I've got the following problem: I have rhtml (html minced together with ruby inside <% %> and <%= %> tags) stored in a database which I want to render. The information is acquired through a query. I need to be able to evaluate the information I get from the database as though as it was normal content inside the .erb-file. What I currently have:

<% @mymods.each do |mod| %>
<%=  render_text(mod["html"])%>
<% end %>

Where mod["html"] is the variable containing the rhtml-code and @mymods an array of objects from the query. I have currently no idea what function I should use (render_text does, of course, not work).

Help is greatly appreciated.
