问题 Campaign data is storing except user reference in MongoDB campaign collection. How do I render only campaigns that were created by the user but not all campaigns by every user? I need this after the user logged in to website. Campaign schema var mongoose = require('mongoose'); var Schema = mongoose.Schema; var campaignSchema = new Schema({ Title: {type: String}, Description: { type: String }, Rules: {} , Banner: { type: String }, user: { type: mongoose.Schema.Types.ObjectId, ref: 'User' } });

问题 I and the team got a task to implement multiple themes for our project (keeping in mind that we have a single-theme project right now). By theme I don't mean just CSS , I mean different markup files, certain features for certain things, etc. (If you don't like the word 'theme' in this context don't use it, I hope you get the idea: some things need to be reused across the codebase, some things need to be specific to a theme ). Overall, we have no problem of structuring it in a maintainable way

问题 I've got a simple blog app on Express and MongoDB, using EJS to render my data. The problem I have is I want this to be styled like a paragraph: <div class="show-post__content"> <%= post.body %> </div> The content of the post.body is: '<p>Hello there, this is a new post.</p>' but it's rendering like this: If the picture doesn't work, it's showing up with the brackets visible, rather than looking like an actual html p tag if that makes any sense...

问题 I'm making a browser game that utilizes voice communication, to record audio in the browser I'm using wami-recorder which uses flash to send a POST request to the server with the recorded audio, only it doesn't seem to give me any control over the request. My game server, which is written in node.js/express, needs to be able to identify the client from the audio it's received, as well as pair it with the correct web socket from socket.io I've considered using the ip address, however it wouldn

问题 I need the help/support/guidance regarding the Socket.io On My server page i.e app.js, I initialized the Socket and it works fine. Now I want to call the emit function to some other page. But I did not get the event from another page because the event generated under connection. I will share the pseudo code by which you can get some idea about app.js page const io = require('socket.io'); const server = io.listen(3003); const triggerEvent = (socket) => { return socket.emit('event-trigger',

问题 I am looking for a way to query a database with Mongoose based on an array of document IDs and return the results in the order in which they were presented to Mongoose within that array. For example if I provided Mongoose with this array ["112", "111", "113"] and assuming that all the documents with these IDs exist the result will be an array of documents ordered accordingly as: [{//112},{//111},{//113}] Just to be crystal clear, I don't need to sort the array by any specific document field -
