Re: [Cppcms-users] render sub-template without parents

[Artyom B. <art...@ya...>]

Think this

you have a template that generates some interesting content


<% view some_view uses page_content %>
<% template page_content() %>
...
<% end template %>
<% end view %>

Lets derive a new template

<% view page_content_only uses page_content extends some_view %>

<% template render() %>
<% include page_content() %>
<% end template %>
<% end view %>


Now you can render "page_content_only" view that would create what you need.

{
   ...
   render("page_content_only",c);
   ...
}

Thinks of classes and inheritance. 

You can also use "helpers" concept and generate a separate view that only
generates a page_content and use it in various places:
