In console(Status button) is possible to see:
collection.remove is deprecated. Use deleteOne, deleteMany, or bulkWrite instead.
Instead Person.remove
should be Person.deleteMany
In case of error is at the end condition - ternary operator or if statement
whole solution:
var removeManyPeople = function(done) {
var nameToRemove = "Mary";
Person.deleteMany({name: nameToRemove}, (err, data)=> {
err ? done(err) : done(null,data)
}
)};
Having the same problem here. Tried many different ways without any success.
Here is my code
var removeManyPeople = function(done) {
var nameToRemove = "Mary";
Person.deleteMany({name: nameToRemove}, function(err, data) {
if (err) {
done(err);
} else {
done(null, data);
}
});
};
Any hints or suggestions would highly be appreciated.
I have solved the problem by using new database from mlab. Somehow, the old database that I was using was not working properly.
I forgot what I did but there are definitely answers in the documentation and stack-overflow. There are different options just try them and you will find one that works.
Thanks so much. I was stuck on this for a long time. I couldn’t figure out what I was doing wrong. Finally I took your suggestion and decided to use a new database and it worked.
In my original schema I used unique for name. Once I eliminated that, I thought it would work, but it didn’t. I’m still not sure if that affected it.
Thanks again.
Yes, I also think so.
I also think if you have repetition of/more done(null, data); on the same page. It makes it fail. I got the same issue but I removed one and it passed no need for a new database.
`var removeManyPeople = function(done) {
var nameToRemove = “Mary”;
Person.deleteMany(
{name: nameToRemove},
(err, data) => {
if (err) {
done(err);
}
done(null, data);
}
)
//done(null/, data/);
};`
Thanks so much. That worked!
If you’ve defined the schema where the ‘name’ field is set with ‘unique’ index. At solution validation, you’d get this error:
Error: E11000 duplicate key error collection: test.people index: name_1 dup key: { name: “Mary” }
The reason is fCC stubs a couple records (documents) with the same ‘name’ value (Mary).
e.g [ { name: ‘Mary’, age: 16, favoriteFoods: [ ‘lollipop’ ] },
{ name: ‘Mary’, age: 21, favoriteFoods: [ ‘steak’ ] } ]
Fix to pass validation:
Note:
Model.remove() or Model.deleteMany() should both work
Thanks a ton!!!
try using this it worked on one try
var removeManyPeople = function(done) {
var nameToRemove = “Mary”;
Person.remove({name:nameToRemove},(err,data)=>{
if(err)
return console.log(err);
done(null,data);
});
};
