Estoy tratando de actualizar un modelo de secuela (llamado conversación) cada vez que inserto un valor en su asociación (llamado mensaje). El modelo de conversación no se actualiza automáticamente y no he encontrado ninguna información útil en los documentos.

 const router = require("express").Router(); const { Conversation, Message } = require("../../db/models"); const onlineUsers = require("../../onlineUsers"); // expects {recipientId, text, conversationId } in body (conversationId will be null if no conversation exists yet) router.post("/", async (req, res, next) => { try { if (!req.user) { return res.sendStatus(401); } const senderId = req.user.id; const { recipientId, text, conversationId, sender } = req.body; // if we already know conversation id, we can save time and just add it to message and return if (conversationId) { const message = await Message.create({ senderId, text, conversationId }); Conversation.update({ }) return res.json({ message, sender }); } // if we don't have conversation id, find a conversation to make sure it doesn't already exist let conversation = await Conversation.findConversation( senderId, recipientId ); if (!conversation) { // create conversation conversation = await Conversation.create({ user1Id: senderId, user2Id: recipientId, }); if (onlineUsers.includes(sender.id)) { sender.online = true; } } const message = await Message.create({ senderId, text, conversationId: conversation.id, }); res.json({ message, sender }); } catch (error) { next(error); } }); module.exports = router;
