I assume the new HandlebarsTemplateEngine is to no longer be used.... and we are to redirect to '/'.....how can I view my syntax errors? There is no 'Preview' button or tab....
package com.teamtreehouse.courses;
import com.teamtreehouse.courses.model.CourseIdea;
import com.teamtreehouse.courses.model.CourseIdeaDAO;
import com.teamtreehouse.courses.model.SimpleCourseIdeaDAO;
import spark.ModelAndView;
import java.util.HashMap;
import java.util.Map;
import static spark.Spark.*;
public class Main {
public static void main(String[] args) {
staticFileLocation("/public");
CourseIdeaDAO dao = new SimpleCourseIdeaDAO();
get("/", (req, res) -> {
Map<String, String> model = new HashMap<>();
model.put("username", req.cookie("username"));
return new ModelAndView(model, "index.hbs");
};
post("/sign-in", (req, res) -> {
Map<String, String> model = new HashMap<>();
String username = req.queryParams("username");
res.cookie("username", username);
model.put("username", username);
return new ModelAndView(model, "sign-in.hbs")
};
get("/ideas", (req, res) -> {
Map<String, Object> model = new HashMap<>();
model.put("ideas", dao.findAll());
return new ModelAndView(model, "ideas.hbs");
};
post("/ideas", (req, res) -> {
String title = req.queryParams("title");
// TODO:csd - This username is tied to the cookie implementation
CourseIdea courseIdea = new CourseIdea(title,
req.cookie("username"));
dao.add(courseIdea);
res.redirect("/");
return null;
});
}
}

23,732 PointsIt looks pretty much like the other redirect that you have in your code. No need for HandlebarsTemplateEngine or returning a new ModelAndView:
post("/sign-in", (req, res) -> {
Map<String, String> model = new HashMap<>();
String username = req.queryParams("username");
res.cookie("username", username);
res.redirect("/");
return null;
});
