How to Render MVC Template?

[niko...@brightminds.org]

Hello,

I am using Jooby 2.9.6 and Handlebars.java.

I am trying to render a template to a string so that I can send it as an email yet I cannot seem to find the way to do this.

ModelAndView mvc = new ModelAndView("email_template.hbs");

...

String html = mvc.render()?????

I have found TemplateEngine and MessageEncoder but cannot seem to figure out how to get an instance to be able to render to a string.

This should be so simple... and knowing Jooby probably is ;-)

Hello,

Does anyone have a suggestion?  I am sure I am missing something really basic....

I love Jooby and hope others who are using it can assist.

Thank You,

Hi,

if you read the docs:  jooby/HandlebarsModule.java at 2.x · jooby-project/jooby · GitHub

it tells you you can get an instance by:

Handlebars hbs = require(Handlebars.class);

And in the source of: jooby/HbsTemplateEngine.java at 2.x · jooby-project/jooby · GitHub

you can see that rendering something can be done by something like this:

@Override public String render(Context ctx, ModelAndView modelAndView) throws Exception {
Template template = handlebars.compile(modelAndView.getView());
Map<String, Object> model = new HashMap<>(ctx.getAttributes());
model.putAll(modelAndView.getModel());
return template.apply(model);
}

regards,

Istvan
