LISTING OWNER

 EVERY LISTING IS ASSIGNED AN OWNER TO AUTHORIZE THE LISTING INORDER TO EDIT/ DELETE THE LISTING.

BEFORE AUTHORIZATION OWNER FIELD IS ADDED TO THE USER SCHEMA AND IS INITIALIZED IN THE DATABASE.

IN init FOLDER INDEX.JS

const initDB = async () => {

  await Listing.deleteMany({});

 initData.data= initData.data.map((obj) => ({ ...obj, owner: "67d42a6d78000309d98682f2" }));

  await Listing.insertMany(initData.data);

};

initDB();

{ ...obj, owner:

...obj TO GET THE EXISTING  DATA IN obj

LISTINGS.JS

// SHOW ROUTE

router.get(

  "/:id",

  wrapAsync(async (req, res) => {

    let { id } = req.params;

    const listing = await Listing.findById(id)

      .populate("reviews")

      .populate("owner");

    if (!listing) {

      req.flash("error", "Listing requested doesn't exist!");

      res.redirect("/listings");

    }

    res.render("listings/show.ejs", { listing });

  })

);
