how to get array of sequelize and mysql objects? - mysql

Question

hello I have a nodejs project, I am using sequelize and mysql2 to access the database, in one of its routes I show an ejs view and I want to send a variable to it so that different products/cards are dynamically loaded from a form.
now when I use the findAll() method to call the different mysql records I try to bring an array of objects but it returns the loose objects so in the ejs view I cannot iterate with a foreach() for example
I execute this from a home route
i try this
products_dataBase.findAll()
.then(products => {
products.forEach(element => {
let result = []
result.push( element.dataValues)
res.render('home.ejs', { result });
console.log(result)
});
})
.catch(err => {
console.log(err)
})

res.render must be executed only once per request, but you invoke it repeatedly, in a forEach loop. Try this:
products_dataBase.findAll()
.then(products => {
let result = [];
products.forEach(element => {
result.push(element.dataValues);
});
res.render('home.ejs', { result });
console.log(result);
})
.catch(err => {
console.log(err);
});
