Play 2.1 Scala: Render template from string

[Eneko Alonso]

How can I render a template from a string? For example, if I load a template from a database table, how can I compile it on the fly and render it?

Thanks,

Eneko

Probably hard if not impossible with the Scala templates.  

In case you would consider alternate template engine, I added the support to Japid42 (https://github.com/branaway/japid42) yesterday, so one can do something like the following in a controller:

public static Result dynamic() {

String template = "@(String s, int i)\nHi ${s}, are you ${i} years old?";

return ok(renderDynamic(template, "Johnny", 13));

}

The dynamic inline script is compiled to jvm bytecode and cached. It can use whatever other templates (tags, etc) on your harddrive.  

Remember though, the dynamic scripts must be managed in your hands, or you risk exposing the runtime system to attackers.

Do you really want to compile the templates on the fly? How are these templates generated?

Well one possible way would be to compile the template to scala using the ScalaTemplateCompiler.compile. But I would like to understand the usecase better
