I don't understand why request to create an object is no longer valid. I create models with mysql and sequelize.
I fill in the user's token for each request, to connect, retrieve his profile, retrieve all the articles from the database and it works, but now I can't create any more articles.
I did console.log(req.body)of my function but I have this : {}. My function gives me a 400 error from my first condition.When I send my request, on VSC I have " code: 'ERR_HTTP_HEADERS_SENT'".
I checked the number of characters that should match the sequelize patterns, it's good. I filled in the 3 fields on postman, title, description and userId.
//*******Creating an article*******//
exports.createArticle = (req, res, next) => {
//Nous allons renvoyer 2 paramêtre //
const title = req.body.title;
const description = req.body.description;
console.log(req.body);
// Fields must not be empty before sending //
if (title == null || description == null) {
res.status(400).json({ message: "content can not empty" });
}
console.log(req.body);
//***Build the request body****/
const article = Article.build({
title: req.body.title,
description: req.body.description,
userId: req.userId,
});
console.log(article);
//***Save new article***//
article
.save()
.then(() => res.status(201).json({ article }))
.catch((error) => res.status(400).json({ error }));
};As even after returning { message: "content can not empty" }, your code is continuing execution and sends another response, if you didn't provide title or description.
Please modify your code as per below code
exports.createArticle = (req, res, next) => {
//Nous allons renvoyer 2 paramêtre //
const title = req.body.title;
const description = req.body.description;
console.log(req.body);
// Fields must not be empty before sending //
if (title == null || description == null) {
res.status(400).json({ message: "content can not empty" });
return;
}
console.log(req.body);
//***Build the request body****/
const article = Article.build({
title: req.body.title,
description: req.body.description,
userId: req.userId,
});
console.log(article);
//***Save new article***//
article
.save()
.then(() => res.status(201).json({ article }))
.catch((error) => res.status(400).json({ error }));
};
