javascript - How to make POST work using router.post in Express JS -

-

i'm new , i'm following tutorial. app creating posts , comments posts. i've created post creating posts, can't post comments work. have 2 models:

var post = mongoose.model('post'); var comment = mongoose.model('comment');

posts model

var mongoose = require('mongoose');  var postschema = new mongoose.schema({     title: string,     link: string,     upvotes: {         type: number,         default: 0     },     comments: [{         type: mongoose.schema.types.objectid,         ref: 'comment'     }] });  postschema.methods.upvote = function (cb) {     this.upvotes += 1;     this.save(cb); };  mongoose.model('post', postschema);

comments model

var mongoose = require('mongoose');  var commentschema = new mongoose.schema({     body: string,     author: string,     upvotes: {         type: number,         default: 0     },     post: {         type: mongoose.schema.types.objectid,         ref: 'post'     } });  mongoose.model('comment', commentschema);

post posts that's working

router.post('/posts', function(req, res, next) {     var post = new post(req.body);     post.save(function(err, post) {         if (err) {             return next(err);         }         res.json(post);     }); });

post comments that's not working

router.post('/posts/:post/comments', function(req, res, next) {     var comment = new comment(req.body);     comment.post = req.post;      comment.save = function(err, comment) {         if (err) {             return next(err);         }         req.post.comments.push(comment);         req.post.save(function(err, post) {             if (err) {                 return next(err);             }              res.json(comment);         });     }; });

and i'm using following curl post creation (this 1 working)

curl --data 'title=test12&link=http://test12.com&comments=bla' http://localhost:3000/posts

and 1 comments that's not working

curl --data 'something'  http://localhost:3000/posts/58302f9662aa080ec9d75068/comments

the response call server is:

post /posts/58302f9662aa080ec9d75068/comments - - ms - -

please resolve issue.

there few issues:

comment.post = req.post

i think mean req.params.post here (refering :post placeholder in url pattern), not req.post.

comment.save = function(err, comment) { ... }

you want call comment.save, not assign new function it:

comment.save(function(err, comment) { ... })
