Mongoose 创建操作在删除操作后无法立即运行

Question

I am trying to repopulate my collection on an API call using the data I receive. I basically want to wipe of the entire collection(s) and repopulate them with the new data I have received in my API call.

The creation operations work fine if I don't run the delete operations. However if I try running the delete operations first, no new documents are created.

Here is a stripped down version of my controller function:

let { data } = req.body
try {
    let result = await Record.deleteMany({});
} catch (err) {
    res.status(400).json('Unable to clean database');
}
for (let i in data) {
    await Record.create(data[i]);
}
return res.status(200).json('Successfully Processed CSV')

How do I go about resolving this? Basically all I want is to delete all documents within the collection and add the new documents immediately after.

use for of if data is an array of objects you can do like this:

let { data } = req.body
for (let newRecord of data) {
    await Record.create(newRecord );
}
