javascript - Make a meteor publication reactive to time -

-

i'm having little trouble figuring out how make subscription reactive publication query.

my publication follows:

meteor.publish('alldata', function(){     return data.find({ttl: {$gt: new date()}}) })

as can see, documents contain ttl field. long time live still greater current time, can sent client, if not, shouldn't.

the subscription:

this.autorun(() => {     this.subscribe('alldata') })

on initial load, data fine, whenever ttl expires, document remains on client unless reload page. there anyway handle reactively, making expired documents disappear client?

a combination of reactivevar , autorun did trick me. it's possible overkill, works.

let cutofftimestamp = new reactivevar();  meteor.setinterval(function() {     cutofftimestamp.set(date.now() - 1); }, 60000);  meteor.publish("mypub", function() {     this.autorun(function() {         return mycollection.find({ timestamp: { $gte: cutofftimestamp.get(); } });     }); });

this error has shown on many times, seems. prominent answer issue seems restkit 0.20 — coredata: error: failed call designated initializer on nsmanagedobject class however, solution posted doesn't work me. let's start beginning: i want upload file server. want parse response make sure uploaded. if not, try again later. model has boolean variable called nsnumber *senttoserver purpose (in coredata, bool saved nsnumber ) . because don't know whether sending going successful, save entity coredata model first before sending via restkit. when post request successful, server returns json string this: {"id":14,"created":true} notice that, of course, id not set on coredata model yet, both id , created new informations model. here's model: @interface recording : nsmanagedobject @property (nonatomic, retain) nsstring * audiofilepath; @property (nonatomic, retain) nsdate * createdat; @property (nonatomic, retain) nsstring * deviceid; @
