如何删除 mongoose 中的Many

Question

I have a database like this:

User {
 id: 12323,
 name: asdasd,
 products: [{ id: 1, name: asdasdl }, {id: 2, name: bfcvc}]
}

With deleteMany , I want to remove all that have products name 'asdasdl' .

How can I do this?

I have this code but it doesn't work:

await User.deleteMany({'name': { '$in': User.products }}, {});

Thank you!

Answer 1

You can use the $eq operator like this

await User.deleteMany({ 'products.name': { $e: 'asdasdl' }});

Answer 2

By changing the query parameter, you can get all documents with a products.name == 'asdasdl' and then delete them:

await User.deleteMany({ 'products' : { 'name': 'asdasdl' }}); 

See deleteMany docs here and Mongo queries on arrays here

Answer 3

Thank you for your answer.

In fact I don't want to delete the Users, I want to delete the products. So if the name is 'asdasdl', delete that product.

Thank you!
