问题描述
当我执行console.log(comments)
时,它会打印注释ID;当我执行console.log(post.comments.text)
时,它会显示undefined
。但是,注释已成功保存在数据库中,并且
// COMMENT FUNCTION
router.post("/:id/comments",middleware.isLoggedIn,function(req,res) {
//look up for post using id
Post.findById(req.params.id,function(err,post) {
if (err) {
console.log(err);
req.flash("error","something went wrong")
res.redirect("/posts");
} else {
//Create comment
req.body.comment.body = req.sanitize(req.body.comment.body);
Comment.create(req.body.comment,comment) {
if (err) {
console.log(err);
req.flash("error","OOPS! something went wronng")
} else {
//add username and id to comment
comment.author.id = req.user._id;
comment.author.username = req.user.username;
comment.save();
post.comments.push(comment);
post.save();
console.log(post.comments.text);
req.flash("success","Comment added successfully");
res.redirect("/posts/" + post._id);
//console.log("comment is saved");
}
});
}
});
});
