javascript - Parse query AND operator on the server -

i'm using parse send push notifications , need send users subscribed 2 channels: 1 main channel , @ least 1 of list of secondary channels. tried use 1 query suggested in parse forum didn't work :(

//query main channel var query1 = new parse.query(parse.installation); query1.equalto('channels', main); //query secondary channels var query2 = new parse.query(parse.installation); query2.containedin('channels', secondarylist); //desired result parsequery mainquery = parsequery.and(query1, query2); parse.push.send({                where: mainquery,               data: {                 alert: req.body.message,                 uri: req.body.url              }             }, {               success: function() {                 console.log("push successful");               },               error: function(error) {                 console.error(error);               }             }); 

no such thing query.and(). conjunction qualifying single query:

var justonequery = new parse.query(parse.installation); justonequery.equalto('channels', main); justonequery.containedin('channels', secondarylist); parse.push.send({            where: justonequery,           // ... 

since both tests contents of channels column, presumably array, single query can qualified single condition:

var main = "foo"; var secondarylist = ["bar", "baz"]; var singlelist = secondarylist.concat(main);  // 1 constraint same other 2 justonequery.containedin('channels', singlelist);  // or same thing 3 equalto justonequery.equalto('channels', "foo"); justonequery.equalto('channels', "bar"); justonequery.equalto('channels', "baz"); 

i suggest query working above, few hard-coded variables know in data. once know query works, can concentrate on making sure call function properly.
