As for the actual problem ;) - I'm pretty sure that req.params["username"] throws a RangeError there (maybe it should be req.form[]?). If you setLogLevel(LogLevel.Debug), you should get a stack trace on the console that gives more certainty.

Still does not work. Here is an example: 

	void defaultHandler(HttpServerRequest req, HttpServerResponse res)
	{
		auto answ = conn.exec("select 12345");
		string cell = answ[0,0].as!PGtext;
		render!("test.dt", req, cell, answ)(res);
	}

extends layout

block content
    h3 this is a form:
    form(method='get')
        fieldset
            legend General
                label(for='username') Username:
                    input( type='text', name='username', value='vasya22' )
                    p #{cell} // done
                    p #{answ[0,0].as!PGtext} // error

cell variable passes to temlate parser, but answ[0,0].as!PGtext causes error:

Compiling diet template 'test.dt'...
test.dt(7): Error: undefined identifier PGtext, did you mean template text(T...)?
test.dt(7): Error: cannot resolve type for (*answ.opIndex(0LU,0LU)).as!(error)
test.dt(7): Error: template vibe.templ.diet.toString does not match any function template declaration
diet.d(912): Error: template vibe.templ.diet.toString(T) cannot deduce template function from argument types !()(error)

(answ[0,0].as!PGtext is actually a string type)

Apparently, I do not understand what types of variables supports templates parser. It would be convenient to show result of sql query in the template, but at the moment I can't.
