从客户端到服务器（流星）调用方法

Question

Client Side

Users = new Mongo.Collection("user-info");
if (Meteor.isClient) {
    var myApp = angular.module('calorie-counter', ['angular-meteor']);
    myApp.controller('formCtrl', ['$scope', function ($scope) {

        $scope.user = {
            item1: 0,
            item2: 0
        };

        $scope.submit = function () {
            Meteor.call("submit" ($scope.user));
        }
    }]);
}

Server side:

if (Meteor.isServer) {
    Meteor.methods({
        submit: function (user) {
            Users.insert(user);
        }
    });
}

What I'm attempting to do is when the user clicks on the submit button on the client side, I want it to call a server side method where the information that the User entered will be saved into the collection. I'm passing in the $scope.user as a parameter (not too sure if I'm calling the method correctly) but the error I keep receiving is "submit is not a function". Initially, I was just inserting the $scope.user directly from that function, but I thought that type of an operation might be more suitable for the server side? (I'm not too sure if I'm thinking of this right or just overthinking)

Answer 1

You need to use , after method name to pass parameters

Meteor.call("submit", $scope.user);
//           ^^^^^^^  ^^^^^^^^^^^
//           Method   Parameter

Documentation

Example

For multiple parameters, use comma-separator between parameters

// sync call
var result = Meteor.call('foo', 1, 2);

Also, all the database operations should be done on Server side for security. Otherwise end users( hackers ) can gain the access to database and can attack on your DB.

Make sure you move all the database handling code on server and remove the package named insecure . This is the package that allow you to access DB from client-side.

Answer 2

This isn't a valid syntax:

Meteor.call("submit"($scope.user));

You need to pass it as a parameter. Please change it to:

Meteor.call("submit", $scope.user);
