问题 I have a fairly typical need, to ensure an insert / update has finished before I run a find. The code goes something like this: //Update my collections Messages.insert({author:_id,text:text}); Authors.update({_id:_id},{$inc:{messages:1}}); //Wait until the update / insert has finished //Perform some actions on the collections just updated var author = Authors.findOne({task:taskId},{sort:{'messages':1}}); //Do some more complex stuff... While in most cases this would be fine as asynchronous

问题 This is suppose to look at the users category selection and then update the subcategory. The solution was recommended by someone else but I can't seem to get it to work.

I have an object that I want to update using Auto-Form and Collections2 with meteor. //Schema Records = new Mongo.Collection('records'); var Schemas = {}; Schemas.Record = new SimpleSchema({ title: { type: String, label: "Title", max: 200 }, caption: { type: String, label: "Caption", max: 200 }, text: { type: String, label: "Detailed text", optional: true, max: 1000 }, loc: { type: Object, optional: true, blackbox: true },

问题 In my meteor web app I am trying to change the background of a certain element conditionally with this code: .popular-games{ background-image: url({{background}}); } {{background}} being the path it should follow to find the image. This will not work though because the url path needs quotes, and when I put in quotes in negates {{background}}. I've tried putting the quotes into the source where {{background}} is coming from with this code: background: "\"images/gameArt/fallout4.jpg\"" trying

问题 I have removed autopublish from my Meteor app. Now I'm publishing my collections manually. I have some related collections. I want to increase performance as much as possible. If I'm, for instance, looking at a post and want to see all the comments related to this post, I have to query the database with both post: Posts.findOne(postId) AND comments: Comments.find({postId: postId}) . I am querying the two collections in the data field with iron-router so they are present in my template but I'm

问题 I'm trying to implement the "reset password" functionality in my Meteor app. I have a very simple implementation of it based on this tutorial: Julien's tutorial on gentlenode There are several examples floating around that use this same basic approach. I did mine almost exactly like Julien's but I used only one template; I use an {{#if}} in my template that displays the 'reset password' form, if my session variable sResetPassword is not falsey.
