered = “Some text \<%= @ruby\_variable %\>”

to do that

Cool! It works like a charm :-).

Is there any thing similar in rails, rather than ruby?
