流星方法未在服务器上运行

Question

I have the following code,

Meteor.methods({
  markPaid: function(expense) {
    check(this.userId, String);
    check(expense.id, String);

    Expenses.update({'_id': expense.id}, {$set: {paid: true}}, function(error) {
      return error;
    });
  }
});

called by

Meteor.call('markPaid', expense, function(error, result) {
  //handle error if any.
});

When I call this from my client the code executes client side, as is expected with meteor's so-called optimistic UI, but the method does not run server side. My actual database never updates.

Thank you!

Answer 1

according the Meteor docs on Meteor.call (cf https://docs.meteor.com/api/methods.html#Meteor-call )

Meteor.call(name, [arg1, arg2...], [asyncCallback])

ARGUMENTS

arg1, arg2... EJSON-able Object Optional method arguments

the arguments must be JSON. a moment object is not JSON. that's why passing an id, as you did, works, but your full JS object does not.

Answer 2

Is the method being called inside observechanges? I had a similar issue:

let a = MyCollection.find({something:'something'}); 
a.observeChanges ({
    changed( id, fields) {
        console.log('Im here');
        Meteor.call ('awesomeMethod', 
            'param',
             (error, ans) => {
                 handel error; return; }                                    
                 console.log(ans);
             }
         );                
    }
});

And the same things were happening; only the simulation was running, but calling the method from the console worked well, so I decided to change the Meteor call to another place.
