I’m trying to replicate the Snippet functionality in typical CMSs. I  
have a table called “Pages” and “Snippets”, where the latter is inserted  
into the former.

I want the @page.body to replace anything between these tags {{ }} with  
its appropriate snippet title (e.g., {{ Footer }}).

I’m thinking something along the lines of:

\<%=h @page.body.gsub(“ANYTHING\_BETWEEN\_{{\_}}\_TAGS”,  
Snippet.find\_by\_title(“APPROPRIATE\_SNIPPET\_TITLE\_HERE”).body ) %\>

Any ideas?

I’d go with something like this:

class Page  
def processed\_body  
body.gsub(/{{(.+?)}}/) do  
snippet = Snippet.find\_by\_title($1)  
snippet ? snippet.body : “could not find snippet: #{$1}”  
end  
end  
end

Then in your view you can use:  
@page.processed\_body
