The redirect is working fine with IntelliJ and redirects to the path "/" with the title refreshing with the passed in username. I'm lost as to what I am doing wrong.
package com.teamtreehouse.courses;
import com.teamtreehouse.courses.model.CourseIdea;

public class Main {
public static void main(String[] args) {
staticFileLocation("/public");
CourseIdeaDAO dao = new SimpleCourseIdeaDAO(); //This SimpleCourseIeaDAO is not meant for production. Just a prototype. Should be linked to a DB
get("/", (req, res) -> {
Map<String, String> model = new HashMap<>();
model.put("username", req.cookie("username"));
return new ModelAndView(model, "index.hbs");
}, new HandlebarsTemplateEngine());
// Replaces previous post request. This one redirects to main page.
post("/", (req, res) -> {
String username = req.queryParams("username");
res.cookie("username", username);
res.redirect("/");
return null;
});
get("/ideas", (req, res) -> {
Map<String, Object> model = new HashMap<>();
model.put("ideas", dao.findAll());
return new ModelAndView(model, "ideas.hbs");
}, new HandlebarsTemplateEngine());
post("/ideas", (req, res) -> {
String title = req.queryParams("title");
//TODO:nfa - This username is tied to the cookie. Problem: only way to know user is logged in is by cookie
CourseIdea courseIdea = new CourseIdea(title,
req.cookie("username"));
dao.add(courseIdea);
res.redirect("/ideas");
return null;
});
}
}

25,764 PointsIt wasn't producing any 404 error in IntelliJ because I changed the form's action to "/" in index.hbs . But without changing the HTML, I would indeed have to leave the route as /sign-in. It is solved now.
Thank you so much for the help!
