javascript - How can I send a Parse Push notification only to installations that are subscribed to two channels, not either/or? -


i know according documentation, if wanted send push notification installations in "giants" , "mets" channels, so:

parse.push.send({   channels: [ "giants", "mets" ],   data: {     alert: "the giants won against mets 2-3."   } }, {   success: function() {     // push successful   },   error: function(error) {     // handle error   } });

what want however, send push notification installations in both channels, not 1 of them only.

so going off example above, rather sending installation in "giants" or "mets" channels, send installations in both @ same time, not ones have "giants" or "mets". there way this?

the alternative sending channels based push, push-to-query. construct parse.query matching installations want, , send way.

because of this, can use 'containsall' constraint on channel key. give shot.

var query = new parse.query(parse.installation); query.containsall("channels", ["giants", "mets"]);  parse.push.send({   where: query,   data: {     alert: "the mets won!"   } }).then(function() {   // success }, function(error) {   // error });
