I have looked everywhere, and I have not found an easy to understand method of updating a sequelize array, like this with a normal string:
db.User.update({name:req.body.name},{where : {username:req.body.username}}).then(function(user) {
res.json(user);
})
Sequelize doesn't support bulk updates using an array, see https://github.com/sequelize/sequelize/issues/4501
You have to implement a custom function. Here is a basic example to give you an idea :
var promises = [];
userArray.forEach(function(user){
promises.push(db.User.update({name:user.name},{where : {username:user.username}});
});
Promise.all(promises).then(function(){
// success
}, function(err){
// error
});
Which I myself resolved as follows:
case 1: If you want to update multiple lines at the same value with different conditions
db.User.update({ name: 'name request' }, {
where: {
$or: [{ name: 'test 1', password: 'sasaccsa' }, {
name: "test 2"
}]
}
}).then(function(user) {
//query generate
// UPDATE `User` SET `name`='name request' WHERE ((`name` = 'test 1' AND `password` = 'sasaccsa') OR `name` = 'test 2')
res.json(user);
});
case 2: if you want to update multiple lines with different values for different types of reviews:
var arrayUpdate = [{
name: 'test 1',
id: 1
}, {
name: 'test 2',
id: 2
}, {
name: 'test 3',
id: 3
}];
sequelize.Promise.each(arrayUpdate, function(val, index) {
return db.User.update({
name: val.name
},{
where:{
id: val.id
}
}).then(function(user) {
}, function(err){
});
})
.then(function(updateAll){
//done update all
res.json(updateAll);
}, function(err){
});
