Question

I have an object in my controller

@data="<meta property=\"og:url\"
             content=\"<%=SITE_URL%><%=request.request_uri%>\"
      />".html_safe

When I print this in my view file by <%=@data%> the html that it generates is

<meta property="og:url" 
      content="<%=SITE_URL%><%=request.request_uri%>"
/>

How do i print out/escape the ruby code withing the string?

Answer 1

You’re looking for string interpolation, which means that in the string, it substitutes the value of the variable. Surround the variables with #{} like this:

@data="<meta property=\"og:url\"
         content=\"#{SITE_URL} #{request.request_uri}\"
  />".html_safe

Now, when you do <%= @data %>, it should show up normally.
