Is it possible render template without $data param?

[shinriyo]

Hi there.

I always watch sample render method with $data
but, I can't find wihtoout $data param.

            return res.render("src/templates/main.tpl");

is best.
but, render method's 2nd param is not optional

So, I always set dummy data....

            let mut data = HashMap::<&str, &str>::new();
            data.insert("dummy", "dymmy");
            return res.render("src/templates/main.tpl", &data);

However it isn't possible return res.render("src/templates/main.tpl", &[[);

If your template does not need any data, then it's just plain HTML, no? If so, just serve that file statically, res.send_file("path/to/main.html"). Or is there some use case for templates without data that I'm not aware of?

Thank you for replying.
yes, I will render just plain HTML. The template doesn't need &data parameters.
I tried your send_file() method. but, It makes downloading main.html file.

I guess I will use the case is home page(like index.tpl).

I think setting the ContentType header to html should fix this? e.g. response.set(MediaType::Html);

Yep, but it's quite inconvenient. I know I ran into this myself before and we had a discussion on exactly that. Not sure about the right way forward but there should be a simple way to render a template without data, without explicitly setting the MediaType::Html.

Thank you for replying.
I resolved it.

@cburgdorf
Did you discussed about it, didn't you?
yes, I hope simple way.
Or, if Rust language and nickel.rs have slogan, TOOWTD, I give up.
