如何使用 mongoose 将来自 model.findOne() 的查询保存在变量上

Question

I am trying to save the results from model.findOne() on a variable for using the results on another function. But what I get on the variable is only a pending promise:

let key = Product.findOne({ name: 'keyboard' }).then(data => { return data });
console.log(key);

and what I see on mongo shell:

Promise { <pending> }

Answer 1

key is not the result of findOne(), it is a promise. The promise has not resolved.

To make your example work, change the code:

let key = await Product.findOne({ name: 'keyboard' }).exec();
