node.js - Cannot process POST request in Sails.js correctly -


i'm trying add comments functionality sails.js blog application. however, don't seem write controller action correctly.

when submit comment form, page starts reload, not finish reloading.

here's controller code:

const gravatar = require('gravatar');  module.exports = {      blog: (req, res) => {         post.find({}).exec((err, posts) => {             if (err) {                 res.send(500, { error: 'database error' });             }              res.view('all-posts', { posts });         });      },      singlepost: (req, res) => {         post.findonebyslug(req.params.slug).exec((err, post) => {             if (err) {                 res.send(500, { error: 'database error' });             }              res.view('single-post', {                 post,                 gravatar: gravatar.url             });         });     },  addcomment: (req, res) => {     const {         name, comment, email,         url, slug,     } = req.allparams();      post.findonebyslug(slug).exec((err, post) => {         if (err) {             return res.send(500, { error: 'database error' });              comment.create({                 body: comment, name, email, website: url             }).exec((error, comment) => {                 if (error) {                     return res.send(500, { error: 'database error' });                 }                 console.log(comment);                 post.comments.addcomment({slug, comment});                 post.save();                  res.redirect(`/${slug}`);             });         }     });      return false; },  };

and here's routes.js file:

module.exports.routes = {   'get /blog': 'blogcontroller.blog',    'get /:slug': 'blogcontroller.singlepost',    'post /:slug/new-comment': 'blogcontroller.addcomment' };

and model post.js

module.exports = {    identity: 'post',    attributes: {      title: {       type: 'string',       required: true,       unique: true     },      body: {       type: 'string'     },      categories: {       type: 'string',       required: true     },      imageurl: {       type: 'string'     },      comments: {       collection: 'comment',       via: 'post'     },      slug: {       type: 'slug',       from: 'title',       blacklist: ['search', 'blog', 'contacts']     }   },    addcomment: (options, cb) => {     post.findonebyslug(options.slug).exec((err, post) => {       if (err) return cb(err);       if (!post) return cb(new error('post not found.'));        post.comments.add(options.comment);       post.save(cb);     })   },    connection: 'mongodb' };

so, when submit comment form on /:slug page, nothing happens accept page tries reload. , in database nothing gets saved well.

the form parameters sent form, on client side should fine.

how how approach post request correctly?

you need add return statement before each res.send(500, ...); call, because currently, in case of error, code tries send response twice, , client doesn't response actual error:

if (err) {   return res.send(500, { error: 'database error' }); } ... rest code

i suspect, reason why nothing saved in db invalid parameters in request body.
