更改 Mongoose 模式类型不起作用

Question

I have a mongoose schema with a property which was a string array.

docs: [String]

I changed the type to an object array as follows

docs: [{ url: String, type: String }]

But when I create a new item, the docs field is still validated with the type string and the following error is thrown.

I even tried dropping the collection and it still not works.

Answer 1

The brackets should be around the type, and not the entire object. As documented here , instead of your Schema being:

docs: [{ url: String, type: String }]

It should be

docs: { url: String, type: [String] }
