Node mysql cannot get a response on a query - mysql

Question

I have a trouble when i pass a function inside my query. When i run my code without the function just work without any problem. With it on postman is stuck on "Sending request"
Example:
save() {
return db.query(
{
sql: "INSERT INTO contenido (titulo, extencion_archivo, fecha_publicacion) VALUES (?, ?, ?)",
values: [this.titulo, this.extension, this.fecha]
}, function(err, res, fields) {
//More code
}
);
}
Following code work without any problem:
save() {
return db.query(
{
sql: "INSERT INTO contenido (titulo, extencion_archivo, fecha_publicacion) VALUES (?, ?, ?)",
values: [this.titulo, this.extension, this.fecha]
}
);
}
How i call save method:
exports.addVideo = (req, res, next) => {
const titulo = req.body.titulo;
const extension = req.file.mimetype.split("/")[1];
const fecha = new Date();
const videoUrl = req.file.filename;
const video = new Videos(null, titulo, extension, fecha, videoUrl);
video.save().then(() => {
res.json('sending')
})
};

You are using .then on function save() which is not promise returning function. I think that may be the reason for you not getting any response for your postman request.
Try running this code :
function save() {
return new Promise((resolve, reject) => {
db.query(
{
sql: "INSERT INTO contenido (titulo, extencion_archivo, fecha_publicacion) VALUES (?, ?, ?)",
values: [this.titulo, this.extension, this.fecha]
}, function (err, res, fields) {
if (err) {
console.log("Error Occurred :", err);
reject();
}
console.log("Successfully Sent :", res);
resolve();
}
);
})
}
and
exports.addVideo = (req, res, next) => {
const titulo = req.body.titulo;
const extension = req.file.mimetype.split("/")[1];
const fecha = new Date();
const videoUrl = req.file.filename;
const video = new Videos(null, titulo, extension, fecha, videoUrl);
video.save().then(() => {
res.json('sending')
}).catch(() =>{
res.json('Error Occurred')
})
};
Please try this if it works well and good else let me know I will try to help you around this.
