meteor

问题 So basically, the client calls the server using a Meteor.call . The server method then does some validations and calls a web service using a meteor package. If validation fails and a meteor error is thrown, it reaches the server. If the package response has an error, it only logs on the server. I need the error to reach the client. Here's how the code looks like. Client Meteor.call('callService', (err, result) => { if(err) { console.log(err.reason); } }); Server Meteor.methods({ 'callService'

问题 So I have a poll template that can have as many questions as the user wants. How do I insert all the questions into an element of a collection? Since I only had three before, I inserted them manually like this: var newPoll = { question: event.target.question.value, choices: [ { text: event.target.choice1.value, votes: 0 }, { text: event.target.choice2.value, votes: 0 }, { text: event.target.choice3.value, votes: 0 } ], usersWhoVoted: [], poll_is_open: true, time_poll_closed: null, }; If I can

问题 I've installed webshot package and meteor webshot smart package from: https://github.com/TimHeckel/meteor-webshot In the directory pacages/webshot/lib/webshot.js there is definition of WEBSHOT object. In the default meteor application I want to use this object to get the snapshot as show in the second step from the link above: Template.hello.events({ 'click input' : function () { var _image = "myscreenshot.png"; var _res = WEBSHOT.snap("http://google.com", "public/exports~/" + _image, {

问题 I am using Meteor iron:router. I have a template called by the name 'multi'. So whenever I have paths like '/multi' or '/multi/BSC123' , I want 'multi' to be rendered. So far I have used an array approach like this Router.route('multi',{ path:['/multi','/multi/:_id'] }); This works fine. But when I use this approach, my left nav bar which has a href link to 'multi' template is not shown. So apart from the above approach, can anyone suggest me other solution where I can have two paths and same

问题 I'm relatively new to Meteor (especially Iron Router), and have been stuck on the following issue... I have a route which displays details about a single post: this.route('singlePost',{ path:'/posts/:_id', data:function(){ return Posts.findOne(this.params._id); } }); This works fine, but I'd like to be able to show the post owner's username in the URL, rather than the static "/posts/" path, ex: this.route('singlePost',{ path:'/:username/:_id', data:function(){ return Posts.findOne(this.params

问题 I have included the UserAccounts (Semantic UI) package with the meteor app. On inserting the routes and the {{> atForm}}, this is how my front page looks.

Formatting is still the one in the picture. Can someone please help or provide advice? Let me know which codes you need to review, I'll post them on

问题 I'll preface this by saying I have very little coding knowledge other than a few mongo tutorials so this may be a very simple answer, I'm trying to extract the data from my meteor project into a text file that can be edited. Previously I've just had meteor (and Node.js) installed but I've installed MongoDB because without it my cmd window would tell me "'mongodump' is not recognized as an internal or external command, operable program or batch file" I then followed the instructions here and

问题 I'm still struggling to get a calendar to re-render when data changes using meteor blaze. I have put in place an observerChanges function that is firing happily when added, removed or changed are triggered, but I have NO idea how to actually make the calendar update its state. The handler code is Meteor.subscribe("reqEvents"); allReqsCursor = Requests.find(); var handle = allReqsCursor.observeChanges({ added: function (id, user) { console.log("Request added"); }, removed: function () {
