mongoose

问题 I have a fully functioning CRUD app that I'm building some additional functionality for. The new functionality allows users to make changes to a list of vendors. They can add new vendors, update them and delete them. The add and delete seem to be working just fine, but updating doesn't seem to be working even though it follows a similar method I use in the existing CRUD functionality elsewhere in the app. Here's my code: // async function from AXIOS request const { original, updatedVendor } =

问题 I am currently converting my API from JS to TS. However, I'm having some difficulties with mongoose & typescript. Specifically, this is not available inside my instance methods.

问题 The first problem I am having is that whenever I try to delete the Comment, I also try to find the index of that specific comment inside post.comments as well as inside user.comments , it consistently returns -1, the reason why I am trying to find it, is so that I can splice it from the comments array that user and post do have. The second problem I am having is that whenever I create a comment, I try to store it in the comments array that user and post have, but it stores it only as a string
