在模型内创建子文档并将其添加到数组中

Question

我正在接受identityResponse的响应，该响应为我提供了一个“帐户”数组，然后我需要运行一个for循环来创建每个帐户。对于每个帐户，我还需要将User文档作为子文档数组放入。我似乎不知道该怎么做。我已经有了它来创建帐户，但是它不会推送到用户模型中。

我已经尝试过findOneAndUpdate，让newAccount = new PlaidUserAccounts，尝试过一个发送结果的承诺，然后将其推送到User.plaidAccounts中。

也许我可以直接在User Profile中创建它，同时在PlaidUserAccounts中创建它？还是仅在用户内部创建它？

app.get('/updateUser', function (request, response, next) {

  client.getIdentity(ACCESS_TOKEN, function (error, identityResponse) {
    if (error != null) {
      prettyPrintResponse(error);
      return response.json({
        error: error,
      });
    }

    // CREATE ACCOUNTS

    for (let i = 0; i < identityResponse.accounts.length; i++) {
      db.PlaidUserAccounts.create({
        userID: response._id,
        accessToken: ACCESS_TOKEN,
        account_id: identityResponse.accounts[i].account_id,
        accountName: identityResponse.accounts[i].name,
        official_name: identityResponse.accounts[i].official_name,
        availableBalance: identityResponse.accounts[i].balances.available,
        mask: identityResponse.accounts[i].mask,
        type: identityResponse.accounts[i].type,
        subtype: identityResponse.accounts[i].subtype,
      });
    }
// Push into User Profile
  })
}


let userSchema = new Schema({
